If
several
measuring
runs
are
necessary
to
balance
a
wheel
because
balance
weight
size
and
position
have
to
be
adjusted
repeatedly,
this
is
often
due
to
insufficient
measurement
accuracy.
If
this
is
the
case
the
operator
can
electronically
calibrate
the
rotating
masses
on
the
machine;
which
is
called
User
Calibration.
A
calibration
run
takes
longer
than
a
regular
measuring
r
eadjustment.
Balance
a
wheel,
as
a
NORMAL
weight
mode,
to
less
than
5
grams
per
plane.
Check
in
Fine
mode.
Select
the
“
MODE
”
key
and
the
“precision”
key
together
for
5
seconds.
The
display
shows
“CAL
1”
and
the
unit
beeps.
Spin
the
wheel.
When
done,
the
display
shows
“CAL
2”.
Mount
the
User
Calibration
Weight,
refer
to
Figure
6
‐
2.
Spin
the
wheel.
The
wheel
will
be
braked.
After
a
few
seconds
the
display
equals
Figure
6
‐
3.
The
UC
was
performed
correctly.
‐
Any
(operator)
error
causes
the
program
to
exit
(
7.1.2).
Unscrew
the
Calibration
weight
from
the
flange
and
put
it
back
in
its
designated
place
in
the
calibration
storage
holder.
