Causes of alarm in constant temperature and humidity test chamber

The constant temperature and humidity test chamber will sometimes cause an alarm during the whole process of the experiment. Under what conditions can the equipment cause an alarm? How should we deal with such difficulties? There are many factors that cause equipment to cause alarm, but the key factors are as follows:

Overheat alarm: The test object is generally equipped with a controller and an overheat protector. Therefore, when the equipment is conducting experiments, when the specific temperature of the detected area exceeds the preset temperature, the equipment will stop operation and the alarm device will automatically alarm. At this time, we need to set the temperature again to enable the equipment to work normally.

Overpressure alarm of refrigeration compressor: the working pressure of refrigerant of refrigeration compressor is set at the beginning, but sometimes the equipment may exceed the preset value due to too much or too little refrigerant. To quickly deal with this problem, manual calibration should be carried out, and then the system software can only be repaired.

Alarm of switch power constant temperature and humidity test box: when the switch power cord of the equipment is out of phase; Or if the number of lines is too many and the order is out of order, the equipment will automatically terminate and cause an alarm. At this time, what we must do is to quickly find out common faults and deal with them. Restore the constant temperature and humidity test chamber.
