MEASURES VISUALIZATION
The instrument is divided in two distinct section:
the first is composed by three displays (
F
), by
A
and
B
keys and
by LED bar
D
; the second (in the low part) is composed by
G
display, by
C
key and by LED bar
E
.
The two sections are to consider as two different instruments in
a only one box, in fact it’s possible to act in a zone without to
modify the visualization in the other (peak value and energy
counters visualization excluded).

Visualization section 1
The three measures of phases (on L1, L2 and L3), of the
parameter indicated from the led
D
on, appears on
F
display.
For the measure of the phase to phase voltages (V
L-L
), the three measures are V
L1-L2
, V
L2-L3
, V
L3-L1
.
It’s necessary to press the
B
button to select the parameter that can be displayed and indicated from
D
LED.
Press
A
button to see on
F
display the three phase value (the average of the single phase of voltage, current, power
factor and the sum of single phase for the power) of the parameter selected,: the led inside the
A
key is on.
To press another time the same key the visualization come back at the phase values.
The unit of measurement can be expressed in kilo or Mega, in the this case the relative LED is on.
A sign – on the first digit indicates the visualization of the capacitive power factor (example the reading -.95
indicates a power factor of 0.95 capacitive).
Note: If in the Setup the single phase mode (1PH
L1) is set, all the measures appear on the L1 display.
Visualization section 2
At the same way of the section 1, press the
C
button
to select the parameter that can be displayed and
indicated from
E
LED. The voltage values are of the
three phase system, the frequency is of the L1
channel. See table for detailed info.
Visualization energy and hours counters
With the
C
key it’s possible to visualize on
F
display
the active, reactive and apparent energy counters. One
segment of the right digit of the
G
display, in
correspondence of the
kWh
and
KVArh
on the front
panel, turn on, to indicate the visualization of the
active and reactive energy counters. The led
VA
and
the segment of the right digit of the
G
display, in
correspondence of
…h
on the front panel, turn on, to
indicate the visualization of the apparent energy
counter. To complete the visualization the led
k
over the
F
display could be on.
This is the visualization if NORMAL is the set in SET
EN item of
the setup. Instead if the setting is TOT PAR
on the
F
display will be visualized alternatively the
partial and the total active, reactive and apparent
energy counters; the first digit of the
G
display
indicates the type of the counter: P for the partial (the
user could be reset it) and T for the total (it’s no
possible to reset it). If the setting is TB1 TB2 on F
display will be visualized alternatively of the counters of
the band 1 (B1 on the first two digit of
G
display) and
of the band 2 (B2 on the first two digit of
G
display).
The right digit of
G
display, in correspondence of the
…h
,
turn on, when the visualization of hours counters is active.
The reading of the counters use the 9 digits (maximum
reading 9999999.9) of the
F
display: the measure is displayed
in the way that the L1 display will indicate the first 3 digits, the
display L2 the seconds 3 digits and the L3 display the last 3.
For example if: L1=000, L2=028, L3=53.2 the reading is
2853.2 kWh.
