Following the adjustment procedure automatically updates the calibration date and
temperature on the device.
Note
You do not need to separately adjust both measurement and output. The
architecture of the NI 4113 ensures that if measurement is accurate, then output is as
well, and vice versa.
Initiating the Adjustment Session
Initiate an external calibration session (a special type of NI-DCPower session) by calling
the niDCPower Initialize External Calibration VI or
niDCPower_InitExtCal
function.
(Optional) You can close the session and commit the new constants to hardware after you
complete each adjustment procedure.

Adjusting Voltage Output and Measurement
Compare a set of voltages measured by the external DMM to both a set of voltage test points
requested by the NI 4113 and to the measured voltages reported by the NI 4113.
