6. Compress the material in the measuring chamber now by turning the hand
wheel (1 turn per second) until the LED turns green. Now slowly (0.5 turns per
second) must be rotated until the LED flashes orange once.
7. Then immediately press the start button on the
device
8. After a few seconds, the display shows stable
water content.
9. The water content of the sample is now visible on
the display.
10. If the measure value is blinking, the valid
measuring range is exceeded (limits see list on
page 5). In this case the accuracy will be
decreasing.
11. To save the results in the save menu press the
( button). The storage
was successful when the number in front of the

12. To name the saved results press the button.
13. Empty the humimeter BLH and ensure that no
material rests are accumulated in the measuring
chamber.

13.0 MOST COMMON REASONS FOR MISS READINGS
• Product temperature out of application range
Material below 0°C resp. above +40°C (32 to 104 °F) may cause faulty
measurements. The storage of cold material in a warm storage area usually
creates condensed water which may lead to major measuring errors.
• Not adjusted material under test
Please ensure that the device and the material under test are being stored at the
same temperature (+/-3°C) before measuring. A very high temperature
difference has a negative effect on the stability of the measurement results.
• Wrong calibration curve
Before you measure your sample, double check the correct selection of the
calibration curve.
• Wrong filling quantity
Fill in exactly the right weight of wood chips in the measuring chamber.
• Wet or moldy material
• Frozen measuring material
• The steel plate which is mounted on the spindle part has to be cleaned at
regular intervals. As well as the pressure pin on the base plate (use a dry cloth
or something like that). Specifically, after measurement of wet material can be
located on the disk. This material can interfere with the following measurements!
• Compression function has to be done smoothly
To compress the hand wheel approximately one turn per second should be
rotated. When the green LED is on, the hand wheel has to be turned a half turn
further per second until the LED is orange is on.
