2. The FOCUS Meter Family
The FOCUS provides more than just reliability and accurate billing data. The FOCUS is designed to be
a building block for a complete metering system. Each
FOCUS has built-in compatibility for a variety of
AMR packages. Any of these can be factory installed. Some can be added to the meter dependent
upon the meter vintage and respective AMR technology.
Register Types
The Focus kWh is an active energy “kWh-only” meter. It is capable of measuring and displaying
kilowatt-hours delivered to and received from a load.
The energy accumulation register has capacity to display 999999 kWh for all meter forms without
overflowing.
The meter supports four energy metric displays:
• +kWh (energy delivered to the load)
• -kWh (energy received from the load)
• NET kWh (the net energy consumed by the load, or negative kWh subtracted from positive
kWh)
• ADDED kWh (negative kWh added to positive kWh-also referred to as
security mode)
