1 This is determined through a digital computation using the voltage, current, and active power. For distorted
signal input, the value obtained on the KPM1000 may differ from that obtained on other instruments that use
a different method.
2 The measurement accuracy is determined by an expression whose components are the measurement
accuracies of the voltage, current, and active power.
