CO-GENERATION
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 16.8.1). If this flag is enabled the maximum
number of parameters which can be selected decrease
to 38.
OFF = the instrument will record ONLY the powers and
energies absorbed.

The value of the network frequency is automatically selected if at least one phase voltage (for the
single-phase mode or the 4 wires three phase mode) or at least one phase-to-phase voltage (for the 3
wires three phase mode) is selected.
The symbols "i" and "c" stand for reactive powers (Q), power factors (Pf) and cos

(dpf) inductive and
capacitive respectively.
Selecting a power factor (Pf) or a cos

(dPf) for the recording automatically their inductive value and their
capacitive value will be recorded separately.
