How high and low temperature maintenance <br> <br> constant temperature and humidity testing machine to be used with the process, there are many considerations, but also often need maintenance, so you can extend the life of the chamber, the testing machine. Note Matters and constant temperature and humidity test chamber maintenance 1. Before the test, be sure to check that the water level of the water tank is not too high, nor too little. If the water overflows the water trap or is too low, the wet bulb test cloth absorbs water abnormally, which affects the accuracy of the wet bulb. The water level is about six minutes. The water level of the water reservoir can be adjusted to adjust the level of the water tank. It is necessary to check almost every two or three tests and add water. You can see the water pipe in front to make up the water. If there is no machine, the machine will alarm and stop working.
2 If a hot sample is placed in the box, use the external power supply for the sample power control. Do not use the power directly.
3 This machine is equipped with a test hole on the machine side, which can be used when connecting to the test line in the box.
4When the humidifier is filled into the water pipe, the remaining air must be completely discharged to prevent water from entering. Constant temperature and humidity test chamber maintenance
5 If the machine is running below 0 °C, it should be avoided to open the door as much as possible. If the door is opened, it is easy to cause the internal evaporator and other parts to seal the ice. Especially the lower the temperature, the more serious the situation is. Must be opened, you should try to shorten the opening time.
6 When the low temperature operation is completed, it is necessary to set the temperature condition at 60 ° C for about half an hour to avoid affecting the measurement time or icing phenomenon of the next working condition.
7 circuit breaker, temperature over-temperature protector, provide the test products of this machine to the operator's safety protection, so please check regularly.
8. It is absolutely forbidden to test explosive, flammable and highly corrosive substances.
9 If you want to observe the change in the box during the test, you can turn on the LIGHT switch and know the internal changes through the window.
10 Please note that the unit must be grounded safely and reliably to avoid static induction.
11 Avoid turning off and turning on the freezing unit within three minutes.
12 The radiator (condenser) of the freezer should be regularly maintained and kept clean.
13 In operation, unless absolutely necessary, please do not open the door, otherwise it may lead to the following adverse consequences: - high temperature moisture is dangerous to drive out of the box. - The inside of the door is still holding high temperature and causing injury. - High temperature air may trigger a fire alarm and cause a malfunction.
14. Properly install the gauze of the wet ball to ensure the correct relative humidity.
15. Please read the controller manual and related manuals before operating the constant temperature and humidity machine.
