mode. And to display specific measurements, use the Manual indexing
mode. In both the Automatic and Manual indexing modes the analog
display shows a bar graph of EGT and CHT for each cylinder and the
TIT, if installed (or Oil temperature, if it is installed and TIT is not
installed).
Automatic Indexing Mode
Just tap the LF button, then tap the STEP button. No user intervention
is required to use this mode. In the Automatic indexing mode the EDM-
760/790 displays the measurement sequence at a user-selected indexing
rate (see “Personalizing” on page 40).
Individual measurements can be excluded from the Automatic indexing
mode: tap STEP to enter the Manual indexing mode. Tap STEP 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 I84 OIL Excluded I84
OIL
Tapping the STEP and LF buttons simultaneously will toggle back and
forth between include and exclude.
You can program whether every time you turn on the EDM-760/790,
it will remember which measurements were excluded or defaults to
none excluded. See on page 49.
All installed measurements are always displayed in the Manual
indexing mode. Exclusion only applies to the Automatic indexing
mode.
All measurements are checked for alarm conditions every second
regardless of their included or excluded status.
Manual Indexing Mode
Just tap the STEP button. Use the Manual indexing mode when you
want to monitor one specific measurement such as shock cooling during
descent, or a particular cylinder temperature during climbs. To change to
the Manual indexing mode, tap the STEP button once. Subsequent taps
