AC current verification test
1 Connect the calibrator to the front panel I (red) and LO (black) input terminals
(see Figure 1-6, “Test setup for DC current and AC current gain verification,”
on page 31).
2 Press [ ] to select the AC current function. The AC annunciator will turn on
according to your selection.
3 Select each range in the order shown below. Provide the indicated input
current and frequency. Compare the measurement results to the appropriate
test limits in Table 1-6 . (Be certain to allow for appropriate source settling
when using the Fluke 5520A.)
2-wire resistance gain verification test
1 Connect the calibrator to the front panel (red) and LO (black) input
terminals (see Figure 1-4, “Test setup for 2-wire resistance gain verification,”
on page 30).
2 Press [ ] to select the resistance function.
3 Select each range in the order shown below. Provide the indicated input
resistance. Compare the measurement results to the appropriate test limits in
Table 1-7 (be certain to allow for appropriate source settling when using the
Fluke 5520A).
