Introduction
ION meters ship with preconfigured display screens. Most users find that the data
displayed by the front panel LCD (Liquid Crystal Display) suits their needs
entirely. However, front panel displays may be customized on most ION meters.
ION meters’ display screens can be customized to show virtually any measurement
or calculation of which the meter is capable. For example, you could do one or all of
the following:
◆ change displayed parameters, such as from Vll to Vln or Vllab to Vlna
◆ aggregate displays from multiple meters, such as using a meter’s front panel
display to view data collected by one or more TRAN units (see the section titled
“Displaying Data from Other Meters” on page 206)
◆ adjust character size to be different on each screen
◆ change data display settings such as backlight timeout, automatic display
scrolling, parameter update rate and display mode*
* The display mode setting is not available for ION 7300 meters.
In order to customize your front panel display screens, you must make changes to
ION modules that belong to the display framework. After briefly summarizing the
functions of these ION modules, this document explains how you customize your
meter using Designer software.
ION Modules in the Display Framework
There are three particular ION modules that control the front panel display:
◆ the Display module
◆ the Display Options module
◆ the Scroll module
Refer to the online ION Programmer’s Reference for complete details on these
modules, including descriptions of their inputs, setup registers, and output
registers.

The online ION Programmer’s Reference details all of the registers belonging to a particular ION module,
but not every register is employed in the various series of meters. Only those registers applicable to the
meter’s module configuration appear in Designer.
