Gain Adjustments

CAU T ION
34405A User's and Service Guide
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 M
procedures.
Adjustments for each function should be performed ONLY in
the order shown.
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.
