Ligno-VersaTec, a Multi-Function Meter: Pin - Pinless - RH
PIN
SCAN
RH
The Ligno-VersaTec comes with 250 built-in corrections for measuring different wood
species, bamboo, panel products, sheetrock, wall boards and reference scales (page 6) for
measuring concrete and other building materials.
The Ligno-VersaTec with RH BluePeg probe and adapter RH can measure relative hu-
midity, temperature, dew point and GPP. Accessories are available for in-situ RH mois-
ture testing of concrete slabs and wall cavities.
1. Use as Pinless Meter: You can use the Ligno-VersaTec
meter by itself as a dual-depth pinless meter with select-
able measuring depth 3/4” and 1/4”. The pinless mode of
the Ligno-VersaTec has the same features as the
Ligno-Scanner SDM.
2. Use as Thermo-Hygrometer: Add fast-responding,
precision RH BluePeg probe. The connection between
meter and probe can be made by the adapter RH or an ex-
tension cable. Ligno-VersaTec indicates ambient relative
humidity and temperature, GPP and dew point.
3. Use for in-situ RH Testing in Concrete: Add RH
cable, sleeves and the removable RH probes for in-situ RH
testing. The Lignomat system complies to ASTM F2170.
Pin or pinless mode can be used to take qualitative mois-
ture measurements in concrete. ASTM F2659. Page 19.
4. Use as Pin Meter:
- Add slide hammer electrode E12. Teflon-coated pins allow
measuring up to 2” deep. Differences between surface and
core moisture can be detected with the electrode E12.
- Add inspector electrode E14V. The E14V is a tool used in
construction and restoration to track moisture problems.
Easily measures in corners, behind moldings, under base
boards and other hard-to-reach places. The handle can be
elongated by a broom stick to reach high up or down low.
Add EL pins 7” long.
E14V with EG pins 3/4” is also used to measure hard ma-
terials (bamboo). Page 9.
- Add specialty electrode E16 to measure concrete and oth-
er hard building materials. Page 4.
The pin mode of the Ligno-VersaTec has the same features
as the Lignometer K.

Check and Change Settings for Pin / Pinless Mode
Before using the Ligno-VersaTec, the active settings in the meter need to be checked and if nec-
essary changed to fit the material to be measured. When the Ligno-VersaTec is turned on, the
previously chosen settings are active.
To recall active settings, press the SET/HOLD key repeatedly.
To change settings use up or down keys.
1st Measuring mode: Pin or scan (pinless).
2nd Settings for wood and non-wood materials:
# 0-250. Corrections for different wood
species and non-wood materials are needed
in pin and scan mode. Check table below and
pocket-guide for available settings for pin and/or pinless mode.
3rd Setting for wood temperature: Wood temperature corrections
are only needed in pin mode. It is difficult to determine the
temperature of the wood at the depth of the pins. Page 7(2).
4th Setting for measuring depth: 1/4” and 3/4”. Measuring depth is
only used in pinless mode. Page 12.
The settings for the most common wood species, bamboo products and different building ma-
terials are listed on the laminated pocket guide included with the meter. For unlisted species or
new products call customer service at 800-227-2105. If no setting is available, Lignomat offers
testing to determine the correct setting.
See table below: Not all settings #0 - 250 are available for pin and pinless mode.
If the wood or material setting is not available in pin and pinless mode, the meter will automat-
ically select the available mode. If the number is not defined at all, the mode indicated at the left
side of the display toggles between PIN and SCAN.
Example: Setting #30 is only available in SCAN mode. When the meter is in PIN mode and the
setting #30 is selected, the meter automatically switches to SCAN mode.

Pin Technology
The Ligno-VersaTec functions as a resistance-type moisture meter in pin mode. The conductiv-
ity between the pins is measured and the moisture content is calculated according to the active
settings for wood species and wood temperature. The meter indicates the highest moisture value
within the small measuring area between the tips of the teflonized pins.
The Ligno-VersaTec pin measurements have to be corrected for:
(1) Wood species and other materials being measured.
(2) Wood temperature.
- Settings for measuring depth do not affect pin measurements.
(1) The settings for the most common wood species, bamboo products and different building
materials are listed in the laminated pocket guide included with the meter. For unlisted species or
new products call customer service at 800-227-2105. If no setting is available, Lignomat offers
testing to determine the correct setting.
Moisture measurements of individual wood species, 5-99.9% 111-230
Bamboo in pin mode within wood settings, 5-99.9% 170-180
Reference scale for laminates and composites made of wood, 0-99.9 0
Sheetrock (light-weight) and gypsum, 0.1-22% 15 (109)
Wallboards: interior, exterior, water resistant, light-weight 107-109
Reference scale for concrete and other similar materials, 0-99 25 (105)
Reference scale for bldg materials other than concrete or sheetrock, 0-99 10 (110)
Wood groups used in older Lignomat pin meters, 5-99.9% 1-4, 101-104
(2) The meter needs to be set for the correct wood temperature. Different ambient airtempera-
tures do not affect the readings. However, measuring hot or cold lumber will affect the readings.
The Ligno-VersaTec has corrections for different wood temperatures built-in. Once you set the
meter for the wood temperature and for the wood species, the corrected moisture value is dis-
played. Temperature adjustments are not necessary if the meter is set for a wood temperature of
70°F and the lumber is within 55-85°F.
It is difficult to actually measure the wood temperature at the depth, where the tips of the elec-
trode pins are measuring. If the wood has been acclimated to the ambient (air) temperature,
choose the ambient temperature. If the wood is not acclimated, choose the average temperature
over the last few hours.

