2.2.3. Energy calculations
Calculated energy measures (E+, Eq+, E-, Eq-) are based on the
calculated power measures and the internal clock. Energies
flown to both directions are calculated and displayed as
separate values.
Energy information can be obtained as energy pulses through
the contact outputs, too.
