Dear customer, than you for selecting the VIP
Multimeter for measurements of voltage, current,
power and power factor.
1. Mechanical Installation
1.1 Please choose the proper place for installation
in panel and prepare a square hole according to
exhibit below.
Space in the electrical panel
Comment: Please do not install the VIP
Multimeter close to electrical bars.
Please lea e enough space for approaching the
de ice from its back side for pro iding
technical support .
Width
90 mm
Height
90 mm

1.2 Please insert the VIP Multimeter into the
suitable space which is to be prepared in
ad ance. Make sure that the de ice is inserted
in the right direction. The de ice has a
plastic knob which adjusts itself for
installation in electrical panels. The
thickness of the panel door should be less
than 4 mm.
1.3 Ensure the VIP Multimeter is firmly in
place.

4. Current transformer ratio settings
4.1 Press the "Enter" button for about 6 seconds.
4.2 The enter password screen will appear:
"COD".
4.3 Use "↑" button to change the code to "1" and
press Enter.
4.4 The current transformer set screen will appear.
4.5 The headline "SET" will be displayed on
the screen, on the second line the secondary alue
of current transformer (5A), the third line allows
to define the alue of the primary current
transformers with the "↑ ↓" buttons. At the end
press Enter.

5. Measured values display
5.1 Use the "↑ ↓" buttons to browse among all
the display screens including three-phase display
of oltage, current, power, frequency, power
factor and integrated screens of oltage, current
and power factor for each phase.
. Peaks display
6.1 Pressing the Hi/Lo button (each press replaces
screens circularly), enables you to browse among
the screens specifying the peak of oltage and
current that were e er measured for each phase.
The first screens display the highest alues
measured of oltage and current (Hi); the next
screens display the lowest alues measured of
oltage and current (Lo) and then respecti ely
high and low frequency and power factor for each
phase.

7. Indication led
7.1 The indication led easily enables to
identify whether there is oltage in phases L1,
L2, L3. In case there is oltage in phases
connections the led will be turned on (50 VAC at
least).

8. Communication Settings (for
devices with communication port):
In order to connect the ElNet VIP Power
Multimeter to a PC or other de ice, for
successful communications, both communication
Setup parameters must match; i.e. the PC port and
the configuration settings of the Power meter,
Address, Baud Rate, Parity must match.
8.1 Communication Address:
Each Power meter in a communication system
must ha e its own unique address. ElNet VIP
works on MODBUS protocol, so the a ailable
addresses are - from ‘1’ to ‘247’.
8.2 Baud Rate:
The Baud Rate is the communication speed in Bits
per second (BPS) for communication between
ElNet VIP with the PC or other de ice. The better
the communication line quality, the faster the
communications may be (higher Baud Rate alue).
If the communication line is routed through a
“noisy” en ironment, it may be necessary to
decrease the Baud Rate.
8.3 Available Baud Rates for the ElNet VIP
Are: 300; 600; 1200; 2400; 9600; 19200 bps.
8.4 Parity:

The parity can be defined as ODD, NONE or
EVEN.
8.5 Set up Communication
8.5.1 Press the "Enter" button for about 6
seconds until the insert password screen will
appear.
8.5.2 Use the "↑" to change the password
(COD) to "2" and press "Enter".
8.5.3 The message "SET" will blink on
the screen. On the second line, you will
find the functions that require setting.
Figure 6.1 – Communications settings

8.5.4 Use the "↑ ↓" buttons to chose the
required communication feature and press "Enter":
• Address "Adr" – can be changed by
using "↑ ↓" buttons from 1 to 255, when
finished press "Enter".
• Baud "bud" – use the "↑ ↓" buttons to
choose 300,600,1200,2400,4800,9600,19200.
• Parity "PAr" - use the "↑ ↓" buttons to
choose from:
O81 - ODD, 8 data bit, 1 Stop bit.
E81 - EVEN, 8 data bit, 1 Stop bit.
n81 - NONE, 8 data bit, 1 Stop bit.

9. No volt relay
9.1 General:
When the oltage is proper (abo e 50VAC,
adjustable) and the phases' order is proper the
indication relay is closed, as appears at the wiring
diagram. The maximum current that is possible to
transfer through this relay is 150ma which is
enough to operate a regular control relay.
9.2 No volt alarm setting:
9.2. 1 In order to set the minimum oltage
alue for the no olt relay press the "Enter"
button for about 6 seconds.
9.2.2 Use the "↑ ↓" buttons to change the
password to "code 21" and press "Enter".
9.2.3 "SET AL" will appear and it would be
possible to set the min. oltage ratio by
using the "↑ ↓". After setting this alue
sa e it by pressing the "Enter" button.

9.2 Phase order alarm:
9.3.1 In order to turn ON/OFF the phase order
relay, press the "Enter" button for about 6
seconds.
9.3.2 Use the "↑ ↓" buttons to "code 31" and
press Enter.
9.3.3 The phase order screen will appear
and it would enable you to select YES/NO
(equi alent to ON/OFF). After setting the
desirable option sa e it by pressing the
"Enter"
button.
