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.

The accuracy and precision of the Nexus® 1272 coupled with
its extraordinary logging capability makes it an ideal tool for system
performance and reliability analysis. For the first time, users have
the accuracy and precision of a digital fault recorder at the revenue-
metering site without the expense. The Nexus®’ 16-bit accuracy
and resolution for waveform records actually exceeds many digital
fault recorder products. Combine the Nexus® 1272 with EIG’s suite
of software solutions to further expand the level of understanding
