gain calibrations are iterative. Repeating the HF calibration may improve the result.
(11) Set the calibrator output (displayed) to the range gain LF value for the range
being adjusted. (i.e., for 200 V range, set calibrator output to 100 V at 1 kHz).
(12) Press CAL to enter the CALIBRATION menu.
(13) Press [SET] in the CALIBRATION menu.
(14) Enter the true applied value of the calibrator output using TI numeric keypad,
then press [ENTER].
(15) Press SAMPLE to initiate the adjustment. Range gain LF adjustment is
complete when the BUSY legend goes out and the calibrated measurement is displayed.
(16) Set the calibrator output (displayed) to the range gain HF value for the range
being adjusted. (i.e., for 200 V range, set calibrator output to 100 V at 60 kHz).
(17) Press CAL to enter the CALIBRATION menu.
(18) Press [SET] in the CALIBRATION menu.
(19) Enter the true applied value of the calibrator output using TI numeric keypad,
then press [ENTER].
(20) Press SAMPLE to initiate the adjustment. Range gain HF adjustment is
complete when the BUSY legend goes out and the calibrated measurement is displayed.
Range gain HF is iterative; repeating technique (16) through (20) above may improve
result.
(21) Repeat technique of (5) through (20) above for remaining TI ranges requiring adjustment.
(22) When all ranges and modes requiring adjustment are completed, press CAL to
enter the CALIBRATION menu then press [QUIT] twice to exit CALIBRATION menu.
(23) Set calibrator output to STBY.
