Title:
VOLTAGE MEASURING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/087992
Kind Code:
A1
Abstract:
Disclosed is a configuration for measuring a signal voltage by means of a voltage measuring unit (2) via a multiplexer (1), to which signals transmitted from a plurality of sensors, including a thermistor (3), are inputted. The configuration is provided with a series circuit (6), which is connected between a power supply and the ground, and which includes the thermistor (3), a drive resistor (Rd), and a level shift resistor (R1). A common connection point of the drive resistor (Rd) and the level shift resistor (R1) is connected to an input terminal (Sin0) of the multiplexer (1).
