When the high and low temperature test box suddenly fails during the test operation, the corresponding fault display prompt appears on the control instrument and there is a voice alarm prompt. The operator can quickly check which type of fault belongs to in the troubleshooting chapter of the operation of the equipment, and then the professional can quickly eliminate the fault to ensure the normal operation of the test. Other environmental test equipment will have other phenomena in use, it must be specific phenomena, specific analysis and exclusion.
In the high temperature test, if the temperature change does not reach the test temperature value, the electrical system can be checked and the faults can be eliminated one by one. If the temperature rises very slowly, it is necessary to look at the air circulation system and see if the adjustment baffle of the air circulation is normally open. Conversely, check whether the motor operation of the air circulation is normal. If the temperature overshoots badly, then you need to set the PID setting parameters. If the temperature rises directly, over-temperature protection, then the controller fails and the control instrument must be replaced.
If the low temperature does not reach the test target, then you must observe the temperature change, whether the temperature drop is very slow, or if the temperature rises after the temperature reaches a certain value, the former must check whether it will be the studio before the low temperature test. After drying, the test chamber is kept dry, and the test sample is placed in the work chamber for further testing. The test chamber in the work chamber 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, so we must ask the factory's professionals to repair. 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 (both are specified in the equipment operating instructions).

　　 The high and low temperature test chambers should also be regularly maintained. The condensers of the refrigeration system should be regularly cleaned. The moving parts should be lubricated according to the instructions, and the electrical control system should be regularly maintained and checked. These tasks are indispensable.
