Troubleshooting: After analysis by professionals of constant temperature and humidity test chamber manufacturers, the constant temperature and humidity test chamber is a low temperature constant temperature and humidity test chamber. The temperature is controlled by imported instruments to control the heating tube and the refrigeration compressor to achieve the purpose of temperature control. The constant temperature and humidity test chamber is unstable at high temperature, analyzed in principle, Professionals of Beijing Yashilin manufacturers made the following analysis: 1. In the constant temperature and humidity box in the high temperature test, if the temperature change does not reach the test temperature value, you can check the electrical system and troubleshoot one by one. If the temperature rises very slowly, it is necessary to check the wind circulation system to see if the adjustment baffle of the wind circulation is opened normally, otherwise, check whether the motor of the wind circulation is operating normally. If the temperature overshoot is severe, then the PID setting parameters need to be adjusted. If the temperature rises directly and the over-temperature protection, then the controller fails, the control instrument must be replaced. 2. The heating of the constant temperature and humidity test chamber is not controlled, whether the instrument display or control is normally repaired or replaced; whether the instrument setting is correct or whether it is a manual output, and whether the actuator contactor and relay contact are stuck or burned or thyristor Whether the solid state relay is broken down and replaced; whether the heating tube and heating wire of the actuator are repaired to the ground or whether the control of the controller, regulator and electric contact thermometer is good or whether it is burned or damaged or repaired or replaced by experts in the industry Throwing Trainer bands Our fitness products can be used individually or grouped, giving a rigorous workout regardless of your skill level.
