3.10 Phase Diagram
Phase diagram graphically represent fundamental voltages, currents and phase angles of the network.
This view is strongly recommended for checking instrument connection before measurement. Note that
most measurement issues arise from wrongly connected instrument (see 4.1 for recommended
measuring practice). On phase diagram screens instrument shows:
 Graphical presentation of voltage and current phase vectors of the measured system,
 Unbalance of the measured system.
