Fast temperature test chamber troubleshooting

When the rapid temperature change test box suddenly fails during the test, the control will appear in response to the corresponding fault prompts, and the operator will perform troubleshooting according to the corresponding equipment. Here, Kunshan Haida instrument technicians pointed out that several rapid evacuation tests should be performed. The box fault method is convenient for everyone's reference to ensure the normal operation of the test.

　　 Fast temperature test chamber in high temperature test:

Fault 1: The temperature change cannot reach the test temperature value. Check the electrical system and eliminate the fault one by one.

Fault 2: When the temperature rises very slowly, it is necessary to check the wind circulation system to see if the wind turbine's regulating baffle is normally open. Conversely, check whether the wind turbine's operation is normal.

Fault 3: The temperature overshoots badly. Then you need to set the PID setting parameters.

Fault 4: The temperature rises directly and over-temperature protection. Then, if the controller fails, the control instrument must be replaced.

　　 Rapid temperature change test chamber in low temperature test:

Failure: Low temperature does not reach the test target,

Remedy: Observe the temperature change, it is the temperature drop is very slow, or the temperature rises after the temperature reaches a certain value, the former must check, do low temperature test before drying the studio, so that the studio is dry Then put the test sample into the working room and do the test again. The test sample in the work room is placed too much, so that the air in the work chamber cannot be fully circulated. After eliminating the above reasons, it is necessary to consider whether it is a fault in the refrigeration system. This will require the factory's professionals to overhaul. The latter phenomenon is caused by the poor use environment of the equipment. The ambient temperature of the equipment and the location of the equipment (the distance between the cabinet and the wall) must meet the requirements (in the operating instructions of the equipment).
