Voltage and Current Phasor
Overview
Phasor display
The phasor screen displays a graph that indicates the phase relations between the
voltage and current based upon the angles of the fundamentals, as determined by
Fourier analysis.
Phasor screen shows eight phasors autoscaled with zero degrees to the right (normally
channel A voltage) for clockwise rotation and with synchronized channels. Users are
allowed to display up to four channels at any one time for either volts or amps, or a
single channel for both volts and amps, depending on the phases being monitored.
A touch screen Demo button presents an animated phasor demo rotation for resistive,
capacitive and inductive loads.
