Gain Adjustment Considerations
• The zero 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 2 hours
before performing the adjustments.
• Consider the thermal effects as you are connecting test leads to the
calibrator and multimeter. It is recommended to wait one minute before
starting the calibration after connecting the test leads.
Never turn off the instrument during a Gain Adjustment. This may cause calibration
memory for the present function to be lost.
