This menu contains user angle and magnitude calibration data for the Phasor Measurement Unit (PMU). This data is
combined with the factory adjustments to shift the phasors for better accuracy.

sources, and they allow the user to calibrate each channel (four voltages and four currents) individually to offset errors
introduced by VTs, CTs, and cabling. The setting values are effectively added to the measured angles. Therefore, enter a
positive correction when the secondary signal lags the true signal and a negative value when the secondary signal leads
the true signal.
