Teach you how to identify the problem of high and low temperature test equipment

　　Original Source: teach you how to determine the failure of the original high and low temperature test equipment: forest-frequency instrument
　　if we had to master or read the medicine people, should understand the way medicine medical consultation is: look, smell, and asked, cutting four aspects. Looking view, listen to sound, ask disorder, where the body touch the pulse for this purpose clear out the problem. The following Xiaobian teach you how clear whether the high and low temperature test equipment out of the problem.

　　First, check: viewing environment through the work chamber of each member in the situation, the key concept check its refrigeration unit, circuitry, Huxixitong three part, to distinguish whether they are all normal work.
　　Second, in listening: listening environment plug-in enable sound operation of the compressor refrigeration chamber if everything is normal, there is no abnormal sound, there is no running centrifugal fan noises, the noise is not too big.
　　Third, the experience: lay a hand high and low temperature test equipment related to its position experience hot and cold, tremor and other conditions conducive to resolving common fault characteristics and location.
　　Fourth, detection: in order to accurately distinguish between common fault characteristics and location, often starting equipment, inspection instrument panel and accurate measurement of technical parameters of a high temperature chamber.
　　V. Analysis: After the results of the inspection of several types of way obtained, then many cases only reflect part of the environmental test chamber. Thus, for some elements to carry out a more comprehensive analysis, all levels accurately determine the characteristics and location of common faults.
　　High and low temperature test equipment spare parts are inter-related and therefore, will be a common component failure can cause a lot of high and low temperature test equipment "disease complications." Identify common failures of high and low temperature test equipment that is around six, we can examine the details of their environmental chambers based on small series.