Measurements
After settings have been checked and changed, press the READ key to obtain
readings. The active settings appear briefly.
If no electrode is connected or if the electrode is not inserted into any material,
the lowest possible reading for the active material and temperature settings
appears. Example: PIN/Min is 5% for setting 147 for 70°F.
If an electrode is connected and inserted into material, the moisture value and
the active settings for material and wood temperature are displayed.
Example: Wood species 147, wood temperature 85°F, measured value 6.9%.

While taking measurements:
- If the material is too dry to be measured, the meter will show the lowest possible value
indicated by PIN/Min on the left side of the display.
- If the material is too wet to be measured, the highest possible value is indicated by PIN/Max on
the left side of the display.
Obtain stable Readings at low Moisture Contents
- Minimize electro-magnetic interference: If you measure close to computers, electrical wires or
power tools in use, readings could become erratic. To avoid the interference, take measurements
in a different location.
- Reduce static electricity: In dry climates and at low moisture contents static electricity may cause
erratic readings. The wood, the meter and the person holding the meter should not move while
taking measurements. Best results are achieved, when the meter is placed on the board to be
measured.
Measuring Wood
Select the correct setting for wood species and wood
temperature. Page 7.
Range for Wood: 5-99%. Measurements above fiber
saturation point (25-30%) are less accurate.
The slide-hammer electrode E12 with teflon-
insulated pins is most commonly used for wood. As
the pins are hammered towards the core, consecu-
tive readings indicate any changes between surface
and core moisture. For core readings at least a third
of the board needs to be penetrated.
If the pins on the electrode E12 do not seem strong
enough for hammering into hard wood or strand
bamboo, use the electrode E14V with EG pins. The
E14V and the EG pins are built sturdy enough for hard pounding.
Some customers only have the electrode E14V. Measurements in wood
can be taken up to 1/2” deep with the electrode E14V.
The ability to measure a moisture gradient up to 2” deep is one import-
ant reason why customers still use pin electrodes for quality control of
wood products.
In pinless mode, you can measure only up to 3/4” deep. If high mois-
ture levels are suspected deeper down, the only option to measure
deeper than 3/4” are pin electrodes:
- Electrode E12 with DB pins can measure up to 2” deep.
- Electrode E14V, E10 or E16 with EL pins measure up to 7”.
One of the advantages of the Ligno-VersaTec is having both options pin
and pinless mode. For every application you can choose the optimum
measuring mode or use the pin and pinless mode side by side.

Measuring Building Materials
For Sheetrock (light-weight), Gypsum:
Select material setting #15 or 109
Range: 0-22% (based on oven dry weight)
- 0.1% to 0.7% is considered dry
- 0.8% to 0.9% are questionable
- 1% and higher is considered wet.
If values between 8-12% are listed for dry sheetrock,
they are based on WME percentages (Wood Moisture
Equivalent) and not on oven dry weight.
For interior, exterior and water resistant wall boards
use settings #107, 108 or 109, as listed in pocket guide.
Use inspector electrode E14V or electrode E10 for mea-
surements. Teflon-insulated pins EG and EL allow pin-pointing the source of moisture prob-
lems, differentiating between moisture in the sheetrock panels and moisture in the structure
behind the panels. Length of EL pins 0.5” to 7”.
- Electrode E14V is the ideal tool for water restoration jobs. Designed extra slim to fit into tight
places, under baseboards, around pipes, in corners, etc. The handle can be extended to reach
ceilings without a ladder or floors without crouching. You can hammer on top of the E14V to
insert pins in a precise location at a precise depth into soft and extremely hard materials.
- The electrode E10 is another option. Sturdy enough to hammer on top to insert pins.
For Concrete and Other Hard Building Materials: Select material setting #25 (105). Instant
readings can be obtained with the electrode E16. These readings do not give moisture percent-
ages. Page 19. However, problem areas of high moisture can be located instantly by comparing
readings from different areas. A chart is enclosed with the electrode E16, which lists measured
values and the target value for material acclimated to 65% relative humidity and 70oF.
-The Electrode E16 consists of two separate posts,
which makes inserting into hard materials easier.
Warning: Test results from pin or pinless meters are
not accurate enough to decide whether or not to lay a
wood floor over a concrete slab. An RH in-situ probe
test and/or a Calcium-Chloride test is recommended
by most wood floor manufacturers.
See page 19 for RH in-situ probe test in concrete with
the Ligno-VersaTec.
Comparative Measurements:
Finding settings for all building materials and the nu-
merous new engineered products is almost impossible.
To evaluate moisture conditions in these materials, comparative or relative measurements
are used. Select a setting (ref scales page 6) and take measurements (at least 2), compare the
values. Higher values represent areas of more moisture. If you had an acclimated, dry piece, you
could use that piece to establish a value for dry. Make sure the measurements were taken from
the same materials, same composition of materials and at the same measuring depth.

