Abstract

PURPOSE:To check the constitution of a circuit simply by forming a control circuit for controlling an input to an analog/digital (A/D) conversion circuit so as to be switched from the output of a pressure sensor to the output of a reference signal generating circuit by the operation of an external operating member. CONSTITUTION:The output of the pressure sensor 1 is inputted to the control circuit 3 and the output of the reference signal generating circuit 2 is also inputted to the circuit 3. The output of the circuit 3 is inputted to the A/D conversion circuit 4 and the analog value is converted into a digital value. The converted digital value is inputted to a display control circuit 5 and decoded into a display signal to be displayed on a display device 6. When the external operating member 8 is operated in accordance with a previously determined operation, a control signal is outputted from a chattering preventing circuit 7 and the control circuit 3 is switched to input the signal from the circuit 2 to the circuit 4, so that the reference signal is displayed.
