To increase accuracy in the fuel flow measurement you must
calibrate the transducer by following this steps.
NOTE: it's recommended to perform the calibration right after
installing the Remote module and repeat it once a year.
1- With the aircraft in level attitude, fill the tank/s of fuel; note
that in the step #4 it's required to refill the tank/s at the
exact level reached here.
2- Turn-on the Vigilus and select “ FILLED ” when asked for
the fuel quantity.
3- Burn at least 3/4 of fuel in the tank/s: a greater amount of
burned fuel will increase the accuracy, and you can do
this step in more flights: at the start of each flights you
must not add fuel in the tank/s and you must select “ NO
REFUEL ” when asked after turning on the Vigilus.
4- Fill the tank/s with the exact same level reached in the
step #1, accurately measuring the quantity of fuel added
in the tank/s.
5- Turn on the Vigilus and select “ NO REFUEL ” (even
though you have refilled it’s required to select “ NO
REFUEL ”).
6- Enter in the Main menu → Settings → Fuel Computer →
Calibration; the following screen will appears:
