6. Inserting/replacing the batteries
Observe correct polarity while inserting the batteries. Remove the batteries
if the device is not used for a long period of time to avoid damage through
leaking. Leaking or damaged batteries might cause acid burns when
contact with skin, therefore use suitable protective gloves to handle
corrupted batteries.
Keep batteries out of reach of children. Do not leave the battery lying
around, as there is risk, which children or pets could swallow it.
Replace all the batteries at the same time. Mixing old and new batteries in
the device can lead to battery leakage and device damage.
Make sure that batteries are not dismantled, short-circuited or thrown
into fire. Never recharge non-rechargeable batteries. There is a risk of
explosion!
To open the battery case, loosen the screws on the back of the device.
Insert two new 1.5 V batteries (AAA) with correct polarity. (“+” = positive, “-” = negative)
Close the battery case cover.
Replace the batteries with new ones when the battery condition symbol is shown in the
display.
7. Operation
A) Measuring wood moisture
Switch the device on using the - button.
Select the calibration scale according to the kind of wood to be measured (see appendix I).
Press the button until the appropriate letter is shown in the display.
Remove the protective cap from the device.
Push the plug gauges of the measuring device into the surface of the measurement piece.
Read off the moisture content in the display directly in %H2O of the dry weight.
Alternatively (especially with hardwoodsf), the separate moisture probe (S) can also be used
for measuring. Connect it to the measuring device via the “Feuchte/Moisture” socket.
Proceed with measuring as described from Point 3 on.
Switch the device off by holding the - button down for at least 3 seconds and then
releasing it.
B) Temperature correction / calibration
The temperature of a piece of wood to be measured determines its resistance.
The device is calibrated for moisture measurement at 20°C. Moisture measurements of
warmer wood yield higher values; with colder wood, they turn out lower. There is an indirect
proportionality of the relationship of temperature to moisture content. A correction factor of 0.5
% per 5°C (arithmetically) must be observed in the process.
Example:
Read-off value: 10.5 %
