The high and low temperature test box is a kind of environmental test equipment.
The more common environmental equipment are constant temperature and humidity box, high pressure aging test box, shower test box and so on
.
There are many precautions in the use of high and low temperature test chambers, and frequent maintenance is required to prolong its service life
.
Here are some precautions when using it
.
1.
Before doing the test, the water level in the water tank should be adjusted to a medium level
.
If the water level is too high, it will cause the water to overflow
.
If it is too low, the water absorption of the wet bulb test cloth will be abnormal
.
Under normal circumstances, the water level of the tank should be kept at 6
.
Water level sign
.
By adjusting the height of the reservoir, the water level of the reservoir can be adjusted
.
Basically, after two or three tests are done, an inspection needs to be done
.
When a colleague adds water, he can look at the water pipe in front to add water
.
When not present, the machine alarms and stops working
.
2.
The machine has a test hole on the strategy that can be used when it is connected to the test circuit in the box
.
If you want to observe the changes in the box, you can turn on the light switch in the room and see the changes in the room through the window
.
3.
If the machine is used below 0°C, the door should be avoided
.
This is because when the temperature is low, if the door is opened, it is easy to cause the internal evaporator and other components to freeze, especially the temperature reading
.
it gets worse
.
If the door must be opened, the opening time should be shortened as much as possible
.
4.
After the low temperature test is completed, be sure to set the drying temperature at about 60°C for half an hour, so as not to affect the measurement time or freezing of the next test
.
5.
The radiator of the refrigerator should be regularly maintained and kept clean
.
6.
When the humidifying bucket enters the water pipe, it must be completely discharged from the remaining space to prevent water from entering
.
