Because the high-precision instruments such as constant temperature and humidity chambers are relatively large in size, it is inconvenient to move or move, and the circuit is complicated. When a fault occurs, it is often difficult for the user to start. In order to promptly judge the fault and solve it by himself, Suzhou Xinda Test Equipment Co., Ltd. introduces six major fault repair and repair solutions for constant temperature and humidity test chambers. 1. When the temperature and humidity controller shows abnormal humidity Checking steps: 1. Please check the under-water over-temperature protector of the control room, whether it is set at 150 °C; 2, please check the machine room, whether the pipeline is too dirty, causing the water flow is not smooth; 3. Please check if there is water in the water tank. If it is not water, check whether there is water in the tank. 4. Please check if the solid state relay in the humidity part is burnt out. If the heater is not burnt, please use the three-meter electric meter AC voltage file, the voltage gear position is opened to 600 volts, and the red and black rods are respectively marked with the line number. The solid state relay of h is on both sides of the AC, and the humidity setting value of the humidity part is set to 0%. At this time, the indicator of the solid state relay of the humidity part will not light up, if the measured voltage value does not change, maintain Below 10v, the solid state relay burns out and presents a short circuit condition. Or set the humidity part setting to 0% first, and then see if the water in the humidification tank in the machine room is boiling. Solution: 1. If not, please turn the water over temperature protector to the position of 150 °C; 2. Please turn off the main power supply at the rear of the machine, then open the drain valve under the humidifying bucket to the position parallel to the pipeline. When the water in the water tank is drained, use the wrench to open the humidifying bucket. Internally, the scale is removed due to long-term humidity. Then remove the silicone tube and wash it in the water. After maintenance, follow the removal method and put it back in the opposite direction. After the device is finished, close the drain valve under the humidification tank to the tube. The vertical position of the road, and then turn on the main power supply behind the machine; 3, the upper and lower water tanks are all water, please add water to the water tank, you can solve. If there is no water in the water tank, there is water in the water tank, then the water pump in the water tank is broken. Please inform Suzhou Xinda constant temperature and humidity maintenance customer service department to go to the door for maintenance; 4. Please replace the solid state relay of the humidity part (the solid state relay marked with h as the line number), or inform the Suzhou Xinda maintenance department to go to the door for maintenance.
