Introduction
This document provides operating, maintenance and installation instructions. The unit measures
and displays the characteristics of single phase two wires (1p2w), three phase three wires(3p3w,)
and three phase four wires(3p4w) supplies, including voltage, frequency, current, power ,active
and reactive energy, imported or exported. Energy is measured in terms of kWh, kVArh.
Maximum demand current can be measured over preset periods of up to 60minutes. In order to
measure energy, the unit requires voltage and current inputs in addition to the supply required to
power the product. The requisite current input(s) are obtained via current transformers(CT).
This meter can be configured to work with a wide range of CTs, giving the unit a wide range of
operation. Built-in interfaces provides pulse and RS485 Modbus RTU outputs. Configuration is
password protected.
This unit can be powered from a separate auxiliary (AC or DC) supply. Alternatively it can be
powered from the monitored supply, where appropriate.
Unit Characteristics
The Unit can measure and display:
⚫Line voltage and THD% (total harmonic distortion) of all phases
⚫Line Frequency
⚫Currents, Current demands and current THD% of all phases
⚫Power, maximum power demand and power factor
⚫Active energy imported and exported
⚫Reactive energy imported and exported
The unit has password-protected set-up screens for:
⚫Changing password
⚫Supply system selection 1p2w, 3p3w,3p4w
⚫Demand Interval time
⚫Reset for demand measurements
⚫Pulse output duration
Two pulse output indicates real-time energy measurement. An RS485 output allows remote
monitoring from another display or a computer.
Current Transformer Primary Current
The unit can be configured to operate with CT ratio between primary current and secondary
current. The secondary CT has two options: 1A/5A
RS485 Serial –Modbus RTU
This uses an RS485 serial port with Modbus RTU protocol to provide a means of remotely
monitoring and controlling the Unit
Set-up screens are provided for setting up the RS485 port.

Pulse output
This provides two pulse outputs that clock up measured active and reactive energy. The constant
for active energy is 3200imp/kWh (Terminals 11&12). The pulse width for pulse 1 (Terminals
9&10) can be set from the set-up menu.
Start Up Screens
1
The first screen lights up all display
segments and can be used as a display
check.
2
The second screen indicates the
firmware installed in the unit and its
build number.
3
The interface performs a self-test and
indicates
the result if the test passes.
*After a short delay, the screen will display active energy measurements.

Setting Up
To enter set-up mode, pressing the button for 3 seconds, until the password screen
appears.
Setting up is password-protected so you must enter the correct password (default ‘1000’) before
processing.
If an incorrect password is entered, the display will show: PASS Err
To exit setting-up mode, press repeatedly until the measurement screen is restored.

Set-up Entry Methods
Some menu items, such as password and CT, require a four-digit number entry while others, such
as supply system, require selection from a number of menu options.
Menu Option Selection
1) Use the and buttons to select the required item from the menu. Selection
does not roll over between bottom and top of list
2) Press to confirm your selection
3) If an item flashes, then it can be adjusted by the and buttons. If not, there
maybe a further layer.
4) Having selected an option from the current layer, press to confirm your selection.
The SET indicator will appear.
5) Having completed a parameter setting, press to return to a higher menu level. The
SET indicator will be removed and you will be able to use the and buttons for
further menu selection.
6) On completion of all setting-up, press repeatedly until the measurement screen is
restored.
Number Entry Procedure
When setting up the unit, some screens require the entering of a number. In particular, on entry
to the setting up section, a password must be entered. Digits are set individually, from left to
right. The procedure is as follows:
1) The current digit to be set flashes and is set using the and buttons
2) Press to confirm each digit setting. The SET indicator appears after the last digit has
been set.
3) After setting the last digit, press to exit the number setting routine. The SET indicator
will be removed.
