The accuracy of the power is complex and is determined by using a formula, which combines the errors due to Voltage, Current, and Phase. Power Acc (%) = SqrRt (Vacc^2 + Iacc^2 + Phase Correction^2) Where Phase Correction (%) = 100x(1-Cos(Phase+PhaseAcc)/Cos Phase). The current and voltage terminals must be isolated. A current transformer or clamp meter adaptor must be used if instrument under test has a common negative.
