1. Q: Why does the instrument display remain blank after it is turned on?
Answer: Possible causes are: no voltage; no power cord connected; fuse blown; instrument damaged.
2. Q: Why is the measurement time too long?
A: The closed mode that may be selected is not appropriate. Try replacing a suitable shutdown mode.
3. Q: Why can't the instrument heat up after starting the test?
Answer: The overheating of the drying unit may cause the thermal overload protection function to start. For safe operation, the instrument is equipped with double overheating protection: The drying unit has a thermal overload protection (bimetal sensor) and can switch off the heating unit. In this case, contact your supplier.
4. Q: Why is the repeatability of measurement poor?
A: Possible reasons are:
1) The external environment is unstable (vibration, etc.).
2) The console is not stable. Please use a stable console.
3) The temperature sensor is contaminated or damaged. Please clean the temperature sensor.
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 sample is not completely dry (eg due to surface crusts). Try mixing quartz sand for drying. Valve inlet pump 8) The selected drying time is too short. Extend the drying time or choose the appropriate off mode "weight loss per unit time".
