| 129 | Single phase: A + N | | word |
| 130 | Ct ratio primary | Amps | word |
| 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) | kW | word |
| 136 | Display units: 0 = iec (u, v, p, q, s), 1 = ieee (default: vll, vln, w, var, va) | | word |
| 137 | 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 | | smallint |
| 141 | Phase loss voltage threshold in percent of system voltage (register 134). default is 10 (%). any phase (as configured in register 130) that drops below this threshold triggers a phase loss alert, i.e. if the system voltage is set to 480 V L l, the L N voltage for each phase should be 277 v. when the threshold is set to 10%, if any phase drops more than 10% below 277 v, (less than 249 v), or if any L L voltage drops more than 10% below 480 V (less than 432 v) the corresponding phase loss alarm bit in register 146 will be true | % | word |
| 142 | Phase loss imbalance threshold in percent. default is 25% phase to phase difference. for a 3 phase Y (3 + n) system type (40 in register 130), both line to neutral and line to line voltages are tested. in a 3 phase system type (31 in register 130), only line to line voltages are examined. in a single split phase (2 + n) system type (12 in register 130), just the line to neutral voltage are compared | % | word |
| 143 | Wh (and varh, if equipped with fds) energy per pulse output contact closure. if the meter cannot find a pulse duration that will keep up with the max. system power (register 135), it will reject the new value. try a larger value | Wh | word |
| 144 | Pulse contact closure duration in msec. read only. set to the slowest duration that will keep up with the theoretical max. system power (register 135). the open time the closure time, so the max. pulse rate (pulses per sec) is the inverse of double the pulse time | ms | word |
| 146 | Count of energy accumulator resets | | word |
| 148 | Number of sub intervals per demand interval. sets the number of sub intervals that make a single demand interval. for block demand, set this to 1 | | word |
| 149 | Sub interval length in seconds. for sync to comms, set this to 0 and use the reset register (129) to externally restart the sub interval | Seconds | word |
