26.0 MOST COMMON REASONS FOR MISS READINGS WITH BL2 HAMMER
• Product temperature out of application range
Material below 0°C resp. above +50°C (32 to 122 °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.
• Frozen wood or beetle infested wood
If you measure such products, the accuracy will decrease.
• Measurement through bark
In fact of that the accuracy will decrease.
• Direct solar radiation

MOST COMMON REASONS FOR MISS READINGS WITH FLW TESTER
• 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.
• 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.

MEASURING PROCEDURE FLW TESTER
1. For a correct measurement please ensure that the
device has the same temperature than the material (+/-
3°C). For that reason, let your FLW tester adjust to the
surrounding temperature of the material before
measuring.
2. Switch on the device: Press the key for three
seconds.
