OPERATING INSTRUCTIONS
-User Guide-
This guide provides step-by-step instructions on powering up, using and powering down the
meter.
NAVIGATION:
The meter uses an on-screen, menu-driven approach to navigate through the meter features,
allowing for an intuitive understanding of keypad functions. Each screen presents the user with a
number of selectable options. One of the options is always selected and the user can move
(navigate) the selection to any other available option. The keypad is aimed at providing
navigational control, and not at accessing specific features. There are four directional keys
aligned intuitively around a middle (fifth) key (see Figure 1): Above (UP), below (DOWN), to the
right (RIGHT) and to the left (LEFT). The middle key is used to SELECT the option highlighted on
the screen. For purposes of this owner’s manual, the five keys will be referred to as
and SELECT.
INSTALLING THE BATTERY:
The battery compartment is located on the underside of the case, at the bottom of the handle.
1. Open the battery compartment by sliding the lid back while pressing on the release indent.
2. Ensure correct polarity, and push the battery in flush with the bottom board until the
connectors snap together on both sides. Use only Duracell or Energizer alkaline 9V.
3.
4. Replace the battery compartment lid.
LOW BATTERY:
The meter features a battery status monitor, designed to warn the user as well as protect
measurement accuracy from impending battery failure conditions. The battery warning is
triggered by either continuous or temporary low voltage conditions. Visible (a battery icon on the
top right side of the display) and audible (buzzer warble) indicators accompany a battery warning.
Once a permanent low battery condition is detected, all measurement functions are disabled. The
battery should be replaced immediately. If the battery reaches critical levels, the meter will refuse
to stay on at power-up. This gradual warning system is intended to provide the user advanced
battery status notice and give ample time for replacement before operational limitations occur.
NOTE: Current meter settings are not lost during battery replacement or low battery conditions.

3. Push the contact pins into material to be tested. Any Delmhorst electrode may also be
used in WOOD mode by simply attaching it to the connector next to the contact pins.
4. The unit will read %MC on a wood scale between 6% and 60%. At elevated wood
temperatures, a reading above 30 percent is valid if the temperature-corrected reading
falls below 30 percent. Otherwise, these high readings provide relative comparisons,
indicating that the material is taking on or losing moisture.
5. To hold a reading on-screen, press the HOLD (SELECT) KEY. Press the HOLD
(SELECT) KEY again to return to measuring mode.
6. Use the key to highlight EXIT. Then, use the SELECT key to return to the MAIN
MENU when finished.
NOTE:The TechCheck Plus is calibrated to give %MC readings on Douglas Fir. If you are
taking readings on other species of wood, refer to the species correction chart.
TO TAKE DRYWALL READINGS:
1. From the Main Menu, use the key to highlight DRYWALL. Then, use the SELECT
key to enter the pin mode.
2. The meter will display the DRYWALL screen, as shown below:

TAKING A READING –PRACTICAL APPLICATIONS
The following application notes are intended for use with the meter in PIN
MODE except where otherwise indicated.
TESTING WOOD:
The integral contact pins (5/16in penetration) on top of the meter are best for wood up to 1-
1/2inches (6/4) or drywall. Use the 26-ES electrode on hard materials, wood over 2 inches thick,
or for any application where using the insulated pins are needed for best accuracy. The 22-E
with 1/2in non-insulated pins is also an excellent option for wood or drywall. Mount the electrode
directly to the external connector at the top of the meter.
To take a wood reading, align the contact pins parallel to the grain and push them to their
full penetration into the wood, if possible. Insulated pins read only at the tip and can be
driven to the desired depth.
Press the SELECT button and read the moisture content on the meter scale. The meter
displays the %MC for two seconds.
Apply species and temperature corrections if necessary for best accuracy. Refer to charts
at the back of the manual.
PAINT FAILURE AND MOISTURE
Moisture is by far the most frequent cause of paint failure. The key to preventing paint failure is to
insure that moisture is not absorbed through the wood to the back of the paint film. So, in order to
insure quality paint jobs, wood must remain dry after the application of paint.
Outdoor wood can be safely painted without danger of peeling if the %MC is 15% or less. In drier
climates, the maximum reading should be 10% to 11%. Indoor wood should be between 7% and
8% prior to painting.
The following conditions may cause high moisture content in wood:
Leaky gutters and down spouts
Leaky pipes or condensation on cold water lines in attic or hollow walls
Faulty flashing around windows, doors and where porch and dormer roofs meet sidings
End-grain wood that is not sealed with paint at all joints around windows, corners, and butt
joints
Porch columns that do not have good drainage and ventilation where they rest on porch
floors
Siding or any other wood that is in contact with the ground may absorb moisture
Siding and shingles without sufficient lap so that water is forced up through cracks by wind
pressure
Ice dams
Condensation of vapor within hollow walls
EIFS (Exterior Insulation & Finish Systems)
Moisture intrusion problems in EIFS (also known as synthetic stucco) stem from leaking window
frames, improper use of or lack of sealant, and faulty installation of flashing.

