:CAL:ADJ:SOUR -4.025
:CAL:ADJ:SENS -4.025

Set the current source to 0 A output using the
:SOURce:CURRent
command:
:SOURce:CURRent 0.0
•
Measure the voltage across the shunt resistor, and then calculate the current.

Record the calculated current reading in the "Current calibration adjustment data" table in
Remote adjustment (on page 4-4).

Send the source and sense adjustment commands using the calculated current reading for
the parameter. For example:
:CAL:ADJ:SOUR 1e-6
:CAL:ADJ:SENS 1e-6

Set the source to the positive full-range value using the
:SOURce:CURRent
command. For
example, for the 4 A range:
:SOUR:CURR 4

Measure the voltage across the shunt resistor, and then calculate the current.

Record the calculated current reading in the "Current calibration adjustment data" table in
Remote adjustment (on page 4-4).

Send the source and sense commands using the DMM reading as the parameter. For
example:
:CAL:ADJ:SOUR 4.03
:CAL:ADJ:SENS 4.03

Send the
:SOURce:CURRent
command to set the source current to 0 A:
:SOUR:CURR 0.0

Measure the voltage across the shunt resistor, and then calculate the current.

Record the calculated current reading in the "Current calibration adjustment data" table in
Remote adjustment (on page 4-4).

Send the
:CALibration:ADJustment:SOURce
command using the calculated current
value as the command parameter. For example:
:CAL:ADJ:SOUR -1.02e-3
