DESCRIPTION:
LEGEND:
A
:
Key for visualising the three phase system
parameters with its corresponding
LED
. By
pressing again this key, the instrument returns to
reading each individual phase. By keeping the
key pressed for 5 seconds the instrument
reaches the programming mode (
SETUP
). In
SETUP
mode, this key confirms the values set
and by pressing the
B
key simultaneously, it
starts decreasing the value.
B
:
Key for selecting the measured parameters to be
shown at the
C
display. In
SETUP
mode selects
and modifies the value of the parameters to be
set.
A+B
: With the simultaneous pressing of both keys the
instrument reaches the visualisation of the
maximum and average values, which may be
selected with the
B
key. To escape from
maximum and average values visualisation, don
’t
press any key for 8 seconds.
C
:
Three displays for visualising the measures,
subdivided by phase of the parameters indicated
by the LED
D
bar. In case that the
L
LED (
G
) is
glowing, the instruments shows the three phase values of the measures, indicated by the LED
D
bar.
D
:
LED bar for indicating the measures visualised on display
C
.
E
:
Terminals for wiring the voltage measures input and auxiliary supply.
F
:
Terminals for wiring the current measures input and the digital output (when present in the instrument).
G
:
LED for indicating of a three phase value visualisation.
MENU FOR PROGRAMMING THE INSTRUMENT (SETUP)
The instrument’s SETUP menu is reached by pressing the
A
key during 3 seconds. Once in the SETUP menu, it is
possible to select or modify the visualised parameter’s value, by pressing the
B
key.
If no pressing is made on any key during 8 seconds, the instrument escapes from the SETUP menu.
For a correct operation of the multimeters the instrument has to be programmed with the transformation ratio of the
external CT’s.
It will only be possible to reset the energy meters in those instruments fitted with such a characteristic, so as to program
the digital outputs only if the digital outputs is available in the instruments.
The set values are kept without auxiliary supply even.
> 5 seconds,
access to the programming menu (SETUP)
for selecting of a parameter or modifying the
parameter’s value for programming (SELECT)
for confirming the selection or confirming the programmed parameter’s value (ENTER)
