The communication
The meter has three separate communication ports All three ports can be used simultaneously Two of them can individually be equipped for any type of communication: radio, GSM, fibre optics, ISDN, PSTN etc. This enables the meter to give real-time information on several parameters of electricity to a local system simultaneously with giving a power company data for invoicing and analysis
The modules
Every meter accepts a number of plug-in cards Cards for measurement, I/O-functions, and communications are available in a number of versions today Several new versions and new types of cards are already planned Every card has its own software Upgrading of the software can be downloaded to the meter just like a patch can be downloaded to a PC Completely new functions can also be downloaded These functions can be made-to-order for a single customer

The functions
This new, full 4-quadrant meter is excellent for revenue metering It provides a number of previously unseen Power Quality graphs, charts and tables among them Harmonics and THD All parameters of electricity are logged The logging, down to minute-based values, enables real-time following of the powernets behaviour Several types of alarm, for instance theftalarm, are included 14 periodical readings can be stored, and read by a PC program or directly on the display Transformer corrections are included
