In the high temperature test, if the temperature change does not reach the test temperature value, the electrical system can be inspected and the faults can be eliminated one by one. If the temperature rises very slowly, it is necessary to check the air circulation system to see if the regulating baffle of the wind cycle is normal. On the contrary, check whether the motor of the wind cycle is running normally. If the temperature is too high, you need to set the PID setting parameters. If the temperature rises directly and the temperature is over-protected, then the controller fails and the control instrument must be replaced. If the low temperature does not reach the test index, then you should observe the temperature change, whether the temperature drop is very slow, or the temperature has a rising trend after the temperature reaches a certain value. The former should check whether the studio will be used before the low temperature test. Dry, leave the studio dry and then put the test sample into the work room and then test it. If the test sample in the studio is too much, the wind in the workroom cannot be fully circulated. After eliminating the above reasons, it is necessary to consider Is it a malfunction in the refrigeration system? Another possibility is that the wet gauze is hardened due to the long use time or the purity of the water supply, so that the gauze becomes hard and the gauze can not absorb moisture and is dry. The above phenomenon can be eliminated by replacing or cleaning the gauze. The latter phenomenon is mainly because the humidification system does not work. Check the water supply system of the humidification system, whether there is a certain amount of water in the water supply system, whether the water level control of the humidification boiler water level is normal, and whether the water level in the humidification boiler is normal. If everything above is normal, then check the electrical control system, which should be repaired by professional maintenance personnel. In the damp heat test, the actual humidity will reach 100% or the actual humidity will be very different from the target humidity. The value is much lower. The former phenomenon may be caused by the drying of the gauze on the wet bulb sensor. Then check the wet bulb sensor. Whether there is water shortage in the water tank, the water level in the water tank is automatically controlled by a water level controller. Check whether the water supply system of the water level controller is normal and the water level controller works normally. When the equipment suddenly fails during the test operation, the corresponding fault display prompt appears on the control meter and there is an audible alarm prompt. The operator can quickly check which type of fault is involved in the troubleshooting chapter of the operation of the equipment, and then ask the professional to quickly eliminate the fault to ensure the normal operation of the test. Other environmental testing equipment will have other phenomena in use, and it will be specific phenomena, specific analysis and elimination.
