Structural analysis and maintenance of high and low temperature damp heat test chamber（2）
5. When high and low temperature damp heat test chamber the humidifying barrel enters the water pipe, the remaining air must be completely discharged to prevent water from entering.
Special attention: After the machine has completed low-temperature operation, be sure to set the normal temperature condition (30±5℃) so that the temperature in the box will be at normal temperature when high and low temperature damp heat test chamber the machine is shut down, so as not to affect the freezing phenomenon caused by the low temperature in the box, and the window glass Fogging phenomenon.
6. During the operation, please do not open the door of the box unless it is necessary for good quality, otherwise it may cause the following undesirable consequences:
－ It is very dangerous for high temperature and humidity to rush out of the box.
-The inside of the door is still hot, causing injury.
-High temperature air may trigger a fire alarm and cause malfunctions.
7. high and low temperature damp heat test chamber Please note that the machine must be grounded safely and reliably, and the Guangdong high and low temperature test chamber can avoid electrostatic induction.
8. Avoid turning off and on the freezing unit within three minutes.
9. If heating samples are placed in the box, please use an external power supply to control the power supply of the sample. Do not directly use the power supply of the machine in the low-temperature test box.
10. Circuit breaker, high and low temperature damp heat test chamber temperature over-temperature protector, provide the test product of this machine and the safety protection of the operator, so please check it regularly.
11. The gauze with high and low temperature damp heat test chamber the correct wet ball device can guarantee the correct relative humidity.
12. Excellent test of explosive, flammable and highly corrosive substances is prohibited.
13. Please read the high and low temperature damp heat test chamber controller manual and related manuals carefully before operating the constant temperature and humidity machine.
