6 When the calibration has been completed for the selected range, the
status box shows DONE, and the value in the Calibration Range box
flashes.
7 Verify the Ohms gain adjustments using the “Ohms gain verification
test” on page 14.

[1] Configure to 2-wire compensation mode for calibrator for better accuracy. Cal item 0 Ω only calibrated once during ohms
gain adjustment procedure. You need to re-calibrate once you exit calibration mode.
[2] Remove test lead for 2-wire calibration.
[3] Do not remove kelvin 4-wire connection at the other end of the test leads (for DUT measurement) for 4-W resistance
calibration.
NOTE
Before initiating any gain adjustment procedures, perform the zero adjustment at any range
first.
