1. Introduction
This instrument is a panel mounted 96 x 96mm DIN Quadratic Digital metering system for the
measurement of important electrical parameters like AC voltage, AC Current, Frequency,
Power, Energy(Active / Reactive / Apparent) . The instrument integrates accurate measurement
of technology (All Voltage & Current measurements are True RMS upto 15th Harmonic) with
320x240 Pixels touch screen TFT LCD display.
This instrument can be congured and programmed at site for the following: PT Primary, PT
Secondary, CT Primary, CT Secondary (5A or1A) and 3 phase 3W or 3 Phase 4W system.
The front panel has a 3.5” Touch Screen through which the user can move across the available
measurement readings, reset the energy, Min/Max (System Voltage and System Current) and
congure the product settings.
Main menu is divided into 6 submenus. Each submenu contains a list
of options. By touching the icons on main menu, submenus can be
accessed. System submenu can be used to access RTC, harmonics,
Power Quality events and other system parameters like system
power, min, max voltage and current, THD, run hour, on hour and
number of interruptions. Voltage, current and power submenu contain
measurement of basic elecrical parameters. Energy submenu gives
the total energy and Setup submenu can be used for complete meter
settings.

3.1. Password Protection
Password protection can be enabled to prevent unauthorised access to set-up screens, by
default password is “0000”.
Password protection is enabled by selecting any four digit number.
3. Programming
The following sections comprise step by step procedures for conguring the instrument for
individual user requirements. To access the set-up screens touch on the “ SETUP ” icon in
Main Menu. This will take the User into the Password Protection Entry Stage(Section 3.1).
After touching “ SETUP” icon Password protection screen is
displayed. Screen consists of 0 to 9 digit input keypad for entering the
password very similar to any calculator in touchscreen mobile.“Enter
Password” is displayed on screen at start so that user can enter
password using displayed keypad.
Touching “ key” will display 1 in display area, similarly user can
enter remaining 3 digits.
For deleting any digit while entering password, user can touch “ key”.
After entering the complete password user needs to conrm password by touching “ key’’.
DEL
ENTER
ENTER

If Entered password is correct then “Password Accepted” is displayed on screen & user will on
screen & user will enter into setup menu.
Password conrmed.
If Entered password is wrong then “Password Rejected” is displayed on screen & user need to
re-enter the password After wrong password is entered, user needs to touch “ key ” for
trying another password.
Password Incorrect.
12

Change Password Option is the second last option in list of “SETUP”
submenu, so can be accessed by a simple touch on “ Change
Password” button.
In this screen user rst needs to enter the current password.
3.1.1 Change Password
After input of correct password,“PASSWORD ACCEPTED”is
displayed & now user can enter the new 4 digit password.
After entering new password user needs to touch “ key” to
conrm.
After conrming “PASSWORD CHANGED” is displayed on screen,
which ensures successful changing of the password.
New Password conrmed.
3.2 Menu selection.
After entering in the SUBMENU 6 - SETUP, user will be asked to enter password & after
input of correct password list of following parameters will be displayed on screen :-
ENTER
13

Touching on SYSTEM PARAMETER will open the system parameters list screen.Then these
screens from particular parameter may be scrolled through one at a time in incremental order
by touching the “ key” and in decremental order by touching “ key” on given touch
screen.
3.2.1 System Parameters Selection
After entering in the “SYSTEM PARAMETERS”, List of following parameters will be displayed :-

