Display Modules
A Display module controls which values are displayed on a display screen, and
how these values are presented. Depending on your meter model, the Display
modules vary slightly according to the inputs utilized and the setup register
settings. Each Display module corresponds to one meter display screen.
Display Modules for ION 8000 Series, ION 7500 /
ION 7600 Meters
The Display module’s Source inputs are linked to the numeric parameters you
want to display. These parameters are sent to the front panel when the Display
module’s Show input is pulsed.
The Display module’s setup registers determine screen type (e.g. numeric, event
log, trend bar etc.), softkey name and number (if applicable), and screen title (if
applicable) of each display. Many Display modules available in the meter are used
in the factory configuration. You can alter some characteristics of the factory-
configured displays by modifying the setup register of the Display modules.
The Display module’s setup registers determine how the Source data is presented
on the front panel display. Depending on the display screen type, which is
specified by the Screen Type setup register, you can use up to twenty Source links
to a single Display module. This means you can show the values of up to twenty
different sources on one front panel display screen. In addition, you can display
harmonics, trending, and event logs (see the Screen Types column in the table
below). For additional information about screen types, consult the section Display
Screen Types in your meter’s user guide.

If you alter the Screen Type setting to a display type that accommodates more numeric parameters, you
may have to create additional
Source links.

The ION 7500 / ION 7600 meters displays all of these parameter groupings; the ION 8000 Series
displays parameter groupings of two, three, or four.
