4.- OPERATION
The CVM-C10 is a four-quadrant power analyzer (consumption and generation).
The device can operate according to three different measurement conventions:
CIRCUTOR measurement convention.

IEC measurement convention.

IEEE measurement convention.

The measurement convention is configured in the setup menu, see "4.9.8. Measurement convention".
