2.- MAIN FEATURES

The

CVM 96

power meter is a programmable measuring instrument, offering

several operation possibilities selectable in its SETUP option. Before power supplying
the instrument, read the

CONNECTIONS and SETUP

sections and choose the most

suitable operation mode for getting your desired data.

The

CVM 96

is an instrument which measures, calculates and displays all the

main electrical parameters at any electrical network (balanced or not). The measuring
is true RMS value, through three a.c. voltage inputs and three a.c. current inputs
(from Current Transformers .../ 5A).
