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.

1 Connect the calibrator to the front panel HI and LO input
terminals.
2 Select each function and range based on the input voltage
as shown in
3 Make a measurement and observe the result. Compare the
measurement results with the appropriate test limits as
shown in
