(1) In the software the power consumption data of both meters is added so you do NOT
have to set which meter covers which power consumption.
Exceptional cases.
You can also use a second power meter if:
-
The power range of one meter is insufficient.
-
The power meter cannot easily be installed in the electrical cabinet.
-
230 V and 400 V three-phase grids are combined (very uncommon), because of
technical limitations of power meters.
