2 quadrants
Only the energy consumed by
the installation is recorded.
Absolute Measure (ABS)
They record the absolute value of
the energy, adding the total energy
consumed and energy generated
and showing it as a single value.
4 quadrants
Records both the energy consumed and
generated in two independent logs.
