The CVM-A measures, calculates, displays and records the main electrical parameters and
the quality parameters in single-phase networks, two-phase networks with and without neutral,
balanced three-phase networks, with ARON

measurement or unbalanced. The measurement
is taken in TRMS, via four AC voltage inputs and four or three current inputs (according to ver-
sion).
There are 2 device models:
CVM-A1000, with a 3.5’’ display.
CVM-A1500, with a 5.6’’ display.
There are 2 versions of the device depending on the current input:
CVM-A1x00-ITF, the current is indirectly measured using /5, /1 A transformers or efcient
MC1 and MC3 series transformers and an input for neutral current measurement.
CVM-A1x00-FLEX, current measurement using Rogowski sensors. As there is no meas-
urement input, the device calculates the neutral current.
