More Information
Summary:A voltage measurement system includes: a first reference signal transmission device (communication device) including a first master oscillator that generates a first master clock signal and a first reference signal generation circuit that generates a first reference signal based on the first master clock signal; and a first voltage measurement device including a first slave oscillator, a first correction circuit that corrects an oscillation frequency of the first slave oscillator based on the first reference signal, and a first voltage measurement circuit. The voltage measurement system includes: a normal mode; and a correction mode in which the first reference signal is transmitted from the first reference signal transmission device (communication device) to the first voltage measurement device, and the oscillation frequency of the first slave oscillator is synchronized with an oscillation frequency of the first master oscillator using the first reference signal.
