Ct ratio primary

131
Ct ratio secondary interface (1 or 1/3 v, may not be user configurable)
word
132
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)
word
133
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)
word
134
Theoretical maximum system power: this read only value is the theoretical maximum 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)

Display units: 0 = iec (u, v, p, q, s), 1 = ieee (default: vll, vln, w, var, va)

Scale factors note: these registers contain a signed integer that scales the corresponding integer registers. floating point registers are not scaled. scaling is recalculated when the meter configuration is changed
