When the temperature shock test chamber is in operation, please do not open the chamber door unless necessary, as it may cause the following adverse consequences

2. The temperature shock test chamber must be safely grounded to prevent static induction

3. Avoid shutting down the refrigeration unit within three minutes before turning it on

4. If the heating test sample is placed inside the box, please use an external power supply for the test sample power control, and do not directly use the local power supply; When placing high-temperature samples for low-temperature testing, attention should be paid to keeping the opening time of the box door as short as possible

5. Circuit breakers and over temperature protectors provide safety protection for local test products and operators, so please regularly check the temperature shock test chamber

6. It is prohibited to test explosive, flammable, and highly corrosive substances

7. The lighting should be turned off at all times except when necessary

Before doing low-temperature work, the studio should be dried dry and dried at 60 ℃ for 1 hour

During the experiment, the refrigeration unit cannot be turned on when the temperature in the low-temperature chamber exceeds 55 ℃

10. On any section perpendicular to the prevailing wind direction, the sum of the cross-sectional areas of the test load should not exceed one-third of the working section at that location

11. The basket guide rail and rack of the temperature shock test chamber should be regularly lubricated with oil

12. The tested sample should be fixed in the center of the sample rack as much as possible, and should not be placed on one side randomly, which may cause the basket of the temperature shock test chamber to tilt
