3. Check the over-temperature protector in the high and low temperature humid heat alternating test box: When the high and low temperature humid heat alternating test box is in operation, set the maximum value of the over temperature protection plus 20 ℃ ~ 30 ℃. When the temperature in the test chamber rises to the over-temperature protection set point, the heater power supply stops, the over-temperature warning light is on but the fan is still running, if it is running for a long time and is unattended, please make sure to check the over-temperature protector Set up properly.

V. Replacement of wet-bulb test cloth in high and low temperature wet heat alternating test box: When the surface of the test cloth is not clean or hard, or after the temperature control is completed, the test cloth must be replaced before continuing the temperature and humidity sphericity control. The test cloth should be replaced every three months. The temperature measurement body should be wiped with a cleaning cloth when replacing. The new test cloth should be cleaned first.
6. Inspection and adjustment of the wet bulb water level of the high and low temperature humid heat alternating test chamber: The water level of the accumulator should not be too high, so that the water overflows the accumulator or is too low to make the wet ball test cloth absorb water abnormally, affecting the accuracy of the wet ball Just keep six points full. The water level of the water tube can be adjusted to adjust the height of the water box. In summary, only correct cleaning and maintenance can make the high and low temperature humidity heat test chamber exert its best performance and maximum function.
