1. Calibration under no load conditions: The advantage of this method is that the entire working area of the test chamber is calibrated, the test sample becomes more re-calibrated, and the applicability of the high and low temperature test chamber is effective. evaluation of. Its 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 accurately evaluate the influence of the test sample on the performance of the test chamber, and it is easy to obtain detailed information on the environmental test of key parts or parts of the test sample. The main disadvantage is that it requires recalibration when changing test samples.
Third, real-time measurement during use: This method not only has the advantages of the method described in 1 and 2, but also can obtain the environmental parameters of the test sample during the environmental test, often in the test of products with high environmental requirements. use.
