4.1.2 Energy measurements
The meter provides fully bi-directional, 4-quadrant energy metering. The meter stores all
accumulated active, reactive and apparent energy measurements in nonvolatile memory.
Energy accumulated was from the last reset until the current moment.
4.1.2.1 Energy metering is full-wave based calculation is used to accumulate
energy including fundamental and harmonics.
4.1.2.2 The reactive energy(power) calculating is:
4.1.2.3 Energy metering is primary energy.
4.1.3 Auto wire change
The Meter voltage and current wiring is a matching requirement. For example, V1, V2
and V3 need to correspond to I1, I2 and I3, and the input direction of current is also the
same. For example, input I11 and
fl
ow out I12. In actual use, wiring errors may occur. In
this case, you can compensate for the wiring errors through the meter's auto wire change
function to obtain the correct measurement results without changing the wiring.
4.1.3.1 Into the auto wire change function, the
fi
rst choice of power system mode.
4.1.3.2 After meter calculation, confirm the
active power value is correct, if correct, choose
Yes to continue, if not choose No, the meter will
recalculate or display the message to inform the
adjustment of voltage wiring recommendations.
