High and low temperature of the high and low temperature approach to troubleshooting troubleshooting methods

High and low temperature in the high-temperature test, such as temperature change to reach the test temperature, you can check the electrical system, troubleshooting one by one. Such as temperature rose slowly, it is necessary to check the air circulation system, look at the damper is open normal air circulation, and vice versa, check the air circulation motor is functioning properly. If the temperature overshoot powerful then you need to set the parameters of the PID tuning. If the temperature rise directly, over temperature protection, then, the controller failed, control instruments to be replaced.
Second, the high and low temperature in the sudden failure of the test is running, the control on the instrument corresponding fault display prompts and voice alarm. The operator can control the operational use of the device in the Troubleshooting chapter quickly check which category failure, you can ask professionals to quickly troubleshoot to ensure the normal conduct of the trial. Other environmental testing equipment in use there will be other phenomena, it should be a specific phenomenon, specific analysis and troubleshooting. Environmental testing equipment but also regular maintenance, refrigeration system condenser cleaned regularly, lubrication, electrical control system maintenance checks on a regular basis for moving parts shall be specified, such work is essential
Third, the high and low temperature low temperature reach test indicators, then you have to observe the changes of the temperature, the temperature drop is slow, or the temperature to a certain value tends to increase in temperature, the former is necessary to check, and low temperature Before the test, whether the studio drying, the studio will remain dry and then test sample into the working chamber to do the test, the working chamber of the test sample is placed too much, so that indoor air can not be the full cycle of exclusion of the above reason, we must consider whether it is a fault in the cooling system, so that would be for the manufacturers of maintenance professionals. The latter phenomenon is the use environment of the device is bad due to the ambient temperature, the device is placed to meet the requirements placed distance from the wall (Case) (in the device operation instructions for use are specified).
Fourth, the high and low temperature in the hot and humid test, the actual humidity will reach 100% or the actual humidity and target humidity vary widely lot of low value, the former phenomenon: It may be caused by dry gauze on the wet bulb sensor, it is necessary to check whether the lack of water in the water tank of the wet bulb sensor, the water level in the tank is automatically controlled by a level controller, check the water level controller water supply system is normal water supply, water level controller is working properly. Another possibility is that the wet bulb gauze from the use of a long time, or the quality of water purity reasons, make the gauze hardens, the gauze can not absorb moisture and dry, replace or clean gauze to exclude the above phenomenon. The latter phenomenon is mainly humidification system does not work, the water supply system of the humidification system, water supply system whether there is a certain amount of water, the control of boiler water level of the humidifying water level control is normal, whether the normal water level within the humidification boiler. Such as the above, all normal, it would have to check the electrical control system, professional service personnel.
