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 5- 2 on page 147 ).
2 Press to select the DC voltage function. The DC annunciator will
be illuminated.
3
Select each range in the order shown below. Provide the indicated input
voltage. Compare the measurement results to the appropriate test limits
shown in
Table 5- 3 . (Be certain to allow for appropriate source settling
when using the Fluke 5520A.)
