AN AC MEASUREMENT STANDARD, DESIGNED FOR CALIBRATION APPLICATIONS. THE INSTRUMENT HAS FOUR SETS OF INPUT TERMINALS, TWO TYPE N AND TWO SETS OF FIVE-WAY BINDING POSTS. ONE TYPE N AND ONE SET OF BINDING POSTS ARE DEDICATED TO THE AC MEASUREMENT AND TRANSFER MODES. AN ELECTRICAL TESTING DEVICE IS PLUGGED INTO THE MEASUREMENT STANDARD AND THE ELECTRICAL MEASUREMENTS COMPARED. ADJUSTMENTS CAN THEN BE MADE TO THE DEVICE UNDER TEST TO ENSURE ACCURACY. WHETHER IT IS USED AS A VOLTMETER OR TRANSFER STANDARD, INPUT VOLTAGE AND FREQUENCY ARE ALWAYS INDICATED ON THE MEASUREMENT DISPLAY. IN TRANSFER MODE, THE AC/DC OR AC/AC DIFFERENCE IS ALWAYS INDICATED ON THE CONTROL IN PPM, PERCENTAGE VOLTS OR RATIO. THE INSTRUMENT COVERS AN ALTERNATING VOLTAGE RANGE OF 700 MICRO VOLTS TO 1000 V AND A FREQUENCY RANGE OF 10 Hz TO 1 MHz. A WIDEBAND VOLTAGE OPTION EXTENDS THE FREQUENCY RANGE TO 30 MHz. IT IS ALSO COMPATIBLE WITH CURRENT SHUNTS TO PERMIT AC/DC CURRENT TRANSFER MEASUREMENTS UP TO 20 A.
