Determine Correction Factor And Enter - KERN MLS 50-3IR160 Instruction Manual

9.7 Determine correction factor and enter

Certain materials emanate more heat than is contributed from outside.
In order to obtain a faultless measuring result a correction is necessary in such a
case.
This setting allows the user to correct differences between the set temperature of the
moisture analyzer and the actually measured temperature on the test item.
Determination of the correction factor:
The balance is in normal weighing mode. Put a test quantity onto the sample plate.
Place the sample plate onto the dish receptacle.
Plug a thermic sensor through the opening at the left side of the heating attachment.
Close the heating attachment. Now try to get the sensor as close as possible to the
test material on the sample plate.
Start now the drying process and compare the regulated temperature on the MLS50-
3 and the read temperature on the temperature sensor.
Please calculate the correction factor according to the following formula:
Formula:
Correction =
Example: The measured temperature is 121°C, the temperatur set is
110°C, the correction is 0,11.
Typical materials with high temperature irradiation:
Material
Flour
Coal dust
Humid tea leaves
Dry tea leaves
Cement
Determination of the correction factor:
