b)
Input the NI 4141 measurements as the
reported outputs
.
c)
Input the specified level range as the
range
.
Connecting and Configuring Equipment to Adjust
Residual Offset Voltage
1.
Make the necessary connections for this procedure, as shown in the following figure:

NI-DCPower Device
Sense LO
Sense HI
HI
LO
2.
Set the
niDCPower Output Function
property or
NIDCPOWER_OUTPUT_FUNCTION
attribute to DC Voltage for the NI 4141.
Adjusting Residual Voltage Offset
Eliminate residual offset voltage at 0 V by configuring and calling the niDCPower Cal Adjust
Residual Voltage Offset VI or
niDCPower_CalAdjustResidualVoltageOffset
function.
Adjusting Residual Current Offset
1.
Disconnect all equipment from the output of the NI 4141.
2.
Eliminate offset current at 0 A by configuring and calling the niDCPower Cal Adjust
Residual Current Offset VI or
niDCPower_CalAdjustResidualCurrentOffset
function.
Closing the Adjustment Session
Close the session and commit the new constants to hardware by calling the niDCPower Close
External Calibration VI or
niDCPower_CloseExtCal
function and specifying Commit as
the
calibration close action
.
