1.Introduction
This document provides operating, maintenance and
installation instructions. This unit measures and displays
the characteristics of single phase two wires(1p2w),three
phase three wires(3p3w) and three phase four wires(3p4w)
networks.The measuring parameters include voltage(V),
frequency(Hz),current(A),power(kW/Kva/Kvar), mport, i
export and total Energy(kWh/kvArh).The unit can also
measures Maximum demand current and power. his is T
This unit is a 1A or 5A current transformer operated and can
be configured to work with a wide range of CTs. Built-in pulse
and Modbus or M Bus 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 by linking the voltage reference and neutral reference in
to terminals 5 and 6 (Please refer to wiring diagram).
1.1 Unit Characteristics

• Voltage and THD% (total harmonic distortion) of all phases
• Line frequency
• Currents,current demand and current THD% of all phases
• Power, maximum power demand and power factor
Active energy import d and exportede
• Reactive energy imported and exported

the first digit and press
to confirm your
selection. The next digit
will flash.
Repeat the procedure for
the remaining three digits.
After setting the last digit,
SET will show.
Press
to exit the number setting routine and return to the
Set-up menu. SET will be removed.
4.3 DIT Demand Integration Time
This sets the period in minutes over which the current
and power readings are integrated for maximum demand
measurement. The options are: off, 5, 10,15 30,60 minutes.
From the set-up menu, use
and buttons
to select the DIT option.
The screen will show
the currently selected
integration time.
Press to enter the
selection routine. The
current time interval will
flash.
Use and
buttons to select the time
required.

main set-up Menu.
4.5 CT
The CT option sets the secondary current (CT2 1A or 5A)
of the current transformer (CT) that wires to the meter.
From the set-up menu,
use and buttons
to select the CT option.
Secondary CT setting
Press to enter the
CT secondary current
selection routine.:5A/1A
4.6 PT
The PT option sets the secondary voltage (PT2 100 to 500V) of
the voltage transformer (PT) that may be connected to the meter.
and buttons
to select the PT option.
The screen will show the
voltage PT secondary
voltage value. The default
value is 230V.
Secondary PT setting
Press to enter the
PT secondary voltage
selection routine. The
range is from 100 to 500V.
For example, if set the ratio to be 100,it means the primary
voltage equals secondary voltage x100.

Set CT Ratio value
Press to enter the
CT Ratio setting screen.
The range is from 0001
to 2000.
For example, if using a 100/5A current transformer you
will enter 0020, as you need to divide the primary by the
secondary to get the ratio (CT rate).
Set PT ratios value
Press to enter the PT
ratio screen.
The range is from 0001
to 9999.
As an example: If using 100/5A CT, you will need to insure
CT2 (Secondary) is set to 5 and CT rate is 0020. You divide
the primary by the secondary to get the CT rate to be entered
(100/5=20).
