Circutor CVM-C10 - OPERATION; CIRCUTOR MEASUREMENT CONVENTION; IEC MEASUREMENT CONVENTION; IEEE MEASUREMENT CONVENTION

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 congured in the setup menu, see “4.9.8. Measurement con-
vention”.
 CIRCUTOR. measurement convention
