Press Shift Cal, scroll to CAL DVM, and press Enter.
CAL:DVM
53.
Press Shift Cal, scroll to CAL LEV, and press Enter to select the first
calibration point.
CAL:LEV P1
54.
Press Shift Cal, scroll to CAL DATA, press Enter Number, and enter
the voltage value displayed on the external DMM. Numbers entered from
the external DMM should have an accuracy and resolution of 0.1 mV or
better. Press Enter.
CAL:DATA 0.00
55. Reverse the output 1 connections. Move the - lead to the + DVM connector
pin, and move the + lead to the - DVM connector pin.

Press Shift Cal, scroll to CAL LEV, use Æ to scroll to P2 (the second
calibration point), and press Enter.
CAL:LEV P2
57.
Press Shift Cal, scroll to CAL DATA, press Enter Number, and enter
the second voltage value displayed on the external DMM. Numbers entered
from the external DMM should have an accuracy and resolution of 0.1 mV
or better.
Because this second value is negative, you must place a minus sign in front
of the value. Pressing the Enter Number key the second time enters the
minus sign. Then press Enter.
CAL:DATA −0.00
Saving the Calibration Constants
WARNING: Storing calibration constants overwrites the existing ones in non-volatile memory. If you
are not sure you want to permanently store the new constants, omit this step. The dc
source calibration will then remain unchanged.
