Set Potential Transfomer Ratio:
RATIO – Potential transformer step down is RATIO:1. Default is 1:1
(No PT installed). See Install for wiring diagrams. This value must be
set before the System Voltage (if used).
Set System Voltage:
V LL – The nominal Line to Line Voltage for the system. This is used
by the meter to calculate the theoretical maximum system power, and
as the reference voltage for setting the Phase Loss threshold.
Maximum is 32000 Volts. For system type 1+N (10), this is a Line to
Neutral Voltage, indicated by "V LN". Note: the meter will reject settings
that are not within the meter's operating range when divided by the PT
ratio.
System Power:
MX KW – The theoretical Maximum System Power is calculated by the
meter from the System Voltage, CT size, and System Type. Power
Factor is assumed to be unity. The value of System Power is used to
determine which combinations of pulse weight and duration are valid
and will keep up with the maximum power the meter will see. This value
is read only.

ADDR - Modbus Address: 1 – 247.
