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
measured over preset periods of up to 60 minutes.
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

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).
