DMM7510-905-01 Rev. A / April 2015

DC voltage adjustment steps 3 and 4: +10 V and -10 V

To prepare to run DC adjustment steps 3, 4, and 5:

1. Connect a cable between the calibrator and the Model DMM7510, as shown in the figure below.

2. Allow the instrument and cable to settle for 5 minutes.

To run DC adjustment step 3:

1. Source

+10 V

and allow the calibrator to properly settle.

2. Ensure that the calibrator output is enabled.

3. Send the following command.

Ensure

cal.adjust.dc(3, 10.0)

. The 10 V value may be ±10 % depending on the actual output

of the calibrator.

cal.adjust.dc(3, 10.0) -- 10V Require HI and LO Ft terminals.

To run DC adjustment step 4:

1. Source

-10 V

and allow the calibrator to properly settle.

2. Ensure that the calibrator output is enabled.

3. Send the following command.

Ensure

cal.adjust.dc(4, -10.0)

uses the actual output value of the calibrator.

cal.adjust.dc(4, -10.0) -- '-10V Require HI /LO Ft terminals.
