11. 2 Current transformer ratio
You can set the current transformer ratio
for the baseline measurement using
addresses 000 and 001.
You can use addresses 010 and 011
to set the current transformer ratio for
the supporting measurement.
A current transformer ratio of 5 A / 5 A is
factory-set for all 4 current transformer inputs
in the factory.

11. 3 Voltage transformer ratio
You can use addresses 002 and 003 to set
the voltage transformer ratio for the baseline
measurement.
You can use addresses 012 and 013
to set the voltage transformer ratio for
the supporting measurement.
A voltage transformer ratio of 400 V / 400 V is
factory-set for all 4 voltage transformer inputs
in the factory.
