Section 4: Adjustment
5. Adjust each current range using the procedure summarized in the following table. Do the
following for each range:

Send the :SOURce:CURRent:RANGe command to select the source and sense range to
adjust. For example, for the 1 mA range, the command is:
:SOUR:CURR:RANG 1e-3

Program the source to output the negative full-range value using the :SOURce:CURRent
command. For example:
:SOUR:CURR -1e-3

Record the DMM reading in the "Current calibration adjustment data" table in
adjustment

Use the DMM reading as the parameter for the :CALibration:ADJ:SOURce and
:CALibration:ADJ:SENSe commands. For example, a typical value for the 1 mA range
would be:
:CAL:ADJ:SOUR -1.025e-3
:CAL:ADJ:SENS -1.025e-3

Set the current source to 0 A output using the :SOURce:CURRent 0.0 command.

Record the DMM reading in the "Current calibration adjustment data" table in
adjustment

Send the source and sense adjustment commands using the DMM 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 1 mA range:
:SOUR:CURR 1e-3

Record the DMM reading in the "Current calibration adjustment data" table in
adjustment

Send the source and sense commands using the DMM reading as the parameter. For
example:
:CAL:ADJ:SOUR 1.03e-3
:CAL:ADJ:SENS 1.03e-3

Send the :SOURce:CURRent command to set the source current to 0 A:
:SOURce:CURRent 0.0

Record the DMM reading in the "Current calibration adjustment data" table in
adjustment

Send the :CALibration:ADJ:SOURce command using the DMM reading as the command
parameter. For example:
:CAL:ADJ:SOUR -1.02e-3
