The constant temperature and humidity test appears to be mainly reflected in the four aspects of power supply voltage, ventilation, frequent start-up and environment.

1. Power supply voltage: The voltage of the workplace of the constant temperature and humidity test chamber must be stable. If the voltage is unstable, the current will be too large or too small. In this environment, long-term operation will cause great damage to the compressor. Therefore, use a voltage regulator to link the test chamber to ensure voltage stability.

2. Ventilation: The working environment should ensure that the ventilation is good and there is no dust, and the compressor should be cleaned frequently. If the test box is not used for a long time, it should be placed in a dust-free space.

3. Do not start frequently: Do not start the compressor frequently during the process of using the constant temperature and humidity test chamber. The interval between the compressors of the constant temperature and humidity test chamber should be more than 15 minutes.

4, the use of the environment: the ground level, good ventilation, in the absence of flammable, explosive, corrosive gases and dust, and there is no strong electromagnetic radiation source around.

Ambient temperature: 5 ° C ~ +30 ° C (average temperature within 24 hours ≤ 30 ° C); ambient humidity: ≤ 85% RH.

The above is a point about the maintenance of the constant temperature and humidity test chamber, I hope to help everyone.
