10 µA Measurement Range - Models N6781A, N6782A, N6784A
Step 1. Connect the Keysight 3458A in series with a 1 MΩ resistor to the output (see
Required and Cal Setup
autoranging). The remote command to do this is "DCI 100e-6".
Step 2. Select the 10 μA measurement range of output 1.

From the Calibration menu, select Current, 10 μA Measurement Range. Then
select Start.
Step 3. Select the first current calibration point and enter the data.
Front Panel Menu Reference
Display shows: "Enter P1 measured data" Measure the current with the Keysight
3458A and enter the data.
Press Select when done.
Step 4. Select the second current calibration point for the negative range and enter the data. The
value should be negative.

Current Limit - All Models
This procedure calibrates the POSITVE current limit for Models N6781A, N6782A,
and N6784A. It calibrates the NEGATIVE current limit for Models N6785A and
N6786A.
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 rated full-scale current (see
across the shunt resistor.
Step 2. Select the 3 A current limit of output 1 for models N6781A, N6782A, and N6784A. Select the -
8A current limit of output 1 for models N6785A and N6786A.
