CHAPTER 1 ─INTRODUCTION
1.1 About the ElNet Multimeter
Large consumers of electricity e.g. factories, hotels, hospitals,
municipalities, need to know the history of their consumption and
the quality of the power supply. Details such as Voltage, Current,
Power Factor, Hertz, Neutral Current, Energy Demands and all
electricity related events are recorded in the ElNet Energy &
Power Multimeter.
An additional feature of the Multimeter is the ability to measure
Harmonics. Part of the Electricity Supply Authority’s bill reflects
poor or good Harmonics in the consumer’s system, therefore it is
in his interest to monitor Harmonics and try to improve it.
These are all recorded on a continual basis and can be recalled
and shown on the front panel display of the instrument with a few
simple key-strokes any time the user wishes.
The ElNet Energy & Power Multimeter is a compact, multi
functional, three-phase Multimeter simple to install and is
especially designed to integrate into Building Management
Systems. It requires no special mounting and is ideally suited for
mounting on the front face of any standard electrical panel.
The Configuration and Setup is menu driven, with password
protection.
Communication with external devices is simple and is based on
standard known technology.
The ElNet Energy & Power Multimeter boasts a new
innovative built in “Flash Memory”, which pioneers a new
frontier into electrical measurement. It has a 1 MB of FLASH

6
MEMORY with a capacity of recording up to 2 years of power
malfunctions and interruptions.
Readings, graphs, tables & history are shown on the graphic
display of the ElNet Energy & Power Multimeter . This
display is a state of the art screen with a resolution of 160X128.
Each ElNet Energy & Power Multimeter is carefully and
meticulously manufactured using quality components and the
latest production methods. Before leaving the factory each
ElNet Energy & Power Multimeter is calibrated and sent to
the customer accompanied by the test certificate and Certificate of
Compliance (C.O.C).

2.4 Rear Panel Connections
Please re-read section 1.3 for safety instructions.
To connect the Rear Panel
All Connections, except those to the CT core of the ElNet
Energy & Power Multimeter are made via terminal connector
plugs (Voltage input, Power Supply, Communication etc.).
Max. recommended tightening torque for the connector screws is
0.5 Nm.
The CT cores of the ElNet Energy & Power Multimeter are
located externally on the rear of the instrument and the lead from
the leg of the external Current Transformer must pass through in
the correct direction.
Insert the lead from side “L” of the Current Transformers of Line
1through the bottom of the CT core I1A, (top left looking from
back), of the ElNet Energy & Power Multimeter.
NOTE!
Ensure all the connections to the leads of the current
transformer wiring are secure and there is no mechanical
strain on the wire. The cross section of the leads to the
current transformer must be compatible to the power of the
current transformer. We recommend a power transformer
with at least 3VA and the length of the wiring of the
transformer no longer than 3m.

19
WARNING
Repeat the procedure for Line 2 and Line 3.
•Ensure the leads from leg “L” of the Current
Transformer on Line 1 pass through the bottom of
CT core I1A.
•Ensure the other end of the lead emerging from the
top of C T core I1A is connected to leg “K” of the
Current Transformer on Line 1
WARNING!
Never allow an open circuit between the two Current
Transformers.

20
Connect the rest of the connections to the ElNet Energy &
Power Multimeter by means of terminal connector plugs.
The Rear Panel (See Figure 2.4.)has all connections printed and
is simple to follow. (See table 2-1 for connections)
