Appendix B: Additional Diagnostic Functions
Vibration Check
The
Vibration
Check
tests
the
level
of
vibration
or
movement
in
the
checkstand
and
scanner/scale.
There
is
no
pass/fail
point
for
this
test;
it
can
only
be
used
as
a
diagnostic
tool.
Perform
the
following
procedure.
1.
Remove
power
from
the
RealScan
74.
2.
If
the
RealScan
74
does
not
have
a
RealScan
25
Remote
Customer
Display,
remove
the
Tower
Cabinet
and
connect
the
Field
Service
Calibration
Display
to
the
display
connector
on
the
Digital
Board.
3.
Apply
power
to
the
RealScan
74.
4.
Scan
the
Diagnostic
Mode
tag
to
enter
the
Base
Diagnostic
state—must
be
first
tag
scanned
after
applying
power
to
the
RealScan
74.
5.
Scan
the
Hex
4
tag,
then
the
Hex
1
tag
to
enter
the
Vibration
Check
test.
6.
Place
a
small
weight
on
the
scale
(for
example,
a
medium
size
coin).
7.
Watch
the
display
for
10
to
15
seconds
and
note
the
range
of
readings.
8.
If
the
readings
vary
more
than
±
0.001
kg
(±
0.004
lb),
there
may
be
a
problem.
9.
If
possible,
move
the
RealScan
74
to
a
known
stable
location
(like
the
floor)
and
take
measurements
again.
a.
If
the
readings
vary
less
than
they
did
in
the
checkstand,
the
vibration
is
probably
in
the
checkstand.
This
could
be
the
result
of
belt
motors,
ventilation
fans,
and
so
forth.
b.
If
the
readings
are
about
the
same,
the
problem
could
be
in
the
RealScan
74.
If
you
need
assistance
resolving
this
problem,
contact
the
Retail
Global
Support
Center.
10.
After
using
this
diagnostic
check,
remove
power
from
the
RealScan
74
to
end
the
test.
11.
If
a
Field
Service
Calibration
Display
is
used,
disconnect
it
and
install
the
Tower
Cabinet.
