4.8.2 Meter AC Voltage Accuracy & Frequency Response Test
Warning
Dangerous voltages will be present on the calibration source
and connecting cables during the following steps. Ensure that
the calibrator is in standby mode before making any connection
between the calibrator and the test tool.
Proceed as follows to test the ac voltage measurement accuracy:
1. Connect the test tool to the 5500A as for the previous test (see Figure 4-18).
2. Select the following test tool setup:
• Press
• Press
to open the Measurement menu, and select V ac
• Press
to select MANUAL ranging; use to select the ranges
3. Set the range to the first test point in Table 4-13.
4. Set the 5500A to source the appropriate ac voltage.
5. Observe the reading and check to see if it is within the range shown under the
appropriate column.
6. Continue through the test points.
7. When you are finished, set the 5500A to 0 (zero) Volt, and to Standby.
