This problem will rarely appear, but if the operator uses improper, it will also cause its phenomenon, but sometimes there are also related to the production technology of the manufacturer.
So here's I want to share with you:
1. Thermal shock chamber temperature overshoot phenomenon refers to the first time when the startup, the studio temperature exceeds the set temperature more than 3℃, and then slowly reduce and stabilize at the set temperature phenomenon.
2. The reliability of the artificial environment provided by the equipment undoubtedly plays a vital role in the whole test result. Some test samples are very precise, and the precision may be affected if the temperature is too high. The following phenomena belong to the normal warm punching phenomenon: With the corresponding ±2℃ temperature deviation requirements or requirements of the overimpulse of the cold and hot cycle impact test box and the temperature of the test point in a certain proportion, such as O 100℃ temperature overimpulse does not exceed 2℃, 100℃ overimpulse does not exceed 2% of the test point. The control instrument of the equipment is relatively easy to adjust the control accuracy, and has the function of automatic calculation, programmable and massive storage of historical data and curves.
3. When the temperature overshoot beyond standard, need to contact the manufacturer timely correction, or third-party metrology institute for calibration, please, when excessive temperature overshoot due to the hot and cold cycle impact test box manufacturers caused by improper use of parts and manufacturing technology, so once again remind users do not blindly pursue infinite low price when buying equipment equipment.
These are all the content to share with you the requirements of the temperature overshoot of the thermal shock chamber.