Monitoring using the Ligno-VersaTec
Extension cables and probes can be installed to monitor remote areas, which are other-
wise unreachable. Install probes, connect cable and leave the open cable end easily accessible.
The Ligno-VersaTec can be connected via adapter H (1), and measurements can be obtained at
any time to check for changes in moisture content.
Restoration - Leak Surveillance: An easy way to check the drying progress or to make sure
that a leak is not happening again. Depending on structure and thickness of materials, screws,
pins or wood probes can be used (3).
Wood Floors: Metal screws are placed on the underside of
floor planks or in the subfloor. Works well during acclima-
tion and for long-term monitoring after the floor is installed.
Lumber Drying - Air Drying - Storage:
Teflon-coated PK wood probes (2) and extension cables are
placed in areas, which cannot be reached otherwise Enables
moisture readings from the center of a kiln charge without
entering a hot kiln, air drying yards, storage sheds.
1 Adapter H connects split cable ends to Ligno-VersaTec.
2PK wood probes
3EG teflon-coated pins and screws
4 PK-H cable with connectors for PK probes and adapter H.
5EMC sensor: VersaTec is set up to show EMC values using
EMC sensor.
The PK wood probe and cable system has been used for
many years to monitor lumber drying, to make drying more
efficient and optimize drying schedules.
Lignomat offers everything necessary to monitor and con-
trol lumber drying from a one-cable in-kiln monitor to a ful-
lyautomatic kiln control system. Contact customer service at
800-227-2105 to find a solution for your application. Pg 18.

- If °C is set, the measuring depth is automatically indicated in mm.
- If ° F is set, the measuring depth is automatically indicated in inches (“).

Pinless Technology
The Ligno-VersaTec functions as a capacitance-type meter in
pinless (scan) mode. The measuring pads on the back of the
meter emit and pick-up low-powered electromagnetic signals.
The reading generated by the Ligno-VersaTec is an average of
the entire measuring field between the surface and the maxi-
mum depth of penetration. Moisture closer to the surface has
a greater impact on the average than the moisture closer to the
maximum depth of penetration.
Pinless measurements need to be corrected for
(1) Wood species, bamboo products and other materials.
- Settings for wood temp do not affect pinless measurements.
(2) Measuring depth is important for pinless meters.
Selectable depth for Ligno-VersaTec is 1/4” and 3/4”.
(1) Settings for the most common wood species, engineered products and building materials are
listed in the laminated pocket guide included with the meter.
Settings for unlisted wood species can be determined by using specific gravity (SG). For exam-
ple, if the SG is 0.42, the code would be 42. Values for SG can be found on the Internet: Search
for <specific gravity... > followed by wood species. The SG can also be calculated from weight,
length, width and height of sample. Page 16. For undefined species or new products call custom-
er service at 800-227-2105. If no setting is not available, Lignomat offers testing to determine
the correct code number.

Measurements
After settings have been checked /changed, press the READ key to obtain
moisture readings. The active settings appear briefly.
- If measuring pads are not in contact with any material, the lowest possible
value for the material setting appears: SCAN/Min is 4.3% for setting 160.
- If measurements are taken, the measured value (9.6%), the active setting
for material (160) and measuring depth (1/4”) are displayed.
While taking measurements: If the material is too dry to be measured, the me-
ter will show the lowest possible value indicated by SCAN/Min on the left side
of the display. If the material is too wet to be measured, the highest possible
value is indicated by SCAN/Max on the left side of the display.

