Harmonics Screen
The Harmonics screen shows the magnitudes of the selected phases of V and I. The scale
is % of nominal.
The slider control displays harmonics of a higher order up to the 50
th
. The V and A
scaling arrows are on the screen in the upper right.
If the power type is delta, V phases are AB, BC, and CA (L1L2, L2L3, L3L1 is available
as a localized European labeling scheme). If the power type is Wye, V phases are AN,
BN, CN, and NG. (N = neutral, G = ground).

Trend Screen
The Trend screen shows live data being recorded as a strip chart display of the selected
phases of voltage or current. This moment in time is visible on the right side of the graph.
The traces fill the screen in 10 minutes, and continue FIFO (first-in, first-out). This
feature is intended to paint a picture of the short-term stability of the power system. The
V and A scaling arrows on the upper right work like the scaling arrows on the PHASOR
screen.
