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 3 A full-scale range of output 1. Full-scale ranges
vary according to model.

Step 3. Select the first current calibration point.
Front Panel: SCPI Command:
Select Next. The information field should indicate:
“Enter P1 measured data”
CAL:LEV P1
*OPC?
Step 4. Calculate the shunt current (I=V/R) and enter the data.
Front Panel:
SCPI Command:
Select the Measured Data field. Enter the data
from the external DMM. Press Select when done.

Step 5. Select the second current calibration point.
Front Panel:
SCPI Command:
Select Next. The information field should
indicate: “Enter P2 measured data”
CAL:LEV P2
*OPC?
Step 6. Calculate the shunt current (I=V/R) and enter the data.
Front Panel:
SCPI Command:
Select the Measured Data field. Enter the data
from the external DMM. Press Select when done.
