Precautions for using high and low temperature alternating test chambers

The series of high and low temperature alternating test chamber is suitable for aerospace products, information electronic instruments, materials, electrical engineering, electronic Products, Various electronic components are tested for their various performance indicators in high and low temperature environments. Pay attention to the following problems during use: rGDTextile Testing Instruments, Testing Equipment Manufacturer
When the high and low temperature alternating test chamber is operated below 0°C, try to avoid opening the door, because at low temperature, the door will be opened When the door is opened , it can easily cause internal evaporator The phenomenon of freezing and other parts, especially the lower the temperature, the more serious the situation When there is a need to open the door, the opening time should be reduced as much as possible. Before testing, make sure that der the water level in the reservoir is neither too high nor too low. If the water overflows the storage tank or is too low, the wet bulb test cloth will not absorb water normally, which will affect the accuracy of the wet bulb. Just keep the water level around 60% full. Adjusting the water level of the storage tank can adjust the height of the storage tank. After almost every two or three tests, you need to check and add water. You can see the water pipe in front to refill water. If there is no water, the machine will alarm and stop working. rGDTextile Testing Instruments, Testing Equipment Manufacturer

When the humidifier barrel enters the water pipe, the retained air must be completely released to prevent water intrusion to prevent . Special Attention: After the machine running at low temperature, make sure the normal temperature condition (30 ± 5 ° C) is adjusted so that the temperature inside the box is at normal temperature when stopped, so as not to affect the freezing phenomenon caused by the low temperature inside the box and the window glass fogging phenomenon. When a heating sample is placed in the box, please use an external power supply to control the sample power supply, and do not directly use the local power supply of the high and low temperature alternating test box. rGDTextile Testing Instruments, Testing Equipment Manufacturer

The cooler (condenser) of the high and low temperature alternating test chamber should be serviced regularly and kept clean. When the low-temperature operation is completed, be sure to set the temperature condition to 60°C and carry out a drying treatment for about half an hour so as not to affect the measurement time or the freezing phenomenon of the next operation condition. open the doorduring operation unless absolutely necessary, otherwise this may lead to the following adverse consequences:rGDTextile Testing Instruments, Testing Equipment Manufacturer