If you suspect a problem take a visual inspection. Look for gaps around windows, doors, air
conditioning units, light fixtures, hose bibs, dryer vents and other areas of potential penetration.
Also look for visible signs of water damage. If you feel a problem exists, use the 21-E electrode.
This electrode uses the 608 - (4") insulated pins or 608/001 (7”) insulated pins.
Procedure:
Drill two 1/4" holes about ¾” apart at an upward 45° angle.
Push the 21-E Electrode into the holes through the polystyrene and into the substrate and
read the moisture content on the meter scale. When used on materials other than wood, the
meter’s PIN mode will give relative readings only, not %MC. The numbers displayed
represent the relative dryness or wetness of the material on a scale of 6 to 60. In order to
accurately interpret your readings, first establish a baseline reading by taking a reading in an
area you know to be unaffected, then take a reading in the affected area and compare the
two readings.
TESTING CONCRETE SLABS FOR FLOORING APPLICATIONS
Moisture meters are an effective tool to check comparative moisture conditions in concrete slabs.
They can tell you where there may be excess moisture and help determine if you need to conduct
further testing, and identify specific areas on which that testing should be performed. Meters do
not provide quantitative results as a basis for acceptance of a slab for installation of moisture-
sensitive flooring systems. ASTM Test Method F2170 (RH using in-situ probes), F1869 (calcium
chloride), and F2420 (RH on surface using insulated hood) provide quantitative information for
determining if moisture levels are within specific limits.
It is important to test both the surface and mid-section of the slab, especially if the slab is on or
below grade. This will help determine if there is continuous moisture migration toward the
surface. If this condition exists, the moisture movement may be so slow that once it reaches the
surface, moisture evaporates and causes a “dry” reading when a surface test is made.
However, if a sub-surface test is made, the meter may read “wet” indicating the presence of
moisture. When the slab is covered and the upward movement of moisture continues, moisture
will move into a hygroscopic (wood) floor, or build-up pressure under a non-breathing synthetic
floor, causing delamination.
Taking a surface reading:
USING PIN MODE –WOOD scale
Drive two hardened-steel masonry nails about 3/4" apart into the finish coat of
concrete floor. Drive them about 1/8" deep so they make firm contact with the concrete
and do not move when touched.
Touch the nails with the contact pins. If the meter reads less than “28”, the surface is
dry. However, sub-surface tests should be made to verify if the slab is dry throughout.

USING SCAN MODE
First establish a benchmark by takingreadings in areas that you know are dry, or
acceptable.
www. .com [e-mail]1.800.561.8187

Copyright 2009, Delmhorst Instrument Co.
Page 11 of 35
Take readings on areas that are wet. These “dry to wet” readings can be used as
reference points against which subsequent readings are compared. Understanding the
meter’s behavior on a particular material, along with these comparative readings, your
experience, and visual clues will all help determine the overall condition. All readings
should be evaluated in the light of factors such as type of paint, type of construction, and
climatic conditions.
Subsurface test:
Drill two 1/4" holes, 3/4" apart and 1/2" to 2" deep.
Drive the masonry nails into the bottom of the holes and make the tests as described
above. Nails must not touch sides of drilled holes.
If the meter still indicates a “dry” condition, the floor is ready for covering. Tests should
be made at several points, especially when the slab is thick (4” or more) and air
circulation is poor. Make tests only in newly drilled holes.
Even readings in the “wet” range can indicate relatively low moisture content in Concrete.
For example, readings in the “28 - 35” range indicate approximately 2% to 4% moisture
content.
When evaluating a slab for readiness, always consider its age, thickness, whether the
slab is on grade or suspended, whether a vapor barrier is present and the drainage
condition of the ground.
TESTING INSULATION:
Set the meter to the Wood scale. Remember that when used on materials other than wood,
the meter’s PIN mode will give relative readings only. Establish a baseline reading by taking a
reading in an area you know to be unaffected, then take a reading in the affected area and
compare the two readings.
To take a reading, attach a 21-E electrode with 4” insulated contact pins to the meter. Push
the contact pins through the drywall into the insulation behind it.
Press the SELECT button and read the relative moisture level on the meter scale. The
meter displays the “relative” moisture level for two seconds.
TESTING DRYWALL
USING PIN MODE
Set the meter scale to Drywall
To take a reading, push the contact pins into the drywall to their full penetration, if possible.
Press the SELECT button and read the moisture content on the meter scale. The meter
displays the %MC for two seconds.

Note:
Readings between 0.1% and 0.5% indicate a sufficiently dry moisture level. Readings between
0.5% and 1% indicate a borderline situation. Readings greater than 1% indicate material that is
too wet for painting or wallpaper. A reading above 1% also indicates enough moisture present to
allow mold growth to occur but only if other factors are also present such as a high RH level and
food source.
USING SCAN MODE
You can also take a reference reading on drywall using the meter’s SCAN mode. To take a
reading, firmly press the back of the meter onto the material to be tested while in SCAN mode.
This will display a relative reading that ranges between 0 and 300. Remember to establish a
baseline reading by taking a reading in an area you know to be unaffected, then take a reading in
the affected area and compare the two readings.

CARE OF YOUR METER
Store your meter in a clean, dry place. The protective carrying case provided is an ideal
storage place when the meter is not in use. If the meter has been left in a hot or cold
environment overnight or for an extended period, the calibration of the pinless mode may be
adversely affected. Under these conditions, allow the meter to acclimate to the temperature
conditions in which it will be used for minimum 1-2 hours, or as long as possible.
Change contact pins as needed. Keep pin retainers hand tightened.
Clean the meter and contact pins with any biodegradable cleaner. Use the cleaner sparingly
and on external parts only. Keep cleaner out of the external connector.
Remove the battery if the meter will not to be used for one month or longer.

Moisture content values shown shaded are only qualitative, since they are above the fiber
saturation point.
The temperature correction values shown in this chart have been rounded for easy reference. If
you desire a reading closer to your temperature for greater accuracy we have included a
temperature correction slide rule. This will give you correction values for your meter readings in
small gradual increment.
