5. When the temperature and humidity controller is running, the actual humidity value is always displayed at 100%. Checking steps: 1. The air in the constant temperature and humidity chamber is very dry: 1). Check the dry and wet ball fixed seat part of the sink first, whether there is water; 2). Please check the dry and wet ball holder inside the test box to sense the wet ball. The wet ball gauze hanging on the part of the device is wet at the part of the sensor; 2, the air inside the box is very humid (humidity may not reach 100%, but has been high): first set the humidity part set value to 0%, then look at the humidification barrel in the machine room whether the water is boiling. solve: 1. The air inside the box is very dry: 1). If it is not water, please adjust the water level cup in the machine room, which is located on the top, or check whether the pipeline between the water level cup and the wet and dry ball holder is blocked. After adjustment, please Use a cloth to drain the water and make sure the water goes in all the way. 2). If there is no wetness, please change the gauze. (It is recommended to replace the gauze once a month.) If the temperature is high and high humidity, the number of replacements needs to be more. If only the temperature conditions are used, the gauze can be taken out and the life is extended. After being taken out, it can be soaked in alcohol and has prolonged its life; 2. If there is boiling, please replace the solid state relay of the humidity part (the solid state relay marked with H as the line number). 6. When the temperature and humidity controller is running, the actual humidity value can not reach the set value, and the humidity is actually The value is much lower than the humidity setting Checking steps: 1. Check whether the solid state relay of the constant temperature and humidity test chamber is burned and broken. If the heater is not burned, please use the AC voltage file of the meter, and the voltage gear is opened to 600 volts, and the red and black rods are placed on the line respectively. The solid state relay marked with H is on both sides of the AC, and the humidity setting value of the temperature part is set to 100%. At this time, the indicator of the solid state relay of the humidity part will light up, if the measured voltage value does not change, Maintaining at 220V or 380V means that the solid state relay is burned and shows an open state; 2. Check if the fuse is burnt; 3, check whether the humidification barrel heater burned: cut the two lines of the humidification barrel heater, use the three-meter ohms file, measure the resistance value, if the resistance is infinite, it means the heater burned. solve: 1. Replace the solid state relay of the humidity part (the solid state relay marked with H as the line number) 2.
