31.4. Troubleshooting
Problem: no reaction to pressing main switch on/off key (no display reaction).
Probable cause:
• No voltage in mains
• Damaged power cord
• Damaged fuse of the moisture analyzer
• Moisture analyzer defect
Problem: too long pending time for drying process finish.
Probable cause:
• Selected finish mode of drying process is incorrect. Carry out experimental
tests to select a proper means of finish mode.
Problem: measurements are not repeatable
Probable cause:
• non-uniform sample content. Prepare the sample from larger amount of
substance.
• drying time is too short. Change finish mode criteria of the testing process.
• drying temperature is too high, causing sample’s oxidizing. Lower drying
temperature.
• tested sample boils. Lower the drying temperature.
• the temperature sensor is contaminated or defected. Clean the
temperature sensor.
• the workbench on which the moisture analyzer is located is unstable.
Change the location of instrument’s operation.
• - the ambient area is incompatible with the requirements (vibrations,
drafts, etc.). Change the ambient conditions for compatible ones according
to the guidelines of this user manual.
