Calibration of the voltage standard is indispensable in the electricity, electronic, and automobile industries which have an industrial Japanese basis. The automation system for the calibration of the multi-function-calibrator for which the direct current voltage generating device being used widely in the industrial world, based on 10V of the standard voltage generation vessel calibration with upper organization, was developed. And a digital-multi-meter is calibrated by using the multi-function-calibrator.

We were able to evaluate all the calibration values of the multi-function-calibrator and digital-multi-meter to within 1ppm standard deviation. A comparison with the usual manual calibration value showed that it corresponded within 1ppm, so we were also able to confirm the validity of software to automate calibration of the direct current voltage.
