Circutor CVM-C11 - 4�- Operation

4. OPERATION
The CVM-C11 is a four-quadrant power analyzer (consumption and generation).
The device can operate according to three different measurement conventions:
 CIRCUTOR measurement convention.
 IEC 61557-12 measurement convention.
 IEEE 1459 measurement convention.
The measurement convention is configured in the setup menu, see “6.8.- MEASUREMENT CONVENTION”.
