Gain verification test
This test checks the full-scale reading accuracy of the instrument. Verification
checks are performed only for those functions and ranges with unique gain
calibration constants.
DC voltage gain 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 DC voltage function. The DC annunciator will turn on
according to your selection.
3 Select each range in the order shown below. Provide the indicated input
voltage. Compare the measurement results to the appropriate test limits in
Table 1-3. (Be certain to allow for appropriate source settling when using the
Fluke 5520A.)
