Why should the high and low temperature test chamber be debugged and calibrated? In order for the high and low temperature test chamber to exert its maximum efficiency and stability in the hands of customers, the most important thing is to debug and calibrate the factory during the 15-day forward behavior period. The following are the three methods for calibrating the high and low temperature test chamber and their The advantages and disadvantages of: 1. The advantage of calibrating this method under no-load conditions is that the entire working area of ​​the high and low temperature test chamber has been calibrated, and the applicability of the high and low temperature test chamber can be effectively evaluated. The main disadvantage is that it cannot evaluate the impact of the test sample on the test chamber. 2. Calibration under load conditions: The advantage of this method is that it can more accurately evaluate the impact of the test sample on the performance of the test box, and it is easy to obtain the detailed information of the environmental test of the key components or parts of the test sample. The main disadvantage is that when the test sample is changed, it needs to be recalibrated. 3. Real-time measurement during use: This method not only has the advantages of the above method. Moreover, the comprehensive environmental parameters of the test sample in the environmental process can be obtained, which is often used in product tests with high environmental requirements. Its main disadvantages are: measurement equipment is required for each environmental test, and the calibration method under no-load conditions is usually used in the calibration of the test chamber. Through the above method to debug and calibrate the high and low temperature test chamber, we can try to simulate a more reliable test environment, so as to make accurate analysis and evaluation of the sample.
