17.0 MOST COMMON REASONS FOR MISS READINGS
• Product temperature out of application range
Material below 0°C resp. above +40°C may cause faul ty measurements. The
storage of cold material in a warm storage area usually creates condensed
water which may lead to major measuring errors.
• Discrepancy in temperature between device and material
Please ensure that the device and the material under test are being stored at the
same temperature (+/- 3°C) before measuring. Protec t your measuring device
from direct sunlight for a reasonable time period before taking a measurement.
A high temperature difference has a negative effect on the stability of the
measurement results.
• Wrong calibration curve
Double check the correct selection of the calibration curve before measuring.
• Wet or mouldy material
• Frozen measuring material or material containing snow
This leads to a major decrease in accuracy.
• Direction of plugging in
The Direction of plugging has a great influence on the accuracy. Necessarily
follow the instructions according to the beginning of the manual!
• Compressed density outside the application range
If the compressed density differs from that specified, there may be deviations!
• Moving the measuring head after the plug in leads to miss readings!
• 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 measurements. After measuring
wet material clean both black plastic parts of the measuring head accurately with
a dry cloth.
ATTENTION: Risk of injury by measuring head!
Keep away from children younger than 16 years!