To obtain accurate measurements:
Turn the meter on and place it on the test sample (for wood in the direction of
the grain). Press down lightly, holding the outer sides of the meter without touching the test
sample with your hand. It is important to put light pressure on the meter towards the test sample.
- The test sample should be big enough to cover both measuring pads. When measuring floors,
the long edge of the meter should be placed parallel to seams or grooves.
- The test sample should be at least as thick as the selected measuring depth. Page 13.
- If the surface is not smooth and flat, several measurements should be taken.
Select the highest value.
Note, all materials within the measuring field contribute to the value indicated. If the test sample
is composed of different materials, the value indicated may
not be a true moisture percentage, but may only be a refer-
ence number. It can be hard to find the correct code num-
ber for engineered or composite materials. Page 14: Find
Settings for Composite and Engineered Boards.
To make sure the material underneath the test sample is
not influencing the measurements, arrange an air space
underneath the test sample. For example: Elevate one end
of the test board to create an air space underneath the
board. If this is not possible, make sure the Ligno-Ver-
saTec is set for the correct measuring depth. Measuring
veneer, page 14.

Dual-Depth 1/4” and 3/4”
Lignomat introduced the dual-depth measuring technology many years ago. Since then, our cus-
tomers have found this feature to be very helpful for many different applications from flooring to
wood working to restoration...
Lignomat offers 4 dual-depth pinless meters:
Ligno-Scanners SD and SDM, Ligno-DuoTec BW and Lig-
no-VersaTec. All dual-depth meters from Lignomat have 2
independent sets of calibrations, one for 1/4” deep and one
for 3/4” deep.
Measuring depth is crucial for all pinless meters. Pinless
meters have a defined measuring field and pinless meters give accurate moisture percentages
only, when the entire measuring field is within the material to be measured.
Most pinless meters are calibrated for a fixed material thickness of 3/4”. Lignomats dual-depth
meters have a measuring field reaching 3/4” deep and a measuring field reaching 1/4” deep. This
allows the meters to be used for measuring thicker and thinner materials:
If test samples are thinner than the measuring depth, readings may be inaccurate:
- If not enough test material is underneath the measuring pads, values will be too low.
- If material underneath the test sample is included in the measuring field, values could be
too high.
If test samples are thicker than 1.5”, core measurements are only possible with a pin electrode.
If test samples are composed of different materials, a product specific setting maybe required to
produce accurate moisture percentages. Page 14.
Pinless Mode

-- Measuring products less than 3/4” thick: Many panel and floor products
are only 5/8” thick, which does not work well for a 3/4” measuring depth. For
example: When floor planks 5/8” thick are installed and measured with a pinless meter at 3/4”
depth, you cannot be sure that the subfloor or concrete underneath is not affecting the read-
ings. With the Ligno-VersaTec on 1/4” depth, you definitely only measure the floor planks.
--Measuring engineered products: You can find the moisture content of the thin top layer
made from hardwood by using the corresponding species setting and 1/4” depth. Using those
results, a setting can be found for the entire floor plank. Page 14.
-- 1/4” depth setting allows for checking dryness of waterbased finishes. Works great for veneer
or for measuring moisture close to the surface.
--Many building materials including drywall are less than 3/4” thick. For those materials the
1/4” depth works better and gives true measurements without including structural elements
behind the drywall.
13
Toggle between 1/4” and 3/4”: Toggling enables you to obtain 2 moisture values from
different depth levels in the same location, without moving
the meter. This is the best way to compare surface and core
moisture with the pinless measuring technology. Use the
Ligno-VersaTec with a pin electrode to measure a moisture
gradient in thicker wood.
To toggle: Place the meter on the test sample and press READ.
The active measuring depth is indicated on the left side of the
display. Hold the meter with one hand and put light pressure
on the meter to obtain accurate measurements. Use the other
hand to alternate between pressing the up and down key:
Press the up key to switch to 3/4”.
Press the down key to switch to 1/4”.

Measuring Wood
Check/change wood species setting #111-230 or 30-100.
Settings #111 to 250 are used in the Ligno-VersaTec for pin and pinless mode.
Settings #30-100 are based on the specific gravity. For example, for a specific gravity of 0.42,
choose #42. All pinless meters from Lignomat including the Ligno-VersaTec are programmed for
settings #30-100.
Check/change depth setting according to the thickness of the wood. Page 13: Dual-Depth.
To measure, press the READ key and place the meter on the wood in the direction of the grain.
Measuring range for wood is 5%*to 60%**.
* The lowest measurable moisture value depends on the specific gravity of the wood species.
To find the lowest measurable moisture value for a species setting, hold the meter in the air
and press READ. The lowest values for hardwoods are usually lower than 5%. The lowest
values for softwoods are usually higher than 5%. For example, the lowest value for setting
#160 is 4.3%.
** Measurements above fiber saturation (25-30%) are less accurate.

