INTRODUCTION TO WM30

DESCRIPTION OF THE DISPLAY

Graphic bar which displays the active and the apparent power drained with relation to the installed

power.

Indications of inductive phase displacement L, -L, or capacitive phase displacement C, -C.

Indication of the measurement phase-neutral L1 or phase-phase L12.

Indication of the measurement phase-neutral L2 or phase-phase L23 or of the asymmetry phase-

phase VLL.

Indication of the measurement phase-neutral L3 or phase-phase L31 or of the asymmetry phase-

neutral VLn.

Indication of the engineering unit and of the multiplier: k, M, V, W, A, var (VAr), PF (Pf), Hz, An.

ALR: the alarm display function is active. PROG: the programming function is active.

Area dedicated to the visualization of counters, text messages, date and time (format:

dd.mm.yy/hh:mm). Energy counters (see table on the following screen).  

Indication of: dmd, THD% or Max.

Indicates that all the instant values displayed are system values.

Phase sequence error alarm.

Instrument programming enabled.

Instrument programming disabled.

Data transmission (TX) and reception (RX), via network communication, in progress.

Notes: the display is backlighted with lighting time programmable from 0 minutes (always on) to 255
