AC voltage verification test
1 Connect the calibrator to the front panel V (red) and LO (black) input terminals
(see Figure 1-2, “Test setup for DC voltage and AC voltage gain verification,”
on page 28).
2 Press [] to select the AC voltage function. The AC annunciator will turn on
according to your selection.
3 Select each range in the order shown below. Provide the indicated input
voltage and frequency. Compare the measurement results to the appropriate
test limits in Table 1-5. (Be certain to allow for appropriate source settling
when using the Fluke 5520A.)
