WOOD/BUILDING MATERIAL
MOISTURE METER (MT1902)
PLEASE READ ALL OF THE INSTRUCTIONS BEFORE
USING THE MOISTURE METER.
This instrument can be used to measure the amount of water in the wood,
building material, and measure the environment temperature.
FEATURES:
Display: LCD display.
Measurement range:
Wood: 6 to 60%
Building material: 1.5 to 33%
Temperature: 0 to 50°C ( 32 to 122°F )
Resolution:
Wood and Building material: 0.1%
Temperature: 0 .1°C ( 0.1°F)
Accuracy:
Wood and Building material: ± 2%
Temperature: ± 2°C ( ± 4°F )
8 calibration scales(A, B, C, D, E, F, G, H), based on different types of wood
materials.
Hold function to freeze the measurement.
Low battery indication(< 2.2V).
Automatic Power-Off in 3 minutes without operation.
Power: 2xLR03 AAA 1.5V batteries.
Operating Environment:
Temperature: 0 - 40°C
Relative Humidity < 85%
INSTALLING BATTERY:
1. Remove the battery compartment cover.
2. Insert the batteries with the correct polarity.
3. Reattach the battery compartment cover.

OPERATION INSTRUCTION:
1.Press the " " button to turn on the instrument, press and hold the "
button for about 3 seconds to turn off the instrument.
2.Selecting desired Measurement Mode:
a. After turn on the instrument, press the " " button to select desired
measurement mode.
The two measurement modes are as follows:
Wood moisture measurement mode ("WOOD" displays), building material
moisture measurement mode ("BLDG" displays).
Wood moisture measurement mode has 8 calibration scales(A, B, C, D, E, F,
G, H), based on different types of wood materials.
Check the Calibration Tables first, and then press the "
to the matched calibration scale.
b. After the desired measurement mode is selected, you can start
measurement.
c.Temperature measurement mode displays in Celsius temperature
measurement mode ( "°C" displays) or Fahrenheit temperature
measurement mode ( "°F" displays).
Press " " button to switch between °C and °F.
3.Performing Measurement
a. For temperature measurement, the display shows the present environment
temperature directly.
b. Before taking the first measurement check that the instrument is
functioning correctly.
For this you will need to use the Test Aid.
On the Test Aid there are two measurement holes as picture.
1. Protective cap
2. Pins
3. Moisture value of
building material
4. Moisture value of wood
5. Temperature value
6. Moisture value
7. Low battery indication
8. HOLD icon
Switch to Wood moisture measurement mode ("WOOD" displays) and
9. WOOD icon
choose A scale.
10. BLDG icon
Insert the measuring pins into the measurement holes, the measuring
11. 8 calibration scales(A-H)
value on the display will show between 16.6% to 20.6%.
12. Hold button
The instrument is workable when measured value was in the error range.
13. °C/°F conversion button
c.To perform moisture measurement, press both pins into the wood or
14. Right arrow button
material to be measured, read the value on the display.
(A-H option button)
d. Measured value will appear on the LCD, there will a Beep sound when
15. Mode & ON/OFF button
the measured value greater than a certain value.
16. Battery case (Back of Unit)
Wood: ≥16%.
Building material: ≥20%.
4. Freeze the measurement
Press the "
on the screen. By pressing the "
"
measuring mode will get reactivated.
5. Automatic Power-Off feature
If you don't operate the instrument (or the reading does not change) about
3 minutes, the instrument will be turned off automatically.
6.When the symbol "
should be replaced.
MAINTENANCE:
The moisture meter has been designed to be a low maintenance instrument.
However, in order to maintain its performance, you must always follow these
" button to switch
simple directions:
• AVOID exposing the instrument to shock, continuous vibration, or extreme
hot or cold temperatures.
• ALWAYS attach the protective cap when not in use.
• ALWAYS keep the instrument free of dust and liquids.
• Check the battery regularly to avoid deterioration.
• ALWAYS remove the battery when storing the instrument.
• DO NOT attempt to change any part of the unit.
• DO NOT disassemble the instrument. This will void the warranty.
• Store the instrument in a dry location.
• After measurement, clean the probes and the case using a clean cloth.
