1. Problem: If the temperature change does not reach the test temperature value in the high temperature test
Solution: In this case, you can first check the electrical system and troubleshoot them one by one. If the temperature rises in the constant temperature and humidity chamber is too slow, it is necessary to check the air circulation system, and whether the regulating flap of the air circulation is normal. On the contrary, it is necessary to check whether the wind cycle motor is operating normally. If the temperature is too high, you need to set the PID setting parameters. When the temperature rises directly over temperature protection, if the controller fails, it needs to replace the control instrument or solid relay.
2, the problem: when the constant temperature and humidity test chamber low temperature can not reach the test index
Solution: At this time, it is necessary to observe that the temperature change is very slow, or the temperature has a tendency to rise after the temperature reaches a certain value. If the former is to be checked, whether the studio is dried before the low temperature test is performed. So that the studio is kept dry, and then the sample is put into the working room for testing. If the sample in the working room is placed too much, the wind in the working chamber cannot be fully circulated. After eliminating the above reasons, it is necessary to consider whether the refrigeration system is faulty. In this case, you need to ask the professional of the manufacturer for repair.
3. Problem: The constant temperature and humidity test chamber equipment suddenly fails during the work, and the corresponding fault prompt appears on the control instrument and there is an audio alarm.
Solution: The user can use the device according to the operation of the device. In the troubleshooting chapter, quickly check which type of fault belongs. Therefore, professional maintenance personnel should perform troubleshooting to ensure that the test is carried out normally. Other environmental testing equipment will have other conditions in use, and it needs to be solved according to the status quo.
