The
ATC
testers
feature
a
supplied
Joint
Simulator
(Fig.A)
that
is
configurable
to
a
wide variety
of
joint
conditions.
The
Joint
Simulator
is
made
up
of
a
series
of
Bellville
Washers
that
allow
the
user
to
pre-configure
the
joint
to
match
the
actual
application
joint
as closely
as
possible.
Each
of
the
Bellville
Washers
is
concave
in
shape.
By
aligning
all the
concave
curves
in
the
same
direction
a
simulated
hard
joint
is
achieved
(Fig.
B). Alignment
of
the
concave
shapes
in
an
opposing
manner
a
simulated
soft
joint
is achieved
(Fig.
C). Differing
combinations
allow
for
simulated
medium
joints
to
be achieved
(Fig.
D).

remove
the
Joint
Simulator
from
its
bag.
Loosen
the
Hex
Screw
and
stack the
Bellville
Washers
according
to
your
joint
condition
needs. Hand
thread
the
Hex Screw
into
the
housing
several
threads. Place
the
square
drive
end
of
the
simulator into
the
female
square
drive
on
