1. When the high and low temperature test equipment suddenly fails during the test operation, the corresponding fault display prompt appears on the control instrument 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 troubleshoot .
Second, high and low temperature test equipment . In the high temperature test, if the temperature change does not reach the test temperature value, you can check the electrical system and eliminate the fault one by one. If the temperature rises very slowly, it is necessary to check the wind circulation system to see if the regulating baffle of the wind cycle is turned on normally. Otherwise, check the motor of the wind cycle.
Third, the high and low temperature box in the damp heat test, the actual humidity will reach 100% or the actual humidity and the target humidity are very different, the value is much lower, the former phenomenon: may be caused by the gauze drying on the humidity sensor, then Check if there is water shortage in the water tank of the humidity sensor. 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. 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.
