NAVY CALIBRATION PROGRAM INSTRUMENT CALIBRATION PROCEDURE AQ- 21 DC OR AC (60 CPS) VOLTAGE OR CURRENT INDICATING INSTRUMENT (USING THACH POWER SUPPLY AND RAH 1605)

摘要

This procedure describes the calibration of direct and alternating (60 cps) voltage and current indicating instruments.nThe measurement range of this procedure is limited to the output of the power supply and/or the ranges of the ac-dc transfer standard.nThe calibration of the Test Instrument is performed by comparing the indications of the Test Instrument to the equivalent voltage or current indications of the ac-dc transfer standard. The power supply is used to provide the required voltage or current to the two instruments.
