Verifying Current Programming Accuracy
To verify current programming accuracy, compare a set of requested current test points to
measurements of the actual current at the output by the DMM. Connect an NI APS-4100
auxiliary power supply for this verification procedure. Refer to Figure 3 and Figure 4 for the
necessary connections.
