3.3: Display Information
The Nexus® 1262/1272 meter uses a graphical back-lit FSTN LCD Programmable Display with extend-
ed temperature voltage compensation. This allows you to view energy data and to gather circuit diagnos-
tic data such as voltage, current, harmonics and phasor information.
A wide range of values can be defined for display using the User Modes and screens in the
Programmable Display and Communicator EXT software. Three View Modes, plus Test Mode and a
Select Compensation Screen allow tremendous flexibility in setting up the Display modes and the
screens within the modes. View Modes are user created with up to 16 screens each, which display in
auto sequence every 7 seconds. Most of the screens have a Status Bar across the bottom which displays
the date, time and phase (if there are inputs). View Mode 1 is the primary mode. The other modes will
automatically return to View Mode 1 after a user-set amount of time from last user action.