Measuring Bamboo:Lignomat developed a unique set of calibrations for
different types of bamboo floors and engineered bamboo products, settings
#11-24. The values indicated by the Ligno-VersaTec are WME percentages. WME is the wood
moisture equivalent. The following example shows what WME means: If bamboo is acclimated to
ambient condition of 42% relative humidity, the Ligno-VersaTec on the correct bamboo setting
indicates 8%. If wood is acclimated to the same 42% relative humidity, the wood moisture con-
tent is also 8%. EMC chart page 17.
Bamboo products are usually less than 3/4” thick, therefore the measuring depth is limite to 1/4”.
Make sure that the selected depth is 1/4”, when using settings #11-24. When the meter is set for a
3/4” measuring depth, measurements are not defined and the meter will toggle between PIN and
SCAN. Change depth to 1/4” and if you have the newest software, the meter will work. If you have
an older software, the meter may still not work, contact Lignomat 800-227-2105 for an up-date
on your meter. (At the time the meter was sold, the active setting had not been defined yet.)
Measuring Veneer: We recommend placing a lightweight material such as styrofoam under-
neath the test sample when measuring veneer or other thin materials. It not only prevents inac-
curate readings, but also helps to create a flat measuring platform. To obtain accurate readings
for very thin veneer it may be necessary to make a stack of several sheets.
You can also find a setting for single veneer sheets. See below, start with step 2, if you have a
veneer sheet with a known moisture content. Otherwise, start with step 1b, if you have a sheet
acclimated to a known relative humidity.

Find Settings for Composite Materials and Engineered Boards
Follow steps 1 and 2 to find settings for products not listed on the species card.
For best results, the test sample should be acclimated to a uniform moisture content.
Step 1: Determine the moisture content (MC value) of the test sample using 1a) or 1b).
1a) If the top layer is wood, find the MC value by taking readings. Set the meter to the
wood species of the top layer at 1/4” depth, even if the top layer is thinner than 1/4”.
1b) If the top layer is not wood or the product is less than 1/4” thick (veneer), the test sample has
to be well acclimated in a known relative humidity. Then you can find the MC value in the EMC
chart. Moisture measurements with the meter are not needed. Look up the relative humidity and
find the corresponding EMC value. For a test sample acclimated in 40-50% rel. humidity, the MC
value is 8.5% . Page 18.
Step 2: Determine the new setting using the MC value found in step 1.
Select setting # 50 and 3/4” depth. Use 1/4” depth for test samples less than 3/4” thick. Then,
take a reading.
--If the reading is lower than the MC value found in step 1, choose a setting lower than 50.
--If the reading is higher than the MC value found in step 1, choose a setting higher than 50.
Then, take another measurement. Change the setting, until you get a reading close to the MC
value determined in step 1.
The new-found setting can be used in the future for the same type of product.
When dealing with engineered floors, the thickness of the top layer and the composition of the core
have an impact on the moisture value. When a setting has been found, this setting should only be
used for the exact same panels or floor boards.

Measuring Building Materials:
Select the correct material setting. If the material is not listed on the
laminated species card, use one of the reference scales:
- for laminates and composites made from wood ...................................... code #0
- for concrete and building materials with a similar specific gravity.......... code #25 (105)
- for drywall and building materials with a similar specific gravity............ code #15 (109)
- for building materials in between concrete and drywall .......................... code #10
Measuring with a reference scale is best done when a dry sample is available. Measure the dry
sample and use the number as base value for comparing readings. Even if
no dry sample is available, higher values indicate more moisture.
Note, no % sign. Reference scales do not indicate moisture percentages.
When taking measurements, make sure the surface is clean. If surfaces are uneven, try different
orientations of the meter and use the highest value.
Water damage restoration: Pin and pinless measurements are crucial when tracking mois-
ture problems. The Ligno-VersaTec can scan large areas quickly up to 3/4” deep. If the problem
is buried deeper down, pin measurements with electrode E14V and long EL pins are the only
option to reach the problem areas. In addition, the electrode E14V can measure areas a pinless
meter cannot reach such as corners, around pipes and window sills, under base boards, etc.
Sheetrock: Setting #15 (Range: 0-2.0%). The indicated moisture percentages are based on dry
weight. Meters indicating moisture values of 8-12% for dry sheetrock, use scales based on WME,
wood moisture equivalent (EMC chart page 17).
- Dry sheetrock ranges from 0.1% to 0.7%.
- Values for 0.8% and 0.9% are questionable.
- Any value 1% and higher is considered wet.
Sheetrock is often thinner than 3/4”. The Ligno-VersaTec, a dual-depth pinless meter has 1/4”
measuring depth, which is ideal to measure thinner sheetrock. If the sheetrock is installed, the
1/4” depth gives true moisture percentages, without including material behind the sheetrock.
Concrete: Setting #25 (105) (Range: 0-99.9). Moisture readings are given on a relative scale
comparable to relative humidity readings in concrete. Readings indicate high and low moisture
levels, but not moisture percentages of concrete. The measuring depth is limited to 3/4” deep.
Measurements with pinless meters provide a preliminary evaluation of moisture conditions.
Moisture meters are not able to indicate moisture percentages in concrete (ASTM F2659).
Concrete mixtures, additives and agregates affect moisture measurements. Page 19.
Warning: Test results from pin or pinless meters should not be used to decide whether or not to
lay a wood floor over a concrete slab. An RH in-depth probe test and/or a Calcium-Chloride test
is recommended by most wood floor manufacturers.
Follow the floor manufacturer’s installation instructions and perform the required
testing to guarantee the manufacturer’s warranty.
Comparative Measurements:
Finding settings for all building materials and the numerous new engineered products is almost
impossible.... continued page 9.

