Communication Ports

These two menus allow you to configure parameters for communication
ports COM1 and COM2. To enter the menu, select "Prt.1" for COM1 or
"Prt.2" for COM2 from the Main menu, and then press the ENTER button.
To select a setup option:
1. Press the SELECT button to activate the middle window.
2. Use the UP and DOWN arrow buttons to scroll to the
desired option.
To change the option:

Description
The ratio of the true
transformer ratio to the
marked ratio.
The phase
displacement, in
minutes, between the
primary and secondary
values. The phase angle
of a voltage transformer
is positive when the
secondary value leads
the primary value.
The ratio of the true

The phase
displacement, in
minutes, between the
primary and secondary
values. The phase angle
of a current transformer
is positive when the
secondary value leads
the primary value.
