Most common reasons for miss readings
• Product temperature out of application range
Material below 0°C resp. above 40°C may cause faulty measurements. The storage of cold material
in a warm storage area usually creates condensed water, which leads to major measuring errors.
• Not adjusted material under test
Let your device adjust to the surrounding temperature of the material for approx. half an hour. A
very high temperature difference has a negative effect on the stability of the measurement results.
• Wrong calibration curve
Before measuring your sample, please double-check the correct selection of the calibration curve.
• Wrong filling quantity
Fill in exactly the right weight (+/- 0,2 gram) of material into the measuring chamber.
• Wet or mouldy material
• Stored and fermented corn silage from whole grains may lead to higher value
• Frozen measuring material
If the material is frozen, the accuracy decreases significantly.
Device maintenance instructions
To provide a long life of your device please do not expose it to strong mechanical loads or heat e.g.
dropping it or direct sunlight exposure. Clean your device using a dry cloth. The measuring chamber
needs to be cleaned with a dry and soft brush. Any kind of wet cleaning damages the device. The
instrument is not rainproof. Keep it in dry areas. When the device is not used for a longer period (6
months) or when the batteries are empty, remove the batteries to prevent a leakage of the battery
acid.
