2022-02-22How to solve the constant temperature and humidity chamber temperature and humidity controller? The constant temperature and humidity box belongs to high precision instrument, and the size is large, and there is more inconvenient in moving. At the same time, its circuit system is complex. When it is faulty, the user often doesn't know where it is. The Shanghai Sheng Instrument Technical Experts mainly introduces the constant temperature and humidity changing temperature and humidity controller display temperature, how to determine the cause of the failure and make corresponding solutions. 1. The temperature and humidity controller of the constant temperature and humidity is abnormal. At this time, we must first check the overwescent protector of the control unit to see whether it is still 150 ° C. 2. Second, after checking the pipeline in the laboratory, it has not been cleaned for too long. 3, ZUI After checking the solid state relay of humidity, there is no short circuit. If there is no problem with the heater, then we can use the electricity to AC voltage file to detect.
