FUEL LEVEL
SYSTEM
OPERATION
The
fuel tevel
system
operates
automatically,
once
the
'FUEL
LEVEL
SYSTEM
CALIBRATION'
has
been
performed.
The
indicator
displays
a
left,
center, and
right
digital
read-out
of the
gallons
of
fuel
remaining
of
up to
99
gallons
each
tank.
Additionally
the
left

are also
presented
graphically
to
show

of fuel
remaining
for
quick
reference.

lf a
probe
is not
installed
or not
functioning,
that
display
is blanked.
An
unsteady
display
value
should
be suspected
and
possibly
disregarded
as faulty
operation.
A low
fuel
level
alarm
has been
incorporated
into the
system
which
signals
you
when
a minimum
fuel
level
has
been
reached
in
a
given
tank
by
displaying
'Lo' in
the
corresponding
display
area.
This
value
is
picked
at our
factory
but
may
be
changed
upon
written
request
at the
time
fuel
calibration
information
is
submitted
to
us.
2.11.1
FUEL
LEVEL
SYSTEM
CALIBRATION
The
fuel level
system
needs
to
be
calibrated
to
your
fuel tank.
The
procedure
is
very
easy to
perform,
but
will
take
a
little
while to do
accurately.
TIPS:
=)
Flying
the
aircraft
for
10+
hours
befcire
performing
calibration
can result
in
a better
eventual
calibration
as
various
contaminents
etc.
will
be
flushed
from
the
tanks
and
probes.
_r
You
can
do all
tanks simultaneously
by
adding
fuel
increments
to
each of
them
and
following
the
step by step
instructions.
lnstall
