Linear Bar Graph Displays
The linear bar graphs are arranged in a
three by three matrix on the right half of
the display. A typical layout is depicted
here (Note: your actual configuration may
vary). Typical functions that can be
displayed are:

Oil temperature

Oil pressure

Fuel pressure

Bus voltage

Amps (charge/discharge shown)

OAT

Fuel flow

Left tank fuel quantity *

Right tank fuel quantity *
* The fuel quantity gauges will not be functional until the fuel calibration process has
been completed.
The range of the bar graphs depends on the programming. Range,
redlines and/or limits are typically set to match the original aircrafts
gauge markings. These are locked for Primary installations, however
non-primary gauges can be user modified, using ‘EDM Config’ which is
currently available through the front panel buttons. Editing of Gauge
Layout requires EDM Software version 1.20.489 or later. Note: Amps
can operate either as a charge/discharge or load meter, depending on
programming. For charge/discharge, the center of the bar is zero and the
top and bottom are maximum charge and discharge, respectively.
