Overview of meter functions
The meters provide the essential measurement capabilities (for example, current, voltage, and
energy) required to monitor a 1- or 3-phase electrical installation.
The key features of the meters are:
• measurement of active and reactive energy,
• Multi Tariffs (up to 4) controlled by internal clock, digital inputs or communication,
• MID compliance for many of the meters,
• pulse outputs,
• display (current, voltage, and energy measurements),
• communications via Modbus, LonWorks, M-Bus or BACnet protocols.
