5.2.1.4 Power Factor
By pressing the
key, the power factor readings page is prompted showing the PF of each phase as
well as the 3-phase reading. Only one page is displayed.
The – sign ahead of the value identifies a capacitive (leading) reading.
5.2.1.5 Energies
By pressing repeatedly the
key, the several energy readings will be displayed consecutively on the
lower right part of the screen.
The energy readings may be recalled at any time irrespective the readings page being displayed.
The energy readings will however disappear upon selection of another readings page but they may be
recalled, at any time, by pressing the
key.