3.2.1.2 Potential Transformer Primary Value
The nominal full scale voltage will be displayed as Line to Line Voltages for 3 Phase 3 wire and
3 Phase 4 wire and 1 Phase 2 wire for Single Phase.
This screen can be accessed only from system parameters list menu.
Here again 0 to 9 digit input keypad is provided to set value of PT
Primary, & user can conrm this value with a simple touch “ key”.
“ key” is used to multiply value by 1000.
In case presently displayed Potential Transformer Primary value
together with the Current Transformer Primary value, previously set,
would result in a maximum power of greater than 666.6 MVA per
phase,”Invalid value” will be displayed. Then the valid range will be
displayed.
Valid range of PT primary setting value is
100V L-L to 692.8KV L-L.
If value outside the range is entered, It will display “INVALID VALUE”
followed by correct range of parameter.
Note : Changing PT Primary would erase the Sag and Swell data of
PQ events.
3.2.1.1 System Type
This screen is used to set the system type.
Two types: 3 phase 3 wire & 3 phase 4 wire system are displayed on
screen (for RM3440i). Touching radio button in front of particular type
will select that type.
Touch on “ key” will conrm the system type.
Touching the “ key” will keep the old selected setting and will
return to previous menu.
Note : If system type is changed, relay parameter selection & analog output selection will be set
to NONE and all the PQ event data (sag/ swell/ overcurrent) would be erased.

The Valid range of instrument is from 100 to 600V.
If value outside the range is entered, It will display “INVALID VALUE”
followed by correct range of parameter.
Note : Changing PT Secondary would erase the Sag and Swell data
of PQ events.
3.2.1.3 Potential Transformer secondary Value
The value must be set to the nominal full scale secondary voltage which will be obtained from
the the Transformer when the potential transformer(PT)primary is supplied with the voltage
dened in 3.2.1.2 potential transformer primary voltage. The ratio of full scale primary to full
scale secondary is dened as the transformer ratio.
This screen can be accessed only from system parameters list menu. Here again 0 to 9 digit
input keypad is provided to set value of PT Secondary, & user can conrm this value with a
simple touch on “ key”.

3.2.1.4 Current Transformer Primary Value
The nominal Full Scale Current that will be displayed as the Line currents. This screen enables
the user to display the Line currents inclusive of any transformer ratios, the values displayed
representthe Current in Amps.
This screen can be accessed only from system parameters list menu.
Here again 0 to 9 digit input keypad is provided to set value of CT
Primary & user can conrm this value with a simple touch on “ key”
and “ key” is used to multiply value by 1000. In case presently
displayed Current Transformer Primary Value together with the
Potential Transformer Primary Value results in a maximum power of
greater than 666.6 MVA, “invalid value” will be displayed. Example: If
primary value of PT is set as 692.8kV L-L (max value) then primary
value of Current is restricted to 1157A.

3.2.1.5 Current Transformer Secondary Value
This screen is used to set the secondary value for Current
Transformer. Two options: 1 AMPERE & 5 AMPERE are displayed on
screen. Touching radio button in front of particular option will select
that option.
Touch on “ key” will conrm the setting. Touching the “
key” will keep the old selected setting and will return to previous
menu.
Note : Changing CT Secondary would erase the Overcurrent data of
PQ events.

The “Maximum Power” restriction of 666.6 MVA refers to 120% of nominal current and 120% of
nominal voltage, i.e, 462.96 MVA nominal power per phase.
Valid range of CT primary setting value is from 1 to 9999. If value
outside the range is entered, It will display “INVALID VALUE” followed
by correct range of parameter.
Note : Changing CT Primary would erase the Overcurrent data of PQ
events.

3.2.1.8 Auto Scrolling
This screen allows user to enable screen scrolling. Seven options :
ALL, SYSTEM, VOLTAGE, CURRENT, POWER, ENERGY & NONE
are displayed on screen. Touching radio button in front of particular
option will select that option. Selecting particular option means, only
screens which are under that submenu will be scrolled automatically.
Selecting NONE will disable Auto-Scroll.
Touch on “ key” will conrm the setting.
Touching the “ key” will keep the old selected setting and will return to previous menu.
While in Auto-scrolling mode, touch sense for entire screen will be disabled except for the top
right most corner where “A” symbol would be displayed stating that meter is in Auto-scroll mode.
Touching on “A” will show two options “ON” and “OFF”. Touching on “ON” will continue auto
scrolling & touching on “OFF” will stop auto-scrolling & return to normal mode.
