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).
1.2 How to use this manual
We at CONTROL APPLICATIONS Ltd, envisage this manual to
be used by three types of people, i.e. the Installation Technician,
the Senior Electrical Engineer and the end User. For this reason
this manual is divided into chapters for ease of reference by each
of these different people. There could be a situation where two of
the abovementioned tasks can be combined, or in a rare instance
one person could handle all three tasks.
CHAPTER 1, Introduction, describes the ElNet Energy &
Power Multimeter , its potential users, the readings it can
provide and some of its features in brief.
CHAPTER 2, Installation, provides detailed instructions for
unpacking, mechanical mounting, and electrical wiring up
instructions for the Installation Technician.

7
CHAPTER 3, Using the ElNet Energy & Power
Multimeter, describes in detail front Panel, the functions of the
control buttons, and the Lock Utility.
CHAPTER 4, Parameter Configuration & Settings explains in
detail the minimum parameters settings needed by the Senior
Electrical Engineer to set up and configure the ElNet Energy
& Power Multimeter.
CHAPTER 5, Front Panel Displays, is an easy to follow step-by-
step guide to obtain readings, graphs, tables and histories for the
User.
CHAPTER 6, Alarm reports gives details about how to program
the Alarms in the ElNet Energy & Power Multimeter.
CHAPTER 7, Demand reports is an easy to follow step-by-step
guide to obtain the Demand reports up to 2 years.
CHAPTER 8, Data Logging is an easy to follow step-by-step
guide to obtain all the stored peaks of current, voltage, energy,
power factor etc. up to 2 years of data logging.
CHAPTER 9, Communications gives details about the
Communication capabilities of the ElNet Energy & Power
Multimeter, and how to Set Up.
CHAPTER 10, Specifications, is a detailed list of specifications of
the ElNet Energy & Power Multimeter.
APPENDIX A, Installation & Configuration Check List, provides
a Check List to insure no important steps will be missed during
the initial set up.

1.3 Safety Information
The purpose of this manual is to help you. Please read the
instructions carefully before performing any installation and note
any precautions.
•Ensure that all incoming AC power and other
power sources are turned off before
performing any work on the ElNet
Energy & Power Multimeter . Failure to
do so may result in serious or even fatal
injury and/or equipment damage.
•If the ElNet Energy & Power
Multimeter is damaged in any way do NOT
connect it to any power source.
•To prevent a potential fire or shock hazard,
never expose the ElNet Energy & Power
Multimeter to rain or moisture.
•Keep the surrounding area free of dirt and
clutter especially metal objects. Good
housekeeping pays.
•Inspect the cables periodically for cracks,
kinks or any other signs of wear
•Keep children away.
•Do not pull the cords.
WARNING

9
•Users should stay alert and not approach the
rear of the ElNet Energy & Power
Multimeter while tired or under the
influence of alcohol, medicines or any other
chemical substance that would tend to make a
person drowsy.
•Do not wear loose clothing or dangling
jewelry.
•Above all use common sense at all times.
