Step 6. Measure the output voltage with the DMM and enter the data.
Front Panel: SCPI Command:
Select the Measured Data field. Enter the data
from the external DMM.
Press Select when done.
Press Next to finish calibration.

Voltage Common Mode Rejection Ratio Calibration
Step 1. For this step, make the connections shown in Cal Setup C.
Connect an external jumper between the +sense and the sense
terminals. Connect a second jumper from the +output to the sense
terminal. For models N6751A and N6752A only, connect a 25 Ω load
resistor across the +output and output terminals.
This procedure is automatic and only takes a few seconds.
Front Panel: SCPI Command:
Select System\Admin\Cal\Misc\CMRR.
Then select Next.

After calibration completes, disconnect all jumpers and resistors.
Current Calibration
High Range Programming and Measurement
The output voltage may go negative at some point during this
procedure on units that have polarity reversal relays (Option 760).
Step 1. Connect a precision shunt resistor to the output. The shunt resistor
should be able to measure at least 120% of the output’s full-scale
current (see Cal Setup B). Connect the Agilent 3458A across the
shunt resistor.
Step 2. Select the full-scale current programming range. The value to
program a range must be the maximum current of the range. This
example selects the 5 A full-scale range of output 1. Full-scale ranges
vary according to model.
Front Panel: SCPI Command:
Select System\Admin\Cal\Curr\Iprog
Then select the High range.
