1) The average over 3 phases can only be called via the communication interfaces or the user defined display.
2) Total reactive power (VARtot), comprising the reactive power of the fundamental (VAR1) and the reactive power of the
harmonics (VARn).
3) Reactive power of the fundamental (VAR1) due to the displacement of voltage and current
4) Reactive power of the harmonics (VARn) without the fundamental content due to the power system harmonics (integer
multiples of the fundamental frequency)
5) Inductive and capacitive.
6) Off-peak or on-peak. The current tariff is shown on the display.
7) The "+" sign stands for "Import". The "-" sign stands for "Export".
8) Optionally calculated for total reactive power (VARtot), reactive power (VARn), or reactive power (VAR1).
9) The unit depends on the settings: User definable unit or "kWh" or "kVARh" for the pulse counter function.

Measured variables depending on the connection type
The total set of representable measured variables is restricted by the method of connecting
the device.
A measured value that cannot be indicated because of the connection method is shown on
the display by means of a broken line "----".
The table below shows which measured values can be represented depending on the
connection type.
