Calibration Information
Performance Tests
When calibrating or measuring AC current, avoid the potential for errors from coupled noise, by either:
1. Shorting the VeG to the COM input
or
2. Having NO connection to the VeG input.
1. Set the UUT Rotary Switch to the position called for in Table 2 (175) or Table 3 (177/179), and for all
measurements other than current (amps), connect the calibrator to the VeG and
If testing the milliamps function, connect the calibrator to the Meter
terminals.
If testing the amps function, connect the calibrator to the Meter
2. Referring to Table 2 or Table 3, apply the indicated calibrator output voltages to the UUT for each test.
3. Verify that the UUT displays a reading that is within the limits shown in the Meter Response column.
