Section 4: Working Principle

The temperature sensor receives the temperature signal, which is then fed into an amplifier. Through an analog switch, the signal is converted to digital via A/D conversion and input into the temperature control meter. The PID program runs to provide the corresponding refrigeration parameters, controlling the compressor's refrigeration time to achieve temperature control. This ensures the test is conducted safely and reliably, thereby guaranteeing the safety and reliability of the test.
