(figure9).
1. Open the drawer of the device by lifting and pulling the
handle towards you (figure10).
2. Take out the measuring chamber.
3. Completely fill the measuring chamber with the material
being measured. Use the included plastic bucket and fill
the measuring chamber from the side with the metal plate
(figure11).
4. Wipe off the material at the upper edge of the measuring
chamber evenly.

shining in blue.
»The display now shows the measured values
(figure15).
»The displayed value flashes when the moisture
content exceeds the measuring range of the selec-
ted product type. A flashing value signals lowered accuracy of the measurement.
The measuring range limit of the wood chip calibration curves is 60 % moisture
content.
6. Once the reading has been taken, it can be saved on the device (see "5.3 Saving
individual readings" or "5.4 Saving several readings (a measurement series) at the
same time").

iInformation - Measuring accuracy
To increase the measuring accuracy, take three measurements of the same
material. When saving the individual readings, the device will automatically cal-
culate the readings’ average (see "5.4 Saving several readings (a measurement
series) at the same time").
iInformation - Incorrect readings
Always make sure to select the correct product type for the material you are
measuring. This prevents taking incorrect readings (see "11. Faults").
