Gain Verification

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 HI and LO input terminals.
2 Select each function and range in the order shown below. Provide the
input shown in the table below.
3 Make a measurement and observe the result. Compare measurement
results to the appropriate test limits shown in the table. (Be certain to
allow for appropriate source settling when using the Fluke 5520A.)
