currents. In networks with high harmonics, the second method is

(called non-active power) is calculated as:
Configuring Digital Inputs
The PM130 PLUS can be provided with four, eight or twelve digital inputs
that can be linked to control setpoints to give an indication on input status

Counters). They can also be linked to the Billing/TOU registers to count
pulses from external wattmeters or gas and water meters.
