Lignomat mini-Ligno DX/C User manual

User Instructions for all mini-Lignos
Lignomat USA, LTD. 14345 NE Morris Ct, Portland OR USA, Tel: [phone], FAX: [phone], e-mail: [email protected]
Before taking measurements with a mini-Ligno, the
protective cap over the pins has to be removed
and can be placed on the other end of the meter
for easy pin insertion. As soon as the pins are
pushed into the wood, the on-off switch between
the pins is depressed. Red LEDs indicate wood
moisture in percent for a wood temperature of
700F(200C). For higher or lower wood tempe-
ratures see correction table on page 6
All Lignomat meters internally check and adjust the
calibration. Therefore manual checks and
recalibration is not necessary and not possible.
Wood Group Corrections: All mini-Lignos are
equipped with built-in wood group corrections. A
chart for wood species and corresponding wood
group settings is included with each mini-Ligno.
Wood species with similar electrical properties are
in the same wood group. For unlisted wood species
Lignomat offers free of charge testing to determine
the wood group.
Core Measurements: For core measurements at
least one third of the wood needs to be penetrated.
The longer mini-Ligno pins reach 7/16”(10mm)
deep into a board. For core measurements in over
5/4” (30mm) lumber, make a fresh cut. Measure
the end grain close to the surface and at the core.
If it is not feasible to cut the board, the core of the
wood can only be reached with the external Electrode
E12 and any mini-Ligno C-model.
Battery: One 9-Volt Battery. If the LED lights get
dim or step 1 and 2 described under “Performance
Test” fail, remove screw on back cover, open-up
into 2 halves and replace battery.
Pins: All mini-Lignos come with 2 sets of pins #MA for
a measuring depth of 3/16” (5mm) and #MB for
7/16” (10mm). To exchange pins, remove screw on
back cover, open-up into 2 halves. The longer pins
are stored inside the back cover on either side of the
indentations for the pins. Remove and replace pins.
Electro-Magnetic Interference and Static
Electricity: If you measure close to computers,
power tools or electrical wires, several LED lights
may be on or the moisture readings jump. To avoid
the interference, take readings in a different location.
The wood, the meter and the person holding the
meter should not move while taking readings.
Performance Tests:
Step 1: When the on-off switch is pressed by hand
without touching the pins, the lowest moisture value
is indicated: for mini-Ligno DX or DX/C: 5%
for mini-Ligno, mini-Ligno C, E/D, S/D or S/DC: 6%.
Step 2: When the on-off switch is depressed by
hand and both pins are touched with two fingers at
the same time at least 12% should be indicated.
Step 3 optional: Lignomat offers an external
testblock to check calibration and operation of any
Lignomat pin meter, including cable and electrode.
If steps 1, 2 or 3 fail either the battery needs to be
replaced or the meter is defective.

Mini-Lignos MD/C, S/DC, DX/C have two integral pins
and a cable connection built-in. To measure connect
cable ends into the
inserts besides the
pins. Depress on-off
switch between pins by
hand to activate meter.

All mini-Lignos come with a two-year warranty,
accessories have a one-year warranty,
pins and batteries are excluded.

1.6 Electrodes for mini C-Models
E12 Electrode and mini-BNC Cable is for
measure- ments up to 2” (50mm) deep in wood
and soft building materials (drywall, gypsum,
plaster, etc.) Allows comparing surface and core
moisture.
E14M Inspector Electrode: in-Hand probe
includes cable, EG Pins, teflon-coated. Measures
hard to reach places easily, because of its slim
shape. Extendable handle. Optional EL Pins 7”.
E16 Specialty/Concrete Electrode and
mini-E16 Cable for measurements of concrete
and other hard building materials. Standard pins
5/8” (15mm). Optional add EL Pins 7” (17.5cm)
1.7 In-kiln - remote
In-Kiln PK Probes and
mini-PK Cables are used
for measure-ments of
stacked lumber in kilns,
air-drying yards or
warehouses. PK Probes
are available to measure
up to 2.75” deep. Cables
can be upon request up
to 50ft (15m) long.
Non-Kiln Applications
Lignomat’s cable system works well for monitoring inaccessible areas
(underside of floor planks, structural components, behind drywall,
roof trusses, etc.)
Teflon coated pins for a measuring depth of 3/4” and 7” are also
available. For those applications cables with loops are available.

1.4 mini-Ligno DX and DX/C
Lignomat
For example at 65% relative humidity and 700F (200C)
drywall measures 0.7%, the corresponding WME
on wood group 2 is 11%.
Setting 0Setting 0
Setting 0Setting 0
Setting 0 is a Reference Scale (0-99) for
comparative readings in building materials. For
ranges see graph on page 1.3. We recommend
measuring a dry sample to establish a base value for
dry. Compare readings in test material to the base
value. For hard building materials such as concrete,
brick or stone, we recommend DX/C plus Electrode
E14C or Electrode E16 with EC pins.
To investigate hard to reach problem areas we
recommend the DX/C with the Electrode E14C. To
take core measurements in wood we recom-mend
the DX/C with the Electrode E12.
Measuring Concrete and other Non-Wood
Building Materials with Electrode E14C and EC
or EL pins
For surface readings insert the pins 1/8” (3mm).
For depth readings drill 2 holes about 3/16” (5mm)
wide and approximately as deep as you want to
measure (up to 7” with EL pins). Insert pins an
additional 1/8” (3mm) so that the shanks of the pins
are not touching the concrete. Be sure the contact
area does not change from test to test. For deeper
readings you can use regular nails and touch nail
head with mini-Ligno pins.
For more accurate evaluation of concrete moisture
use Lignomats in-situ RH BluePeg system.
Measuring Range:
4.8-65% dependent
on wood group.
Red numbers indicate
wood moisture in %.
For moisture values
above the measuring
range, the highest
moisture value for the
chosen wood group is
flashing. A blinking
decimal point
indicates the lowest
readings for the
chosen wood group.
Wood Group Settings: The blue laminated card lists
domestic and tropical species and corresponding
wood group settings. Click on-off switch twice to
check/change settings. Yellow LEDs indicate
settings: 1-40 for wood (0 and 41 is for building
materials). Click on-off switch again to change
setting. Check/Change Mode is only accessible when
meter is off. If a wood species is not listed on the
laminated blue card, contact customer service at
800-227-2105.

If using the correction chart is too time
consuming, Lignomat offers moisture
meters with built-in wood temperature
corrections. The following meters indicate
moisture values internally corrected for
chosen wood group and chosen wood
temperature: mini-Master HT or HTC,
Lignometer KF or KC,
Ligno-VersaTec.

Wood Temperature Correction Chart
Lignomat USA, LTD. 14345 NE Morris Ct, Portland OR USA, Tel: [phone], FAX: [phone], e-mail: [email protected]
* The mini-Lignos are calibrated for a wood temperature of 70oF (20oC)
For wood temperature over 80oF and under 60oF we recommend using this chart.
