4-wire resistance gain verification test
1 Connect the calibrator to the front panel (red) and LO (black) input
terminals and (red) and (black) output terminals (see Figure 1-5, “Test
setup for 4-wire resistance gain verification,” on page 31).
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 1-8 (be certain to allow for appropriate source settling when using the
Fluke 5520A).

NOTE
For the 1 Ω and 10 Ω range, please perform calibrator zeroing before testing the
resistance values of the device-under-test (DUT) to ensure that the 5520A is
maintained with a zero cal. every 12 hours ± 1
