R/W NV UInt
100
0.01-320.00 PT Ratio: The meter scales this value by 100 (i.e. entering 200 yields a potential transformer ratio of 2:1). The
default is 100 (1.00:1), which is with no PT attached. Set this value before setting the system voltage (below)
134
R/W NV UInt
82-32000
System Voltage: This voltage is line to line, except for system type 10 which is line to neutral. The meter uses
this value to calculate the full scale power for the analog outputs and pulse configuration (below), and as full
scale for phase loss (register 142). The meter will refuse voltages that are outside the range of 82-660 volts
when divided by the PT Ratio (above).

Theoretical Maximum System Power: This read-only value is the theoretical max. power the meter can expect to
see on a service. This value is 100% of scale on the analog output (0-5 Vdc or 4-20 mA), if equipped. The meter
recalculates this value if the user changes the CT size, system type, or system voltage. This integer value has
the same scale as other integer power registers (see register 140 for power scaling).

are not scaled. Scaling is recalculated
