OPERATION
VOLTAGE is displayed both
graphically
and digitally.
Full color range
marks
provide
a
quick
reference for fast
analysis
of vollage levels.
As
voltage
rises,
the
graph
size
increases
proportionately.
The
digital
readout
displays
voltage at
0.1 volt resolution.
This is
useful for troubleshooting.
Additionally
your
system
has
a built-in warning
system
that flashes
the
graph
when system
voltage
is out
of nominal range
(either
too
low
or
too high)
.
AMPERAGE
is displayed
both
graphically
and digitally.
Full
color
range
marks
provide
a
quick
reference
for
fast
analysis
of
amperage
levels.
As amperage
rises,
the
graph
size
increases
proportionately.
The
digital
readout
displays
amperage
at
1
amp
resolution.
This is
useful for
troubleshooting.
You
should
see
an increase
on
the amp
displays
when
you
turn
on a
load,
such as
pitot
heat
for
example.
This
tells
you
that the
pitot
heater
is
drawing
power
and is
probably
OK.
By
verifying
that
voltage
remains
the same,
then it
can be
assumed
that
the
alternator is
supporting the
additional load.
A
very
handy
feature
for
in-flight
testing
I verification
of electrical
loads
and
the
alternator
charging
system.
Additionally
your
system
has
a
built-in
warning
that flashes
the
graph
and
triggers
the audio/visual
annunciator
system
(if
installed) when
the
alternator does
not
produce
power
for the
electrical
system. This
occurs at
low amperage
levels
of approximately
less
than 2 amps.
