After all test points are measured for a range, call the niDCPower Cal Adjust Output Resistance
VI or the
niDCPower_CalAdjustOutputResistance
function to calculate updated
calibration coefficients. Refer to Table 26 for parameters specific to adjustment applications for
this VI. Refer to the
NI DC Power Supplies and SMUs Help
for more information about
programming references common to VIs within the NI-DCPower API.

After the new coefficients are calculated, commit them to the hardware using the process
described in the
section.
