When the temperature and humidity controller of the high and low temperature test chamber shows abnormal temperature: please check whether the over-temperature protector of the control panel is set at the position of 150 ℃. Check whether the circulating motor in the equipment room is damaged or not running.
Please check whether the solid-state relay in the temperature part is burned out and short-circuited. If the heater is not burned out, please use the AC voltage range of the three-meter meter. The voltage range is turned to 600 volts. Place the red and black bars on the line marked with T. On both sides of a solid state relay, set the temperature setting value of the humidity part to 0 ° C. At this time, the indicator light of the solid state relay of the temperature part will not light up. If the measured voltage value does not change, it is maintained below 10V It means that the solid-state relay is burned and short-circuited.
The temperature control instrument of the high and low temperature test chamber uses imported instruments, with PID adjustment, SSR output, fast auto-tuning, digital display, and convenient reading. The box door, working room and shell are equipped with high temperature resistant sealing strips and pressing devices, which can effectively ensure the sealing and thermal insulation performance of the box body. The French "Taikang" original fully enclosed compressor used in the refrigeration system ensures the low temperature stability of the high and low temperature test chamber. The high and low temperature test chamber has over-temperature protection, overload protection of the control circuit, short-circuit protection, safe and reliable use. The studio and sample rack are made of stainless steel, and the outer box is made of high-quality cold-rolled steel plate with beautiful appearance.
