In addition, it should be checked that the various electronic components of the operating or execution system, as well as the connecting cables, are not loose or scratched; After long-term storage, safety checks should be carried out before use.
The maintenance secrets of low temperature and constant temperature test chamber:
1. When you use the machineturn off during low temperature operation When the process is complete, make sure the drying temperature is set to 60°C. Treat it for about half an hour;
In order not to affect the measurement time or the freezing phenomenon of the next working condition.
2. When a heated sample is placed in the box, please use an external power supply to control the power supply of the sample, and do not use the local power supply directly.
3. The cooler (condenser) of the freezer should be regularly maintained and kept clean.
