How to repair the failure of low temperature constant temperature bath

As one of the commonly used environmental testing machines, the low temperature constant temperature bath breaks down in the process of using and dealing with it is a problem we often encounter There are many answers to this kind of questions now, but there are not many people who know the specific operation steps about what tests we should do to verify whether the test box is well repaired after the bath failure is repaired The following is a brief introduction to the performance test required after bath failure After bath maintenance, we need to test its main refrigeration performance and safety performance First of all, we need to pay attention to the test environment of the low temperature constant temperature bath must be within the range of the test chamber, and the specific temperature, humidity and air flow speed have corresponding requirements After everything is ready, we can prepare for the test We need to use a measuring meter about 500 volts as the insulation resistance of the bath When using, the length of the measuring meter shall not be less than two meters If a separate measuring compressor is used, its length must be greater than five meters In order to ensure that the bath can be used normally after maintenance, we can repeatedly test the switch of the low-temperature thermostatic bath for three times, and each time the bath is shut down and running, the time must be about three minutes What's more, we need to pay attention to that the starting performance of the bath in the test is based on the voltage of 380V or so, so as to avoid secondary damage during the test
