Gain adjustments
The instrument calculates and stores gain corrections for each input value.
The gain constant is computed from the calibration value entered for the
calibration command and from measurements made automatically during
the adjustment procedure.
Most measuring functions and ranges have gain adjustment procedures.
The 100 MΩ range does not have gain calibration procedures.
Adjustments for each function should be performed ONLY in the order
shown.
Gain adjustment considerations
• The zero offset adjustment procedure must have been recently
performed prior to beginning any gain adjustment procedures.
• Be sure to allow the instrument to warm up and stabilize for 120
minutes before performing the adjustments.
• Consider the thermal effects as you are connecting test leads to the
calibrator and instrument. It is recommended to wait 1 minute before
starting the calibration after connecting the test leads.
Never turn off the instrument during a gain adjustment. This may
cause the calibration memory for the present function to be lost.
