ON = the instrument is able to face situations of CO-GENERATION
of electrical equipment (that is, the equipment under test is
able to generate energy besides absorbing it). Accordingly, the
instrument will record the powers and energies both absorbed
and generated (see paragraph 16.12.1).
If this flag is
enabled the maximum number of parameters which can
be selected decrease to 38.
CO-GENERATION
OFF = the instrument will record ONLY the powers and energies
absorbed.

The value of the network frequency is automatically selected if the voltage is selected.
The symbols "i" and "c" stand for reactive powers (Q), power factors (Pf) and cos
ϕ (dpf) inductive and capacitive respectively.
Selecting a power factor (Pf) or a cos
ϕ (dPf) for the recording automatically their inductive value and their capacitive value will be
recorded separately.
