DIRECT CURRENT VOLTAGE FUNCTION CALIBRATION DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2017/164502
Kind Code:
A1
Abstract:
The present invention relates to a direct current voltage function calibration device for a multi-function meter and a meter calibrator. The direct current voltage function calibration device for a multi-function meter calibrator, according to the present invention, comprises: a first meter calibrator calibrated to a reference value with respect to a reference point and having a first plus terminal and a first minus terminal; a second meter calibrator calibrated to a reference value with respect to a reference point and having a second plus terminal and a second minus terminal, which is connected to the first minus terminal; a digital multi-meter having a third plus terminal, which is connected to the first plus terminal, and a third minus terminal, which is connected to the second plus terminal; and a direct current voltage calibration circuit for performing control so as to calibrate direct current voltages with respect to other points through an up-conversion or a down-conversion of a voltage value by using the digital multi-meter on the basis of the reference values set in the first meter calibrator and the second meter calibrator.
