Cautions
The electrode measurement pins are extremely sharp. Use care when handling this instrument.
Cover the pins with the protective cap when the instrument is not in use
This device is not a toy and must not reach children’s hands. It contains hazardous objects as well
as small parts that the children could swallow. In case a child swallows any of them, please
contact a physician immediately
Do not leave the battery and packing material lying around unattended; they can be dangerous for
children if they use them as toys
In case the device is going to be unused for an extended period of time, remove the battery to
prevent them from draining
Expired or damaged batteries can cause cauterization on contact with the skin. Always, therefore,
use suitable hand gloves in such cases
See that the battery is not short-circuited. Do not throw the battery into a fire

Operation
1. Remove the protective cap to expose the electrode pins.
2. The meter automatically switches ON when the cap is removed.
3. The meter automatically shuts OFF when the cap is replaced.
4. To conserve battery life, the meter automatically shuts off after 15 minutes when the cap is
left off. To revive the meter after an Auto Power OFF, simply press the yellow cut-off switch
momentarily.
5. Slide material selection switch to read wood moisture or building moisture.
6. Carefully push the electrode pins as far as possible into the material under test. Note that
the pins should be inserted into wood perpendicular to the wood’s fiber structure.
7. Take several readings in several locations on the material for the best representation of the
amount of moisture present.
8. Read the measurement values on the display.
9. Replace the protective cap when finished.
Reading the Display
1. The LCD display has two scales
2. The wood scale indicates wood moisture from 6 to 44%.
3. The building materials scale indicates moisture content
from 0.2 to 2.4%. To calculate the Wood % equivalent
multiple the building material reading by 20.
(example – 0.6% building x 20 = 12 %WME).
4. A continuous line indicates an even number. A dotted line
indicates on odd number.
5. The battery icon appears when the batteries are weak and
require replacement.
Auto Power OFF
With the protective cap removed, the meter will turn off after 15
minutes to conserve battery life. Press the yellow cutoff switch
momentarily to restart the meter. Always secure the protective
cap when the instrument is not in use.
Instrument Measurement Verification check
1. With the meter wood moisture position, touch the electrode test pins to the two test points 1
and 2 at the top of the protective cap labeled ‘T’.
2. With the unit on and the electrode pins touching the ‘T’ test points, the meter should read
27% ±2%. If not, the meter may require repair.
Battery Check
1. With the meter wood moisture position, touch the electrode test pins
to the two test points 3 and 4 at the top of the protective cap labeled
‘B’ (see diagram).
2. With the unit on and the electrode pins touching the ‘B’ test points, the meter should read >
44%±2% on the wood moisture scale. If not, replace the batteries.
CAUTION: The electrode measurement pins are extremely sharp. Use
care when handling this instrument. Cover the pins with the protective cap
when the instrument is not in use.

Battery Replacement
If the instrument does not switch on, displays the low battery symbol, or if the Battery Check yields
less than 44% on the wood moisture scale, replace the batteries as follows:
1. Remove the Phillips head screw from the belt clip/battery compartment located on the
rear of the instrument.
2. Remove the batteries taking note of their orientation and polarity.
3. Install three (3) new CR-2032 button batteries observing polarity.
4. Secure the battery compartment with the Phillips head screw.
You, as the end user, are legally bound (EU Battery ordinance) to return all used
batteries, disposal in the household garbage is prohibited! You can hand over your
used batteries / accumulators at collection points in your community or wherever batteries
/ accumulators are sold!

1. Remove the protective cap
2. Unscrew the electrode pins
3. Install the new pins
4. Replace the protective cap
Maintenance
Always keep the instrument dry
Prevent dirt from accumulating at the electrode pins
