The high-temperature test chamber is used to test and determine the parameters and performance of electrical, electronic and other products and materials after the temperature environment changes after high temperature or constant testing. So how to check the good and bad of the high temperature test chamber in practice?At this time, we need to use some data to form a tight control of the high temperature test chamber. Now there are no more than three inspection methods (empty machine experiment method, drawing test method, actual machine operation method), let's introduce these methods one by one!
Method 1: Empty machine experiment method This method has a premise, that is, it needs to be completed on the empty plane, the so-called "empty machine" is actually the need for us not to put in any samples, let it run after starting, through some data records and some empirical things so that we can better grasp the relevant performance of the high temperature test chamber, this method is not dangerous, but some of the data obtained is not too real, but it is also a very good way to check the high temperature test chamber. Method 2: Drawing experiment method Although this method is the least dangerous, but he is equivalent to "talking on paper", which problems will be encountered in actual operation is a simple conjecture, so this method can also be used, but it must be before the empty plane experiment method, because he got some theoretical data, so it is not in line with the current theory and practice of the mutual view, so people often omit it. Method 3: Actual machine operation method As the name suggests, this method is to use equipment, on the basis of the use of physical objects to test the relevant characteristics of the high temperature test chamber, although this method is the most simple and clear, but there are a lot of unstable factors in the middle of the process, all should be carefully checked before the use of the high temperature test chamber instructions.
