Since the point A of this circuit sensor VD2 negative end potential design is 1 0 ℃, and V head is 0 V and it shows 00.0 , so the circuit uses3kΩ RP3. The pin 30 of theintegrated circuit 7170 is connected to the ground (shown in play x place). It makes the potential Vin of the head increase 1V. When commissioning VD2 sensor is in the ice water mixture, the potentiometer RP3 makes the head show 00.0 . Put the VD2 in boiling water, and the RP4 potentiometer makes the head show 100.0 , the debugging is brought to an end.