Wood Floor Installation:
Wood moisture meters and thermo-hygrometers are essential tools for floor
installers. Adding Lignomat’s humidity probe RH BluePeg allows using the VersaTec as pin/pin-
less meter and as precision thermo-hygrometer. Page 18. Whenever possible, wood moisture and
relative humidity should be measured.
First: Take measurements when the floor is delivered, to make sure the floor is dry.
Next: Take measurements (moisture and RH) before, during and after acclimation. Mark sample
boards and take readings of the same spot repeatedly.
Last: The moisture content of a floor should be docu-
mented at the time the customer signs offon the instal-
lation. Select moisture sensitive areas, under windows,
inside doors, by the refrigerator and take readings with
both depth levels and document the measurements with
moisture content, species setting, measuring depth and
location. Take a photo to pinpoint the location. Use the
VersaTec with the RH BluePeg probe to take relative
humidity and temperature measurements.
Keeping track of moisture conditions may in the end protect you from unwarranted claims and help
find the cause of a problem. If you ever have to go back to check out a complaint, you can measure
the same areas again and compare with the original measurements. The dual-depth readings can
indicate if moisture was absorbed from the down-side of the floor or from the up-side of the floor.
See EMC chart on page 18 for equilibrium moisture contents and the corresponding relative hu-
midity and temperature. If EMC and MC are kept in close range, wood floors are absolutely stable.

Calculating Specific Gravity
The settings #30-100 correct for different wood species, the numbers correspond with the spe-
cific gravity. If the specific gravity is 0.42, the meter should be set to #42 in pinless mode. The
specific gravity can be found on the Internet by entering <specific gravity ....> followed by the
wood species. Specific gravity can also be calculated as dry weight by volume:
Specific Gravity = Dry Weight x 1.73 (enter Dry Weight in ounces)
Length x Width x Heights (enter Width, Heights, Length in inches)
Specific Gravity = Dry Weight (enter Dry Weight in gram)
Length x Width x Heights (enter Width, Heights, Length in centimeters)
The settings for the most common wood species and materials are listed on the laminated pocket
guide included with the meter. For unlisted wood species you can find the specific gravity on the
Internet or calculate the specific gravity using the formulas listed above. If no listing can be found,
call customer service at 800-227-2105. If no listing is available, Lignomat offers testing to determine
the correct setting.

