8.1 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
total
= P
L1
+ P
L2
+ P
L3
P
total
> 0: counting energy for +A
P
total
< 0: counting energy for -A
8.1.1 Instantaneous parameter measurements
The instantaneous values can be read out via RS485 interface.
● Voltage and current
● Power factor
● Active power
● Frequency
8.2 Display Modes
The meter support three different display modes:
- AUTO Mode
- ALT Mode
