Scale Factors
Note: These registers contain a signed integer,
which scales the corresponding integer registers.
Floating point registers are not scaled. Scaling
is recalculated when the meter configuration is
changed.
139 R SInt Scale Factor V (Voltage)
140 R SInt Scale Factor W (Power)
141 R SInt Scale Factor E (Energy)
142 R/W NV UInt % 1-99
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.
Phase Loss Output
Note: The phases tested are determined by the
System Type.
143 R/W NV UInt % 1-99
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 Δ 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.

Pulse Contact Closure Duration
in msec. Read-only. Set to the
slowest duration that keeps
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.
