3 Overview

Calibrator is a versatile standard electrical signal output means, according to the provisions of the accuracy of the output DC voltage, respectively, AC voltage, DC current, AC current, frequency and DC resistance and other signals. Mainly used for correlation detection instrument. Calibrator primarily by the signal generating unit, an amplifier, power supply and protection unit, range unit, AC/DC single Yuan, A/D unit, display unit and standard resistors and other components.
