MULTI FUNCTION METER
1. General Features
The Meter is designed with latest state of art technology. It offers
high accuracy, reliability and also real value for money. This next
generation micro controller based instruments monitors over 25 vital
parameters and does not require any external Transducers. This
instrument is most suitable for measuring all electrical parameters in 3
phase industrial applications. It replaces several meters like Voltmeters,
Ammeters, Wattmeters, Frequency meter, kVA meter, kVAr meter, pf meter
and selector switches for the above in an electrical panel.
The measured informations are shown on a 2 row 16 character
LCD display with backlit. Four keys are provided on the front panel of the
meter to access these information easily and quickly. The front panel is
provided with antiglare feature for improved readability.
The measurement parameters include 3 phase voltage, 3 phase
current, kVA, kW, kVAr, PF, Frequency, kWh (or) kVAh. All voltage,
Current, Power and energy readings are true R.M.S including
harmonics. The power and energy measurement is done for the full four
quadrants. The energy reading is provided with reverse lock, showing
only the imported energy consumed by the consumer. The meter
computes and updates the parameters in every 2 seconds.
The meter is also provided with a optional RS 485 optically
isolated communication port supporting MOD BUS RTU protocol. The
port is very useful in networking the meters in multidrop communication
and to collect datas in a centralised control room using any standard
SCADA Software package like cimplicity, intellution, wonderware & citech
etc.
(Note : For Every change of LT HT or 1A 5A or 3 Wire 4
Wire the instrument should be switched OFF and then made ON.)

2. Installation
2.1. Mounting
The meter is housed in a compact ABS plastic enclosure of
dimension 96(H) x 96(W) x 45(D)mm. The meter is suitable for panel
mounting and has reliable mounting clamps to hold the meter to the
panel.
The panel cut out for fixing the meter is a 92 x 92 mm. The
depth behind the panel is 45 mm. Always provide extra space for the
connectors and wiring. The panel cut out should be punched with
proper tool and should be free from burrs. Insert the meter through
panel cutout from front and fix the mounting clamps provided with the
meter on each side. Tighten the fixing clamps with limit amount of force
so as to hold the meter in position.
2.2. Wiring
2.2.1 Selection of PT & CT
The measurement of voltage and current is done using the PT
voltage and CT current inputs. So the accuracy of measurement is
determined by the accuracy and phase shift produced by the PT’s and
CT’s so it is recommended to use PT’s and CT’s of instrument class
0.5 or better.
Also the PT’s and CT’s should have adequate VA rating to
support the burden on the secondary side of them. The primary rating
of the CT has to be selected such that the load variation lies between
the dynamic range of the CT. (30% to 80% of the primary current).

2.2.2 Voltage signal connections
The Meter directly accepts voltages upto 415VAC R.M.S line to
line (240VAC R.M.S line to neutral) with 10% over load capacity in
case of LT meters and 110VAC R.M.S line to line (63.5 VAC R.M.S line
to Neutral) with 10% over load capacity in case of HT meters. The
primary of the PT is field programmable upto 330 kV.
There are four voltage input terminals marked as R, Y, B & N.
The three phase input voltage should be connected to those
terminals.
Meter voltage input burden : 0.25VA per phase
2.2.3 Current signal connections
The Meter current inputs can accept both 5A AC or 1A AC
R.M.S (selectable) for connecting external CT’s. The CT Primary &
Secondary value is field programmable. In both the cases, the current
inputs has over load capability of 120%.
There are three pairs of terminals marked as IR (M,L) IY (M,L)
and IB (M,L) for the connection of external CT’s. For proper
measurements, the polarity of the CT’s must be connected properly.
The CT wiring must be properly done by deenergising the CT
secondary by shorting it through a shorting block. The primary current
of CT is field programmable upto 10000A.
Meter Current input burden : 0.25VA per phase

3.3) Auxiliary power supply connections
The Meter derives power from auxiliary power supply terminals
which is seperatly provided in the meter. SMPS circuit is used to power
up the meter so it can work from th range of 90 - 270V AC/DC. The
auxiliary supply should be connected to proper specified voltage.
Burden on Auxiliary supply terminals : 4VA
3.4) Cross checking the wiring
Three phase voltage wiring and current wiring are to be properly
done for correct measurements. Any wrong connections done either
during installation or during rewiring can produce wrong measurement of
electrical parameters. These incorrect wirings are difficult to detect since
they produce wrong readings close to the expected readings.
The Meter has a built in program to identify the reverse sequences
in PTas well as CT wiring. A seperate diagnostic display page is provided
to view the PT, CT Connections. IT can be selected by pressing the Shift
Key repeatedly.
If the PT & CT wiring are done correctly. The diagnostic page as
shows as
Otherwise the phase in which voltage connections or current
connections are wrongly connected is displayed.
While checking the wiring through the diagnostic page, make sure
the load current is 10% above the full scale current and also the load is
in import mode.
Note :(PT shows “RYB” when sequence connected is correct (RYB, YBR & BRY) or
else shows “RBY’, if sequence connected is incorrect (RBY, YRB & BYR). CT shows
reversal, when CT not synchronised with PT or wiring are Interchanged/Reversed or

7. Communication Port Details
The Meter is provided with a optically Isolated RS 485
communication Port, which is an optional Feature and has to be
specified at the time of ordering. The communication protocol used is
MODBUS - RTU or MODBUS-ASCII (to be specified while ordering). Using
the communication Port, the meters can be connected in multi drop
network and data can be collected in a centralised control room using
any standard SCADA Software.
The communication between the PC and the instrument would
be in Master slave mode. P.C acts as a master and sends a command
message (query) containing the slave Id, function code and address of
the information required. The command is received by all the slaves.
The slave whose address is matching with that of the command address
would respond with the requested data.
The communication settings are,
Protocol : MODBUS RTU
Data bit : 8
Data Type : UINT
Baud rate : 9600
Parity : None
Stop bit : 1
Starting Address : 40001
Communicating mode : Half Duplex
The above configuration are to be done in any standard scada
package for collecting the data.
The instrument is provided with screwable 2 pin phoenix
connector for connecting the communication cable at the rear side.
Note : kWh or kVAh are shown in the same address which ever is
selected in program mode

7.1 Communication connection diagram
When connecting the meters in multidrop communication
network, the following methods are to be adopted for trouble free
communication.
1. Loop Topology
In this method, the communication continous to work even if
there is a breakage in any one of the Loop. Termination resistors are
not required.
2. Straight line Topology
In this method termination resistor RT (60 -100 ) of value
equal to characteristic Impedance of the cable used may be required
to avoid reflection loses.
It is recommended to use proper & suitable communication cable
for trouble free communication.
