2. Accu-Measure Auto-Calibrating Metrology
The Nexus® 1262/1272 meters are designed for demanding smart grid and intelligent substation applications. They provide one
of the most profound analyses of electricity available in a socket meter. The units offer extensive advanced monitoring features to meet
the most critical power monitoring requirements. Using advanced DSP technology, the Nexus®’ measure immediate and stored revenue
power data coupled with superior power quality and communication. To meet the sophisticated standards required by utility companies
and de-regulated power providers, the Nexus®’ basic package starts where most other meters end. Standard features in Nexus® units
provide the ability to meet advanced metering needs for the future.

3. Configure Custom Display For Any Application
Unique Display Configurator
The Nexus® 1262/1272 is designed with one of the industry’s most
advanced LCD display configuration technologies. With this highly
customizable display, choose from multitudes of pre-programmed
display screens and create fully customized displays for any specific
application. Build, from scratch, user display screens as needed that
provide information on anything the meter measures (which is almost
everything). Use the display to view not only electrical, but water or
gas usage. Also use the meter as an aggregator for total usage.
Provide ambient and transformer temperature or any other desired
critical operational data on the display.
