Measurement

The meter measures three phase active energy with accuracy class B.
The meter provides registers for total import, total export and net energy.
Additionally, each phase L1, L2 and L3 for import and export energy are measured.
The measurement of the energy is based on the measured power according the following cal-
culations:
P

Instantaneous parameter measurements

The instantaneous values can be read out via RS485 interface.
● Voltage and current
● Power factor
● Active power
● Frequency
