1. 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 to eliminate the fault one by one. If the temperature rises very slowly, then you should check the wind circulation system Whether the adjustment baffle is opened normally, otherwise, check whether the motor of the wind cycle is operating normally. If the temperature overshoot is severe, then the PID setting parameters need to be set. If the temperature rises directly and the overtemperature protection occurs, the controller fails and the control instrument must be replaced. 2. The low temperature of the high and low temperature box can not reach the test index, then you should observe the temperature change, whether the temperature drops slowly, or the temperature has a tendency to rise after the temperature reaches a certain value, the former should check it and do a low temperature test Whether the studio is dried before, keep the studio dry, and then put the test samples into the work room before testing, whether the test samples in the work room are placed too much, so that the wind in the work room cannot be fully circulated, and the above reasons are excluded After that, it is necessary to consider whether it is a fault in the refrigeration system. In this case, it is necessary to ask the manufacturer's professional personnel for maintenance. The latter phenomenon is caused by the poor use environment of the equipment. The ambient temperature of the equipment and the location (the distance between the back of the cabinet and the wall) must meet the requirements (as specified in the equipment operation instructions). 3. Single-point rapid temperature change test When a fault suddenly occurs during the test operation, the corresponding fault display prompt and an audible alarm prompt appear on the control instrument. The operator can refer to the troubleshooting in the operation of the equipment. Quickly check out which type of fault belongs to, you can ask a professional to quickly eliminate the fault to ensure the normal conduct of the test. There will be other phenomena in the use of other environmental test equipment, then specific phenomena, specific analysis and elimination. Environmental test equipment should also be regularly maintained, the condenser of the refrigeration system should be cleaned regularly, and moving parts should be refueled according to the instructions Lubrication, regular maintenance and inspection of electrical control systems, etc., these tasks are essential. 4. When the high and low temperature box is doing the damp heat test, the actual humidity will reach 100% or the actual humidity is very different from the target humidity, and the value is much lower. The former phenomenon: it may be caused by the drying of the gauze on the wet ball sensor, then To check whether the water tank of the wet ball sensor is short of water, 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 whether the water level controller works normally. Another possibility is the wet ball Gauze can harden the gauze due to the long time of use, or the purity of the water supply, so that the gauze can not absorb the moisture and dry, and the above phenomenon can be eliminated by replacing or cleaning the gauze. The latter phenomenon is mainly that 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 to control the water level of the humidification boiler is normal, and whether the water level in the humidification boiler is normal. If all of the above is normal, then check the control system of the electrical appliance. This requires professional maintenance personnel to overhaul.
