Current Calibration
High Range Programming and Measurement- All Models
Do not connect anything to the Sense terminals
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
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. The following example selects the full-scale range of output 1. For
models N6781A, N6782A, and N6784A, the full-scale 3 A range calibrates both the 3 A and 1 A
ranges.

From the Calibration menu, select Current, High Range Prog and Meas. Then
select Start.
Step 3. Select the first current calibration point and enter the data. This value may be positive or
negative.
Front Panel Menu Reference
Display shows: "Enter P1 measured data" Calculate the shunt current (I=V/R)
and enter the data.
Press Select when done.
Step 4. Select the second current calibration point and enter the data. Wait a minimum of 1 minute for
the output current to stabilize before entering the data.
Front Panel Menu Reference
Wait 1 minute and select Next.
Display shows: "Enter P2 measured data"
Calculate the shunt current (I=V/R) and enter the data.
Press Select when done.
Step 5. Select the third current calibration point for the negative range and enter the data. The value
should be negative.
