Note: The power factor is a measure
of the ratio of the actual (real power)
and the theoretical (apparent power)
power of an electrical device. The
power factor can have any value
between 0 and 1. The ideal value is 1.
When the power factor is less than
1, power is exchanged between the
electrical appliance and the grid. In
exceptional cases, this can lead to
display of the power factor and the
power being unstable, depending on
the power level and the value of the
power factor. This is due to technical
reasons and is unavoidable. The en-
ergy cost monitor correctly determines
the energy used. The mean value
around which the changing value
displayed hovers represents the cal-
culated value of the current power or
the current power factor.
