What are the operating procedures of the high and low temperature test chamber?

1. High-temperature test 2. Turn on the main power switch 3. Place the samples in the test chamber, and the products should not come into contact with each other; close the door of the test chamber. 4. Turn on the temperature controller and set the temperature according to the specified requirements. The operation method is as follows: (Press the "Setting" button to set the temperature and slope that need to be tested. If humidity is required, the same operation.) 5. Press the run button 6. After the high-temperature test, press the start button again, and the high and low temperature chamber will stop working. After the natural temperature cools down by 0.5h to 1h, take out the sample. 7. The extracted sample is placed in the air. After natural cooling for 1h to 2h, observe the surface changes of the sample and record it in the [High and Low Temperature Test Report]. 8. During the experiment,If you need to observe the condition of the sample, just turn on the light switch of the test chamber, but do not press it for a long time. 9. Low-temperature test (after the high-temperature test, it needs to cool down naturally by 0.5h to 1h, and then do the refrigeration test). 10. Turn on the main power switch. 11. Place the samples in the test chamber, and the products should not come into contact with each other; close the door of the test chamber. 12. Turn on the temperature controller according to the temperature control switch, and set the temperature according to the prescribed requirements according to the above operating method of the temperature controller. 13. Press the start button, and the low-temperature test begins. 14. After completing the low-temperature operation, press the stop button and take out the sample after the temperature cools down naturally by 0.5h to 1h. 15. After placing the removed sample in the air for 1h to 2h, observe the changes on the surface of the sample.
