Section 4 - Operating Modes
The EDM has four basic operating modes: Automatic, Manual, Program
and LeanFind. LeanFind is described in the next section; Program mode
is described on page 38, ‘First Time Setup and Customization’. When
you first turn on the power the EDM starts in the Manual mode, but will
enter the Automatic mode after a few minutes. The Automatic mode
provides you with engine monitoring information for the majority of
flight conditions. To optimize the mixture, use the LeanFind mode. To
display specific parameters, use the Manual mode. In either Automatic
or Manual modes, the display always shows the Scanner bar graphs for
EGT and CHT for each cylinder and TIT (if so equipped).
Automatic Mode
To activate Automatic Scanner Mode, just tap the LF button, then
tap the STEP button. In the Automatic mode the EDM changes which
measurement is displayed every four seconds (factory default is ‘Auto
Scan Rate 4’), however you can change this rate in the Program Mode.
A setting of zero disables auto scanning altogether.
Some non-primary measurements can be excluded from the Automatic
mode: tap
STEP to enter the Manual mode. Tap STEP repeatedly to index
to the measurement you want to exclude. Then tap both the STEP and LF
buttons simultaneously. Excluded measurements display a decimal point
before the measurement name. For example:
Included: 1540 CDT Excluded: 1540 ● CDT
Tapping the STEP and LF buttons simultaneously will toggle back and
forth between include and exclude. Note: All measurements are always
checked for alarm conditions every second.
 Every time you turn on the EDM, all measurements are reset to be
included.
 All installed measurements are always displayed in the Manual
mode. Exclusion only applies to the Automatic mode.
