The 500V and 1250V range will be tested in Section 4.5.14
2)
Due to calibrator noise, occasionally OL (overload) can be shown.
4.5.10 Input A and B AC Voltage Accuracy 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 Input A and B AC Voltage accuracy:
1. Connect the test tool to the 5500A as for the previous test (see Figure 4-5).
