In this discussion, metrology results are shown. Current transformers have been used, however, the code supports shunt resistors as well. Figure 6-6 shows the results for current that is varied from 50 mA to 100 A exhibiting a 2000:1 dynamic range. Table 6-1 shows the values for the error at room temperature.
