Figure 1-4. Permissible Combinations of AC Voltage and AC Current for Power and Dual Output
Calculate the Uncertainty Specifications of Power and Dual Output Settings
Overall uncertainty for power output in watts (or VARs) is based on the root sum square (rss) of the individual
uncertainties in percent for the selected voltage, current, and, if AC power, the phase parameters:

Because there are an infinite number of combinations, you must calculate the actual ac power uncertainty for your
selected parameters. The results of this method of calculation are shown in the subsequent example. These examples are
at various selected calibrator settings (with 1-year specifications):
