The high configuration of the constant temperature and humidity test machine, in the transportation process and assembly process are specified points. In the process of use, the operator will follow the test requirements and test samples for reasonable test, but in the operation of the test situation, and inevitably there will be some small problems. How to quickly and efficiently solve the test problems, normal and smoothly into the test state, the test is the operator's improvisation and solid foundation ability.

In the process of operation, the temperature and humidity controller operation process and can not reach the pre-set range of values and the actual humidity value of the test machine is lower than the set value of many cases, how to deal with it, first of all, the operator should check the circuit failure, whether there is a burnt line and thus short-circuit phenomenon, whether the heater is intact, but also need to adjust to the position of the AC voltage meter and Set the voltage level to 600V and place the red and black detection rods on both sides of the solid state relay AC labeled H and the temperature setting of the temperature section should be set to 100% and the indicator light of the temperature section of the solid state relay will light up if there is no change in the measured voltage value and it is maintained at 220V or 380V.

Constant temperature and humidity testing machine under normal test conditions, the temperature range is very important to set the same impact on the normal conduct of the test power cord and the internal system of the circuit need to be checked regularly, after checking the error-free to ensure that the test after the abnormal conditions are reduced.
