1. The ambient temperature of the constant temperature and humidity test chamber should be maintained between 5 °C and +30 °C (average temperature within 24 hours ≤ 30 °C); humidity ≤ 85% RH (air conditioning should be turned on during summer use); and ventilation should be good, so that The compressor can dissipate heat normally.

2.the voltage in the workplace must be stable. If the voltage is unstable, the current will be too large or too small. Long-term operation under such conditions will cause great damage to the compressor. Xiaobian recommends using a voltage regulator to link the test chamber to run.

3. The working temperature of the constant temperature and humidity test chamber is too much, and the surface of the compressor needs to be kept clean.

4. Do not start the compressor frequently during the test, the start interval is 15 minutes.

The constant temperature and humidity test chamber pressure is not only the maintenance of the shrinking machine, but also the maintenance of other parts in daily use, so as to ensure the performance and service life of the equipment.
