2 Use the DMM to measure the dc voltage at the front-panel Output
connector for each setup in the following table.
* Constants are stored after completing this setup.
3 Using the numeric keypad or knob, adjust the displayed voltage at each
setup to match the measured voltage. Select ENTER VALUE. (Entered
values are rounded to the nearest 100 µV.)
4 After performing setup 33:
a. If your calibration procedures require you to verify the adjustment
just made, exit the calibration menu and perform “AC Amplitude (high-
impedance) Verification”, on page 61.
b. If you are making all the adjustments and then verifying the instrument’s
performance, continue with the next procedure in this chapter.
