Resetting ‘ USED’
USED is automatically reset whenever you perform REFUEL on your
EDM (except if TRIP mode = yes).
After filling your tanks and prior to engine start you should inform the
EDM that the aircraft has been filled. In this case USED is automatically
set to zero.
If you forgot and have already started the engine, and then you inform
the EDM that tanks have been filled, then some fuel has already been
used. Not to worry as the EDM will automatically set USED to this
amount and also subtract it from the REM value, keeping the two values
in balance.
To manually zero the amount of fuel USED at any time, manually
STEP to display USED and then hold both DIM (button 3) and EGT/FF
(button 4) until the display shows ‘.0 USED’ (this normally takes
about five seconds)
.
Trip Mode (Accumulate Trip Totalizer)
Trip mode is typically used if you want to track the total fuel used over a
multi-stop cross country. To have the USED parameter continuously
accumulate total consumed fuel, set TRIP? Y. ‘Trip Mode’ is described
in the ‘Program Mode section’. Note: typically, TRIP? is set to ‘N’ so
that USED will be reset every time you fuel the aircraft
Scanner Fuel Flow Display Select
Button four selects three different Scanner filters - ALL, EGT or FF.
Tapping this button will select the next choice (shown after the ‘/’
symbol):
• ALL/EGT: all installed parameters are shown in Scanner.
• EGT/FF: only the installed temperature (and battery voltage)
parameters are shown in Scanner.
• FF/ALL: only fuel flow parameters are shown in Scanner.
Note: Scanner filter or mode selection does not affect Alarms or analog
displays.
