(16) Press SAMPLE to initiate the adjustment. Adjustment is complete when the
BUSY legend goes out.
(17) Apply characterized negative voltage to TI for the range that requires
adjustment. Allow time for TI indication to stabilize.
(18) Repeat technique of (13) through (16) above for negative range gain adjustment point.
(19) Repeat technique of (11) through (16) above for remaining TI ranges that require
adjustment.
(20) Exit CAL menu by pressing [QUIT] 2 times.
(21) Disconnect equipment set-up.

(4) Transfer values obtained in appendix A characterization (table A-3) to table 11
for ranges being adjusted.
(5) Set the TI to the first range requiring adjustment.
(6) Set the calibrator output (displayed) to the zero value for the range being
adjusted (i.e., for 200 V range, set calibrator output to 1 V at 1 kHz).
(7) Press CAL to enter the CALIBRATION menu.
(8) Press [SET] in the CALIBRATION menu.
(9) Enter the true applied value of the calibrator output using TI numeric keypad,
then press [ENTER].
(10) Press SAMPLE to initiate the adjustment. Range zero adjustment is complete
when the BUSY legend goes out and the calibrated measurement is displayed.
