A common problem in the use of halogen fast moisture analyzer. Problem 1: After the moisture analyzer is turned on, the display remains black.
Answer: Possible causes are: no voltage; no power cord connected; fuse blown; instrument damaged.
Question 2: The moisture meter measures too long.
A: The closed mode that may be selected is not appropriate. Try replacing a suitable shutdown mode.
Problem 3: The moisture analyzer cannot be heated after starting the test.
Answer: The overheating of the drying unit may cause the thermal overload protection function to start. For safe operation, the moisture analyzer is equipped with double overheating protection: The drying unit has a thermal overload protection (bi-metal sensor) and can switch off the heating unit. In this case, contact your supplier.
Problem 4: The repeatability of the moisture analyzer measurement is poor.
A: Possible reasons are:
1. The sample is not uniform. For example, they have different ingredients. The more uneven the sample, the more samples are needed to obtain better reproducible results.
2. The selected drying time is too short. Extend the drying time or choose the appropriate off mode "weight loss per unit time".
3. The sample is not completely dry (eg due to surface crusts). Try mixing quartz sand for drying.
4. The selected temperature is too high or the sample is oxidized. Reduce the drying temperature.
5. The sample boils and continuously splashes to change the temperature. Please clean the protective glass.
6. When the protective glass is eroded, the heating amount cannot be fully exerted. Please clean the protective glass.
7. The temperature sensor is contaminated or damaged. Please clean the temperature sensor.
8. The console is not stable. Please use a stable console.
