Precautions for Cold and Hot Alternating Aging Box

1. The inspection and adjustment of the wet bulb water level in the high and low temperature alternating humidity test chamber should not be too high in the water tank, causing water to overflow from the tank or too low, resulting in abnormal water absorption of the wet bulb test cloth and affecting the accuracy of the wet bulb. The water level should be kept at about six tenths full. The adjustment of the water level in the water tank can adjust the height of the water tank.

2. The replacement of the wet bulb test cloth in the high and low temperature alternating humidity test chamber is necessary when the surface of the test cloth is not clean or hardened, or before continuing to perform temperature and humidity bulb control after completing temperature control. The test cloth should be replaced about every three months. When replacing, the temperature sensor (Sen sor) should be wiped with a clean cloth. When replacing the new test cloth, it should be cleaned first.
3. The condenser of the high and low temperature alternating humidity test chamber should be regularly maintained every month to remove the dust attached to the condenser cooling mesh using a vacuum cleaner or high-pressure air spraying.
4. During the operation of the high and low temperature cyclic testing machine, the setting of the over temperature protection in the high and low temperature alternating humidity test chamber should be increased by 20 ℃~30 ℃. When the temperature inside the test chamber rises to the set point for over temperature protection, the power supply to the heater stops, and the 'OVERHEAT' over temperature warning light lights up but the fan still runs. If it runs for a long time without supervision, please make sure to check the over temperature protector before operation to ensure that it is properly set (the wet bulb over temperature protector is set to 120 ℃).
