5.51 Preparing Sample For Thickness Compensator

When using monofilament, wire or other difficult-
to-bend materials, the sample must be prepared
properly before inserting into the Thickness
Compensator. Using the pliers supplied, bend the
sample as noted in the sketch. For monofilaments,
maintain arc “A” as shown, so sample bends into anvils.

5.52 Inserting Sample Into Thickness Compensator

Push the Thumbpiece forward to separate the two anvils. Insert the sample
into the slot and slowly release the Thumbpiece
back to its resting position. The material sample
should be secured between the two anvils. Place
the ends of the sample under the Sample Holding
Clips located on each side of the unit.If the ends
stick up bend them back so they will not present a
safety hazard.

NOTE: In lieu of a sample, an equivalent shim can be inserted into the
Thickness Compensator as long as its compressed thickness is the same as the
process material. The shim should be secured using a spray adhesive on one
side, so it will not fall out each time the Thumbpiece is pushed forward.

5.60 Gravity Correction Procedure (ZERO)

The DTMX is factory calibrated for use in
the right-handed, horizontal position (verti-
cal material path) with the rollers aligned
vertically. When using the DTMX in any
other orientation, a Gravity Correction
Procedure (Zero) should be performed.

Hold the instrument in the measuring posi-
tion and press the and keys simultaneously. The display
will show zero. The DTMX is now ready for use.
