Small details to pay attention to when maintaining constant temperature and humidity machines

The small details to pay attention to when maintaining the constant temperature and humidity machine
The constant temperature and humidity machine is a high-precision, large-volume instrument. It is inconvenient for us to move it and the circuit system is complicated. Determine the cause of the error and take appropriate solutions:yU1Textile Testing Instruments, Testing Equipment Manufacturer

1. Turn off the main power of the constant temperature and humidity machine, open the drain valve under the heating barrel to position it in parallel with the pipeline, and turn off all the water inside off, clean den Dirt inside, then pull out the silicone tube, wash in water after maintenance, follow the removal method, and reinsert in the opposite direction. At a point perpendicular to the piping, turn on the main power supply behind the machine. yU1Textile Testing Instruments, Testing Equipment Manufacturer

2. The constant temperature and humidity machine temperature and humidity controller indicates that the temperature is abnormal. At this point, we need to first check the super-humidity protection in the control room to see if it's still at 150°C. yU1Textile Testing Instruments, Testing Equipment Manufacturer

3. Secondly, check that the pipework in the lab has not been cleaned for too longurde, resulting in blocked water flow, then check whether there is water in the upper water tank, if there is no water, then check whether there is water in the lower water tank. yU1Textile Testing Instruments, Testing Equipment Manufacturer

4 Finally, check whether the moisture solid-state relay is short-circuited when the heater is no problem, at this time we can use the AC voltage file of the ammeter to detect.yU1Textile Testing Instruments, Testing Equipment Manufacturer
