Step 7. Select the third voltage calibration point for the negative range.
Front Panel:
The third calibration point is automatically
selected. "Enter P3 measured data" should be
displayed.
Step 8. Calculate the shunt current (I=V/R) and enter the data. The value should
be negative.
Front Panel:
Enter the calculated value into the data field
and then select Next. When calibration is
complete, select Close
Low Range Current Programming - Models N6781A, N6782A,
N6784A
Step 1. Connect only the current measurement terminals of the Keysight 3458A
to the output terminals (see Cal Setup D without the resistor).
Step 2. Select the low-current programming range. The value to program a range
must be the maximum current of the range. Models N6781A and N6782A
have 300 mA range. Model N6784A has a 100 mA and a 10 mA range. This
example selects the 300 mA programming range of output 1. For model
N6784A, select the 100 mA programming range.
Front Panel:
From the Calibration menu, select Current,
Low Range Programming. Then select
Start.
Step 3. Select the first current calibration point.
Front Panel:
The first calibration point is automatically
selected. "Enter P1 measured data" should be
displayed.
Step 4. Measure the current with the Keysight 3458A and enter the value. This
value may be positive or negative.
Front Panel:
Enter the value from the external DMM into
the data field and then select Next.
Step 5. Select the second current calibration point.
