- indirect power energy measurements by interfacing the meter
of the energy supplier (LV or MV/HV connection);
- direct measurements for the instantaneous variables (LV
connection) and indirect measurements for the energy
variables (LV or MV/HV).
In all operating modes it’s possible to add the management of water
and gas meters and the tariff management of the energies both from the
instrument and from external inferfacings. The easy management and
flexibility of WM4-96 is possible thanks to the plug and play modular
technology by Carlo Gavazzi and to a powerful 32-bit µProcessor. Also
the analogue measuring input module can be adapted to the users’
needs: the instrument acknowledges its presence adapting its electric
features and its operating mode accordingly. The following icons will help
the user to identify the instrument’s modifications.

WM4-96: the connecting instrument.
WM4-96 “enjoys communicating”:
• through the wide graphic display and the easily readable
graphs such as the LOAD PROFILES or the harmonic dis-
tortion hystograms;
• through sending and receiving SMS messages by means
of the GSM mobile network. For example, by sending an
SMS message to a pre-defined mobile phone number,
WM496 informs the user that an alarm has been enabled
or disabled; the user himself can ask the instrument, by
an SMS, information about the measured variables.
The manual describes the modification of the menu
in case the measuring inputs module is not installed.
