Precautions when serving the thermostat box

The constant temperature and humidity box belongs to the high precision instrument, and the volume is larger, in the move is more inconvenience, the circuit system is complex, when it fails, we often do not know where to start, and they can timely judge the cause of the fault and make corresponding solutions, pay attention to the following aspects: 1, the thermostatic humidity box temperature and humidity controller shows abnormal temperature, then first of all to check the control room ultra-humidity protector.
to check whether the lines in the laboratory have not been cleaned for too long, resulting in poor water flow, and then check whether there is water in the upper water tank, if there is no water, and then check whether there is water in the water tank.
2, the total power supply of the thermostat thermostat is turned off, the drain valve under the heating bucket is opened to a position parallel to the line, the water inside is discharged, the dirt inside is cleaned, and then the silicone pipe is removed, washed in water, 3, after maintenance is completed in accordance with the way of removal, the reverse direction is installed back, after the installation is completed, the drain valve under the humidification bucket, closed to the position perpendicular to the pipe, and then the power supply is always opened.
check the humidity of the solid state relay after 4 is shorted, if the heater is not a problem, then we can use the meter AC voltage file to detect.
