For single phase measurements, use current input A (L1) and the voltage inputs Ground,
N(eutral), and phase A (L1).
A (L1) is the reference phase for all measurements.
Before making any measurements, set the Analyzer up for the line voltage, frequency,
and wiring configuration of the power system you want to measure. This is explained in
Chapter 24, General Settings.
Scope Waveform and Phasor display are useful to check if voltage leads and current
clamps are connected correctly. In the vector diagram the phase voltages and currents A
(L1), B (L2), and C (L3) should appear in sequence when observing them in clockwise
direction as shown in the example in Figure 6-3.
