Precautions for Using the Temperature Humidity Chamber

A qualified temperature humidity chamber needs to be used correctly in order to obtain reliable test results. Correct operation and careful maintenance are important means of prolonging the service life of any temperature humidity chamber, as there will always be some faults and problems during the long-term operation. For each specific test chamber, the manufacturer will be attached to a thick operation and maintenance manual to guide the user to use the equipment correctly, which is any temperature and humidity test chamber holders must follow the principles of use.

Here is the content list:

• Switching the chamber on and off

• Inspection and observation during use

• The correct handling of sudden failures in use

Switching the chamber on and off

The operating instructions for the temperature humidity chamber will detail the procedures for switching on and off. Check whether the pressure gauge at the compressor inlet and outlet is normal. The pressure indicated in the gauge before switching on is the static equilibrium pressure, which may vary slightly depending on the ambient temperature, but the difference is not too great.

The operating procedures are listed in the temperature humidity chamber shutdown steps, first stop, then turn off the water, and then power off. But the operator often ignores a problem, that is, in the test program settings, when the test program completes the last step of the settings, should be added to the set step program to allow the temperature humidity chamber slowly back to the ambient temperature and humidity state, rather than in the high or low-temperature state suddenly shut down.

Inspection and observation during use

The temperature humidity chamber usually operates automatically according to the given test program, so that the operator does not have to be completely present at the test site. However, no automated operation and perfect alarm protection can ensure that unexpected failures may occur during operation, so the operator must insist on inspection and observation of the temperature humidity chamber in operation.

Not every test chamber is fully equipped with all kinds of observation means, because of the requirements of noise isolation, some of the observation means may be closed by the partition and inconvenient to observe. However, any temperature humidity chamber will always be configured with some means of observation, the operator should be given in accordance with the manufacturer's operating instructions for the equipment, make full use of and explore these external observation resources to ensure the normal operation of the test chamber, to ensure the credibility of the test.

The correct handling of sudden failures in use

With the progress of technology, temperature humidity chamber automation degree of operation is becoming more and more perfect, fault diagnosis, self-detection, and protection alarm systems are also increasingly complex, and the test chamber components of the operating parameters deviate from the set range of values, the control system will be implemented to protect the alarm and stop. After this, the operator should base on the reasons for the protection alarm, timely find the source of the fault, and into the automated operation of the test chamber, the alarm and stop the majority of the way through the relay to cut off the power supply electric line disposal after the start of operation again.

The above are some of the problems easily encountered in the use of a temperature humidity chamber. We hope it is helpful in the future use.
