Handles and Hot parts
The following points become hot during and soon after measurements.
Other precautions
• When the drying temperature is set to 200°C, the thermostat may cut the power of the halogen lamp
after 30 minutes. The next measurement can be started only when the halogen lamp has cooled down.
• When a measurement time exceeds one hour, the maximum temperature is automatically regulated
down to 160°C for safety.
• During measurement, the STOP key is always effective. If there is an error or danger, press the STOP key.
• Turn the power switch off immediately should the sample catch fire.
For accurate measurement
• The working place for the analyser should be solid and free from vibration, drafts and as level as possible.
• Install the analyser where it is not affected by heaters, air conditioners or air flows.
• Keep the analyser away from equipment that generates magnetic fields.
Pre-treatment of sample
• Break grain samples into small, uniform pieces this will avoid explo-
sion and help the drying process.
• Spread the sample on sample pan as evenly as possible.
• Apply an optimal sample weight. If the sample weight is too small,
precise results may not be possible.
• To repeat measurements, keep the same sample weight.
• It is highly recommended to pre-heat the analyser before the first
sample measurement.
• Place the sample only on a sample pan kept at room temperature. When a sample is put on a hot
sample pan, results may be errertic.
• The glass fibre sheet (accessory AX-MX-32) is availble for measurement of liquid samples.

• Use the calibration sample to check the analysing process and accuracy of the analyser.
Sodium tartrate dihydrate contains a theoritical moisture 15.66% in the molecule. However, the cali-
bration sample may absorb ambient moisture and show higher, up to 0.09%, moisture content above
it`s theorical value.
• Recommended measurement for the calibration sample is followed by preheating process of 8 min-
utes at 160°C, set the condition to 160°C, MID. in standard mode. Sample volume is 5g. The result is
usually between 15.50 % and 16.00 %. Refer to "Select a Unit" of section 7.2.
• The same calibration sample can not be used again.
