III.7 Display the Phase Angle of Harmonics
When the MAG. is pressed the magnitude of each harmonics is displayed. To
review the phase angle of each harmonic, users can press the PHASE button.
The phase angle shall be displayed next to the %. This phase angle is measured
from the sampled waveform. It may not be 0 for V1. The rest of the phase angle
(V2, V3, I1, I2, and I3) is sampled with respect to V1.
NOTE:
If the waveform is chopped off at the peak or too small in the LCD, press the
RANGE button to select HIGH or LOW range for better display. The range
indicator is a symbol after the unit of RMS value, L or H.
