FOR EXAMPLE:

Once View Graph is selected,

coordinates for V RMS

Imbalance event are displayed on

screen.

NOTE: Imbalance is the rms

deviation calculation per channel

if the instrument is in Standard

PQ Mode. It will display the

ANSI definition of unbalance for

channels A, B and C if the

selected monitoring mode is other

than EN50160. When monitoring

under EN50160 mode, Imbalance

will be a simple value as per IEC

definition, defined as the sum of

negative sequencing components

divided by the sum of positive

sequencing components (similar

to meter readings under Meter

Mode).

• Press the Magnify button to

use the zoom features and to

view plot coordinates in detail.

• Press Param to show the

trigger parameter and channel/s

displayed on screen.

• Press Exit to return to the PQ

Status screen.
