Maintenance Method of Constant Temperature and Humidity Electronic Test Chamber
Maintenance method of constant temperature and humidity electronic test chamber:
1.Before the test, be sure to check that the water level in the water tank is not too high or too low. If the water overflows the water tank or is too low, the wet ball test cloth will not absorb water properly, and the accuracy of the wet ball will be affected. The water level can be kept about six minutes full. The water level of the water tank can be adjusted to adjust the height of the water tank. You need to check and add water almost every two or three tests. You can see the water pipe in front to replenish the water. The machine will alarm and stop working when there is no water.
2.If the machine is operated below 0 ℃, avoid opening the door of the box as much as possible, because at low temperature, if the door is opened, frosting of the internal evaporator and other parts is likely to occur, especially the lower the temperature, the worse Must be opened, the door opening time should be minimized.
3.When the temperature test box has completed low-temperature operation, be sure to set the temperature to 60 ° C and perform the drying process for about half an hour, so as not to affect the measurement time or freezing phenomenon of the next working condition.
4.The radiator (condenser) of the freezer should be regularly maintained and kept clean.
5.The humidifier barrel's water inlet pipe must completely exhaust the remaining air to prevent water from entering. After the machine finishes running at low temperature, it is necessary to set the normal temperature condition (30 ± 5 ℃) so that the temperature in the box will be normal temperature when the machine is stopped, so as not to affect the freezing phenomenon caused by the low temperature in the box and the fogging of the window glass .
6.During operation, unless absolutely necessary, please do not open the door of the box, otherwise it may cause the following adverse consequences:
－High temperature and humidity rushing out of the box is very dangerous for the operator.
－The inside of the door is still hot, which is easy to cause injury.
- Hot air may trigger a fire alarm and cause incorrect action.
7.Please note that the automobile rain testing chamber must be grounded safely and securely to avoid static induction.
8.Avoid turning off and on the freezing unit within three minutes.
9.If a hot sample is placed in the box, please use an external power supply for the sample power control. Do not use the power supply of the machine directly.
10.Circuit breakers and temperature over-temperature protectors provide safety protection for the test products of this machine and the operator, so please check regularly.
11.The correct installation of wet ball gauze can only ensure the correct measurement of relative humidity.
12.Testing of explosive, flammable and highly corrosive substances is absolutely forbidden.
13.Please read the controller manual and related manuals before operating the constant temperature and humidity machine.
