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
