4.- OPERATION
The line-CVM-D32 device is a power analyser for all four quadrants (consumption and generation).
The device can operate under three different measurement conventions:
Measurement convention CIRCUTOR.

Measurement convention IEC.

Measurement convention IEEE.

The measurement convention is configured using the configuration menu, see
