Original source: How should the high and low temperature test chamber be properly turned on? Edit: Lin frequency instrument High and low temperature test chambers are frequently used in today's high-tech products, and the environmental conditions they experience are more and more complex. We only have to properly define the environmental conditions of the products and correctly select the products. Environmental protection measures are an essential part of ensuring their high quality; artificially simulated natural environment tests are scientific summaries of actual environmental impacts, characterized by typicalization, standardization, ease of use, and ease of comparison; diversification of environmental conditions and environment The importance of the test also places stricter requirements on environmental test equipment. High and low temperature test chambers should try to avoid the following situations when conducting tests: 1. When the equipment is being tested, the box door must not be opened unless necessary. The high temperature is out of the box, which is very dangerous; the outside of the box door is still high temperature, which is easy to cause burns; high temperature air may trigger fire alarm and cause errors. action; 2. Avoid continuously opening and closing the refrigeration unit within 3 minutes; 3. If a hot test piece is placed in the high and low temperature test box, please use the external power supply for the power supply control of the test piece. Do not use the power supply directly. 4. Testing explosive, flammable and highly corrosive substances is absolutely prohibited by this equipment; 5. Please read the machine manual before operating the machine. 6. Please note that the device is indeed safely grounded; 7, circuit breaker, over-temperature protector, is to provide the test products of this machine and the operator's safety protection, so please check regularly; The above is a series of problems that need to be paid attention to when the high and low temperature test chambers are tested. We should try to avoid these problems, so as to ensure the personal safety of the operators and reduce the maintenance of the equipment.