Relative Humidity, Wood Moisture and EMC Chart
The moisture content of wood and the relative humidity of the surrounding air determine wheth-
er of not wood is dimensionally stable and whether or not wood is susceptible to mold growth.
Recommended ambient conditions in buildings are 30-50% relative humidity at 60-80°F, with-
in this range, the amount of expansion and contraction of wood floors and furnishings at 6-9%
moisture content is limited. (Table from US Dept of Agriculture)
Example: For a relative humidity of 35% and a temperature of 70°F, the EMC is 6.9%. A wood floor at 6.9%
moisture content is stable, when MC and EMC are the same.
Dimensional Stability of Wood
Wood moisture and relative humidity are crucial factors for dimensional stability of wood. Use
the Ligno-VersaTec to measure both. If wood shrinks, warps, cups, checks or delaminates, it
always has to do with changes in wood moisture and/or relative humidity. No shrinking and
warping occurs, when an equilibrium with the surrounding air has already been reached.
Predictions and Explanations: Measure relative humidity, temperature and moisture con-
tent. Compare the measured values with the EMC chart above to predict, if wood is stable
-- A hardwood floor shows gaps from shrinking. The moisture content at the present time
measures 6.2% and the rel. humidity is at 30%. The only explanation for the gapping is, that
the floor was installed at a higher moisture content. Once exposed to the dry air, the floor
driedout and the gapping occurred.
-- If a dry floor with a perfect moisture content of 6.2% is exposed for a long time to air with a
relative humidity of 60% at 70°F, it can be predicted that the floor will absorb moisture until
11% has been reached. Depending on the wood species, a 5% increase in moisture content can
be accompanied by a substantial amount of expansion.
No more surprises! Use the EMC chart and your Ligno-VersaTec to predict problems. The
chart is also helpful to explain to your customers, why relative humidity in their home matters.
Mold in Building Materials
Mold has become a great concern in the building and restoration industry. Mold can grow
almost anywhere, if the relative humidity rises above 80% and temperatures are moderate (not
screaming hot or icy cold). The critical moisture percentage is above 16% for mold growth in
wood. This critical moisture percentage can be exceeded, when water infiltrates a structure by
leaks, floods and broken pipes or when buildings are not sealed properly. Repair work is neces-
sary to avoid lasting damage.
The Ligno-VersaTec can measure moisture content and relative humidity. Compare both values.
Establish the extent of damage and monitor progress until all repairs are done.

Monitoring RH and MC with Data Loggers
The Ligno-VersaTec can be used as an accurate and reliable thermo-
hygrometer. However, a thermo-hygrometer provides only at-the-moment
measurements. For monitoring over time, we offer the BL 2 data logger.
The BL2 data logger comes with the precision RH BluePeg probe. 32000
Data sets can be sampled in time intervals 30 seconds to 24 hours. Audible
alarms can be set. A great watchdog for restoration work, floor installation,
job-site surveillance, long term recordings of storage facilities.
The BL2 with MC Tracker allows recording wood moisture and relative
humidity. It is like continuously taking readings with 3 wood moisture
meters and 1 thermo-hygrometer.
Lignomat also offers wireless transmitters for measuring moisture, humid-
ity, external and internal temperature. Data is at any time available at a PC
and can be viewed from anywhere remotely.

RH Technology
The Ligno-VersaTec functions as RH meter or thermo-hygrometer, when the RH BluePeg probe
is connected. The RH BluePeg probe uses a single micro-chip factory calibrated to NIST standard.
Applications include:
- measuring ambient air conditions
- in-situ moisture test in concrete, next page.
Specification of RH BluePeg Probe:
Relative Humidity: Range 0% to 99.9%
±2% for 10% to 90%, ±3% for below 10% and above 90%
Temperature: Range 5°F to 160°F (-15°C to 70°C)
±0.5°F for 32°F to 120°F (±0.3°C for 0°C to 50°C, )
±1°F for below 32°F, over 120°F (±0.5°C for <0°C and > 50°C )
Measuring Range for DPT: -17.8°F to 160°F (0°C to 70°C)
Measuring Range for GPP: 0-99.9
Resolution for entire range all values: 0.1°F (0.1°C)
Size or RH BluePeg probe: Ø 0.5” (1.27cm), L 1.35” (3.8cm),
Connection: 3.5 mm stereo jack or stereo cable up to 50 ft long
Measurements
As soon as the RH BluePeg probe is connected, the Ligno-VersaTec automatically switches into
RH mode and indicates RH values. All values for RH, temperature, Dew Point and GPP can be
obtained by first pressing READ, then HOLD and then using the up or down keys to scroll between
RH/T/DP/GPP. The number sign “#” and the letter “H” toggle, while the HOLD function is active.
RH: relative humidity
T: ambient temperature
DewP: dew point temperature
GPP: grains per pound
#: RH probes have individual 3-digit numbers
RH Mode

