Briefing on the operation of the high and low temperature damp heat test chamber.
1. Introduction to the test chamber.
High and low temperature damp heat test chamber is a kind of test equipment widely used in electronics, electrical appliances, instrumentation, automobiles, aerospace and other industries.
It is able to simulate various environmental conditions, such as high temperature, low temperature, damp heat, etc., to test the performance and reliability of products in different environments.
Second, the operation process of the test chamber.
1.Ready to boot.
Plug the chamber's power plug into a power outlet and make sure the power switch is off.
Check that the product fixtures in the test chamber are installed correctly and that the inside of the chamber is clean and tidy.
2.Set the temperature parameters.
Open the control panel of the test chamber and set the temperature parameters according to the test requirements.
Parameters that usually need to be set are: temperature range, heating rate, cooling rate, holding time, etc.
Once set, save the parameters and close the control panel.
3.Start the trial.
Press the start button of the chamber and the chamber will start heating up or cooling down according to the set temperature parameters.
During the test, the temperature change of the test chamber can be monitored in real time via the display on the control panel.
4.End of trial.
After the test time reaches or reaches the set temperature range, press the stop button of the test chamber and the test chamber will stop heating or cooling.
After waiting for the temperature in the test chamber to return to room temperature, you can open the test chamber door and take out the tested product.
3. Precautions.
1.Ensure that the area around the test chamber is well ventilated to avoid affecting the heat dissipation effect of the test chamber.
2.Before operating the test chamber, it is necessary to understand the performance and test requirements of the product under test, and set the appropriate temperature parameters according to the requirements.
3.When setting the temperature parameters, the parameters such as heating rate, cooling rate and holding time should be determined according to the specifications and test requirements of the tested product.
4.During the test, the temperature change of the test chamber should be checked regularly and the relevant data should be recorded for subsequent analysis and reporting.
5.After the test, the test chamber should be cleaned up in time to keep the test chamber clean and operational.
4. Common problems and solutions.
1.The temperature in the test chamber is unstable.
Possible cause: The temperature of the surrounding environment of the test chamber changes greatly, resulting in temperature fluctuations in the test chamber.
Solution: Place the test chamber in a stable environment to avoid external temperatures.
2.The chamber could not be started.
Possible cause: The power supply of the test chamber is not connected or the switch is turned off.
Solution: Check whether the power plug of the test chamber is plugged in tightly and whether the switch is turned on.
3.The heating or cooling effect of the test chamber is not good.
Possible cause: Improper placement of fixtures inside the test chamber, resulting in uneven temperature distribution.
Solution: Reposition the fixture to ensure that the product is in good contact with the sensor in the test chamber.
5. Summary. The operation of the high and low temperature damp heat test chamber needs to follow a series of processes and precautions to ensure the accuracy and reliability of the test.
