The high and low temperature alternating humidity chamber can simulate a climate environment with a combination of temperature and humidity, in order to test the performance of products in different environments. As a precision instrument, the high-low temperature alternating humidity chamber requires operators to master the following operating essentials to ensure the normal use of the instrument:

1、 When using a high and low temperature alternating humidity test chamber, it is necessary to ensure that it is grounded safely and correctly to avoid static electricity induction.

2、 During the operation of the box, do not touch it with your hands for inspection, otherwise there is a risk of electric shock or injury from the fan, resulting in danger.

3、 When operating the high and low temperature alternating humidity chamber, avoid shutting down and restarting the refrigeration unit within fifteen minutes.

4、 The installation position of wet bulb gauze must be accurate in order to measure the correct relative humidity.

5、 The lighting of the test chamber should be turned off at all times except when necessary.

6、 Circuit breakers and over temperature protectors provide safety protection for instrument test products and operators, so please check them regularly.

7、 When the low-temperature operation is completed and the temperature is at 60 ℃, dry for about 30 minutes before opening the box door to avoid affecting the measurement time during subsequent tests or causing the evaporator to freeze.

8、 Non local operators are not allowed to perform maintenance and inspection on the machine And during the inspection, in addition to having dedicated personnel, there should also be professional electricians and circuit maintenance personnel to prevent uninformed personnel from turning on and off the power, thereby posing a risk of electric shock.

Fully mastering the operating essentials of the high and low temperature alternating humidity chamber mentioned above, and using the instrument reasonably, can maximize the effectiveness of the instrument.
