Maintenance methods for walk-in high and low temperature test chamber

Maintenance method one of walk-in high and low temperature test chamber: comparison method

The specific method is: let the faulty instrument and the normal instrument run under the same conditions, and then the CLM high and low temperature alternating damp heat test box will detect the signal at some points, and then compare the two sets of signals measured. If there is a difference, the fault can be determined. Here it is. This method requires maintenance personnel to have a lot of knowledge and skills.

Two instruments of the same model are required, one of which can operate normally. The high and low temperature test boxes produced by this method must have the necessary equipment, such as multimeters, oscilloscopes, etc. According to the nature of comparison, there are voltage comparison, waveform comparison, static impedance comparison, output result comparison, current comparison, etc.
