Solution
If you need to configure the current limit for your SMU devices, you can use
niDCPower Configure Current Limit VI and
niDCPower Configure Current Limit Range VI.
Current Limit Range VI decides the resolution, while
Current Limit VI defines limit. You will need to ensure that the value set for current limit is within the current limit range.
The bigger range will cause lower accuracy. It's encouraged to set the range just good enough to cover the limit to have better resolution.
