3-34. AC Current Amplitude Accuracy
The AC Voltage Amplitude Accuracy test verifies the accuracy of ac current at the
5500A Calibrator front panel AUX terminals. Use a Fluke 5790A with the appropriate
precision shunts and adapter to measure the 5500A output. Refer to the 5790A Operator
Manual for operating instructions and connections. See Figure 3-2 for connections, and
see Table 3-5 for shunt information. Table 3-20 shows the test points.