The in-situ RH test gives the most reliable results for concrete moisture
testing to determine, if a floor covering should be installed or adhesive
or epoxy can be applied. See separate instructions for in-situ probe test
with RH BluePeg probes. Instructions are available online or as booklet
from Lignomat (800-227-2105).
ASTM standard F2170 describes equipment and procedure. The duration
of the test is now 24 hours, a time limit set by the ASTM standard. All of
Lignomat’s RH parts comply with the latest standard F2170.
The in-situ RH concrete test has gained recognition over the past few
years. Many floor covering manufacturers have added the RH concrete
test to their warrwanty requirements. Check the floor manufacturers
manual to guarantee the manufacturer’s warranty.
If you own a Ligno-VersaTec the following accessories are needed to
perform in-situ RH moisture testing in concrete:
RH Probes, RH Sleeves, RH Cable with cable-end-cover
Also needed drill, brush, vacuum attachment.
Measuring Concrete Moisture with the Ligno-VersaTec
The Ligno-VersaTec offers three different technologies to measure moisture in concrete.
Pin: Adding the Electrode E16 allows measuring up to 7” deep into a concrete slab. This was the
preferred method several years ago. However, it has been proven, that the results are only qualita-
tive measurements. Only high and low moisture areas can be found.
Pinless: Using the pinless mode of the Ligno-VersaTec, the measuring depth is limited to 3/4”.
Within that 3/4” depth high and low moisture levels can be determined. The 3/4” depth does not
include the middle section of the slab and therefore cannot be used to determine whether or not a
resilient floor covering can be installed. A correct percent value is hard to establish because of the
difference in concrete mixtures. High and low moisture areas can always be found.
In-situ RH testing: Use the RH mode of the Ligno-VersaTec with the RH BluePeg probes, and
measure the relative humidity and temperature inside a hole in the concrete. The relative humidity
values obtained from inside the hole are directly related to the moisture condition of the concrete.
Why RH testing at 40% gives the most reliable results: Moisture distribution with-
in an open concrete slab is often not uniform, especially when the slab has not dried completely or
when the slab is on grade. The surface shows low moisture levels, whereas higher moisture levels
are found in the middle of the slab or towards the bottom (especially for slabs on grade). Once the
open concrete slab is covered by the floor covering, moisture will be pulled up from the bottom
towards the drier surface until an even moisture distribution has been reached. The increase in
moisture close to the surface can cause problems with epoxy, adhesives and floor coverings.
It has been shown that moisture measurements taken at 40% of the slab thickness give the same
results when the slab is open and later-on when the slab is covered. Therefore, test results from
the open slab at 40% depth can be used to predict what the moisture content will be once the slab
is closed. This allows manufacturers of adhesives, epoxy and floor coverings to set a permissible
range for their products. If the slab is not on grade, the ASTM standard F2170 allows testing at
20% depth.

Function and Calibration Check for Pin and Pinless Mode
All pin and pinless meters from Lignomat including the Ligno-VersaTec are built with high qual-
ity components, micro-processor based, to guarantee stable calibrations for many years of usage.
All meters from Lignomat internally check and if necessary adjust the calibration before each
reading, therefore the meters are not set up to be re-calibrated manually by the user.
Before the battery is drained completely and the meter will not give any more
values, a warning sign appears in the middle of the display, indicating the
battery should be replaced soon.
Function Test: Pin and pinless measurement functions can be tested for open and closed circuit
connections manually.
Calibration Test: Pin and pinless measurements can be tested for calibration accuracy with check
blocks provided by Lignomat. Using the calibration check blocks confirms that all connections
function properly:
- in pinless mode from the measuring pad to the display.
- in pin mode from the tip of the pins to the display (including pins, hand probe or electrode,
cable, meter and all connections)
For sensitive testing we recommend using the check block before and after a test series.
Pin Mode
Manual function check: Step 1 and Step 2
Calibration check: Step 3
Step 1: Short circuit test: Set the meter to pin mode, select setting #103 and a wood temperature
of 70°F. First check the meter only. Press the READ key and a low moisture value of 5.0% should
be indicated with PIN/Min on the left side of the display. Next connect the cable. Press the READ
key again and a value of 5% should be indicated. Last check the meter with cable and electrode
(do not touch the electrode pins).
Your equipment passed the open circuit check if the 5% value is indicated every time. If the 5%
value cannot be confirmed at the first check, the meter is defective, at the second check the cable
is defective, at the third check the electrode is defective.
Step 2: Function test: Connect meter, cable and electrode. When the READ key is pressed and
the metal tips of both pins are touched with two fingers, a reading should be higher than 12%. If
that is not the case, disconnect the electrode (electrode is defective). To check the cable, put your
thumb on the open cable end. The cable is ok, if a reading higher than 12% is indicated.
Step 3: Lignomat offers an external calibration check block TP.
The block is used to confirm the calibration of all Lignomat pin
meters. Connect meter, cable and electrode. Set the meter to pin
mode. Select code # 103 and a wood temperature of 70°F. Place
pins on screws for a value of 12% and 20%. Test confirms that
meter, electrode and cable work, and the calibration is correct.
Note: Step 3 can be done instead of Step 2.
However, Step 1 should always be performed.
If steps 1, 2 or 3 fail either the battery needs to be replaced or
the electrode, the cable or the meter are defective.
