Declaration: The main group of wood is the wood sort, which is shown on the
measurement display of your humimeter BL2. Do you want to measure wood, which
is not in the list of the main group, you should search it at the sub groups in the table
above. Then use the wood of the main group for the measuring. For example: If you
want to measure “Cherry Tree”, you have to choose the “Alder” wood at you device.
Valid measuring Range
If the measure value is grey, the standard valid measuring
range is exceeded (limits see Table). In this case the
accuracy will be decreasing.
A blinking measuring value shows you
the upper end of the measuring range. Beech 32%

28.0 MOST COMMON REASONS FOR MISS READINGS WITH BL2 WOOD
CHIPS PROBE
• Product temperature out of application range
Material below 0°C resp. above +40°C (32 to 104 °F) may cause faulty
measurements.
• Temperature difference between meter and sample
Please ensure that the device and the material under test are being stored at the
same temperature (+/-3°C) before measuring. A 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.
• Wet or mouldy material
• Frozen wood chips
If you measure such products, the accuracy will decrease.
• Water film at the measuring head
After measuring wet material a water film can arise on the sensor head. This
could lead to a too high result in the following measurement. After measuring
wet material clean both black plastic parts accurately with a dry cloth.
It is not allowed to load the measuring head
incorrect (stress, bending), other wise it can be broken.
Plug and remove the insertion probe of your BL2 wood
chips probe straight into the wood chips.
Do not move the BL2 probe crosswise to the insertion
direction after plugging in.
Do not drop the measuring head or use it for any ulterior
purposes.
A broken measuring head is no case of warranty!
