1. INTRODUCTION
The Multifunction Instrument is a panel mounted 96 x 96mm DIN Quadratic Digital Panel Meter, which measures
important electrical parameters in 3 ph 4 wire / 3 wire / 1ph Network and replaces the multiple analog panel meters.
It measures electrical parameters like AC voltage, Current, Frequency, Power, Energy (Active / Reactive /
Apparent), phase angle, power factor, individual harmonics & many more. The instrument integrates accurate
measurement technology (All Voltages & current measurements are True RMS upto 31st Harmonic) with LCD
display with backlit.
It can be configured & Programmed at site for the following : PT Primary, PT Secondary, CT Primary, CT
Secondary 3 Phase 3W, 3 Phase 4W, 1 Phase 2W system.
The front panel has four push buttons using which the user can scroll through different screens & configure the
product. The front panel also has Impulse red led, flashing at rate proportional to measured power.

The absence of lines indicating the percentage implies that the input current is less than 20% of the CT
Primary value.
Phase Sequence Indication
It indicates the rotation of input phasor vectors :
clockwise/ counter-clockwise.
In case the input is absent or the phase sequence is neither L123 nor L321, the phase sequence indication is not
shown.
2. MEASUREMENT AND ENERGY/COUNTER SCREENS
In normal operation, the user is presented with two simultaneous screens:
1. One of the Measurement screens out of the screens of Table 1.1 / 1.3 / 1.4 .
These screens may be scrolled through one at a time in an incremental order by pressing the respective key. Few
important screens are explained in Section 2.1 to 2.7.
2.One of the Energy/Counter screens out of the screens of Table 1.2.
These screens may be scrolled through one at a time in an incremental order only by pressing the “Enter key” to roll
over again in the same order. Few important screens are explained in Section 2.8 to 2.10
Load Graphics
Load Graphics indicates the input current as the percentage of the CT Primary value. This indication is available for
all measurement screens. For example, consider CT Primary to be set at 5A, then the input current of 2.5 A
indicates 50% as shown below.

RS485 Connection Indication
Digital Input Indication
Digital Output Indication
It indicates that the serial communication between the instrument a nd th e
computer / control / automation system is activated through the RS485 output of the instrument by
glowing continuously. In case the communication is not active, the indication is not shown.
DI1 is configured in Status Mode and is present.
DO1 is energized.
The Digital Input (DI) symbols indicate the following :
These symbols indicate the following :
Tariff Energies Indication
This Instrument comes with 2 tariff based on Digital Input 1 (DI1) for 6
selectable energies each. In the image given here, it indicates that the
instrument is currently displaying the selected energy parameter (System
Import Active Energy) of Tariff 2. Refer TABLE 1.2 for navigation of Tariff
Energies. These energies are available in Energy Parameter Screens on
display.

1. Status of external contacts when DI is configured in Status Mode.
DI1 is configured in Status Mode and is absent.
DI2 is configured for measurement of external pulses.
2. DI is configured for Pulse Mode.
1. Status of the output contacts (Relay).
DO1 is de-energized.
DO1 is configured for Pulse Output.
2. Relay is selected in Pulse Mode.

NOTE : The Display screens of Table 1.4 can be scrolled through V/A Key.

2.1 Current Reversal Screen
This screen is one of the Voltage / Current Parameter Screens and is useful to indicate if current in any phase
is reversed or not. If current in any phase gets reversed, then corresponding phase will be indicated on this
screen.
This screen shows that currents in
L1 and L3 are reversed.
This screen shows that currents
in all three phase are correct.
This screen shows that the meter
has no current input.
2.2 Phase Rotation Error Screen
This screen is one of the Voltage / Current Parameter Screens and shows phase rotation information for the
phase sequence R-Y-B (L1-L2-L3).
This screen indicates that
Phase Sequence is
incorrect.
This screen indicates that
Phase Sequence is correct.
This screen indicates that all
three phases (voltages) are
absent.
User must check this screen in order to get correct readings when meter is connected.
This screen indicates that
either one or two of the
three phases (voltages)
are absent.

2.3 Phase Absent Screen
This screen is one of the Voltage / Current Parameter Screens and is useful to indicate if voltage or current in
any phase is absent. Hence, user will know which voltage or current is missing and take corrective action.
This screen indicates that all three
phases (V & I) are absent.
This screen indicates that V2,
I2 and I3 are absent.
This screen indicates that all
three phases are present i.e.
all inputs are present.

2.5 Load Health Monitor Screen
The Individual Harmonics can be accessed by
pressing the Enter key followed by the Up and
Down keys taking through the 31 harmonics.
Similarly, pressing the “ ” key at the quit screen
takes the user out of the Individual Harmonics Screen.

The Load Health Monitor Menu is one of the System Parameter
Screens and shows the health status of the three phase load. The faults
can be monitored by pressing the Enter Key followed by the Up and
Down keys taking through all the different errors (if any) of the Three
Phase load. Types of Error shown :
1) Phase Fail 2) Unbalanced Voltage
3) Unbalanced Current 4) Phase Reversal
5) Under Frequency 6) Under Voltage
7) Over Current 8) Over Voltage
This screen is one of the Voltage / Current Parameter Screens.

2.7 Timer 1 & Timer 2 Screens
Relay 1 in Timer mode
No. of Cycles = 10
ON Delay = 12 sec
OFF Delay = 5 sec
The screen shows the No. of Cycles, on delay, off delay of the corresponding relay in its timer mode. If the
relay is configured in timer mode, then the timer can be turned ON by long press (about 3sec) of Up key while
present in any of the measurement screens.
Similarly, the Relay can be turned OFF by long press (about 3sec) of Down key while present in any of the
measurement screens.
Relay 1 is not selected in Timer
Configuration.
This screen is shown when relay
is configured as timer by selecting
yes option timer1 can be started.
Timer showing Running when
it is started.
Timer showing Stopped when
