Abstract

PURPOSE: To increase the accuracy of divided voltage, by connecting the return resistor having the same resistance as the resistor network and the reference potential of the opposite polarity as the resistance network via the interlocking switch to the connection point between the voltage division resistance network and ground wiring.
CONSTITUTION: One end of the voltage division resistance network RG is connected to the reference voltage Vref of positive or negative polarity via the switch S1, and another end is connected to the ground potential via the ground resistor (r). Further, at the connection point T1 between the resistance network RG and the ground resistance (r), the reference voltage Vref of the opposite as that given to the resistance network RG is connected via the return resistor R' of the same resistance value as the resistance network RG and the switch S2 in interlocking with the switch S1. Thus, the potential at the connecting point T1 is the same as ground potential and the current flowing to ground GND is absent.
