voltage
control
of
the
batteries.
The
measured
value
appears
on
the
display.
If
the
batteries
are
well
charged,
the
measured
potential
will
be
between
5,4V
‐
4,4V.
(The
nominal
potential
is
4,8V)
If
the
voltage
is
under
4,4
V
the
batteries
need
replacing.
The
replace
battery
message
will
be
displayed.
If
long
life
batteries
are
used
to
power
the
device
the
