Meter AC Voltage Accuracy and Frequency Response Test

To prevent possible electrical shock, fire, or personal injury, ensure that the
calibrator is in standby mode before making any connection between the
calibrator and the Test Tool. Dangerous voltages are present on the calibration
source and connection cables during these steps.
To test the ac voltage measurement accuracy:
1. Connect the Test Tool to the 5502A. See
