If a fault problem occurs, the quick maintenance can be carried out through the result. And inputting and selecting data through the touch screen, and extracting the input data. The main control board 11 is then input into the PID temperature control table 12 in the form of programmed data and is simultaneously set to the target temperature. Then, in the heating process, the PID temperature control meter 12 controls the on and off of the relay (solid state relay) 18 in a signal on-off mode, the measured temperature of the PT100 thermal resistor is used as signal feedback, when the temperature is lower than the set temperature, the relay 18 is closed, the PT100 thermal resistor is always conducted for heating, and when the temperature is higher than the set temperature, the relay 18 is opened, and the heating power supply loop of the PT100 thermal resistor is disconnected.
