Warning
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
.
2. Select the Test Tool setup.
3. Press

.
8. Set the 5502A to source the appropriate ac voltage.
9. Observe the reading and check that it is within the range shown under the appropriate
column.
10. Continue through the test points.
When you are finished, set the 5502A to 0 (zero) Volt and Standby.
