5.40 Material Rigidity Selector
The Material Rigidity Selector permits the user to set the
DTMX for use on Textiles or Wires. It is used in the com-
puter calibration formulas to provide the highest mea-
surement accuracy. If using a process material other than
a Textile or Wire, choose the setting which best matches
the rigidity (stiffness) of the process material. If uncertain which setting is
best, check the calibration in each position and choose the one providing the
best accuracy. Refer to Checking Calibration, Section 8.10.
The Material Rigidity Selector is also used to select a special calibration (SP1
or SP2) which is optionally available. Refer to Special Calibration, Sec. 8.30.
5.50 Thickness Compensator
When using the "three-roller" principle of tension measurement, an increase
in material diameter will result in an increased tension reading even when the
line tensions are unchanged. The DTMX is supplied with a proprietary
Thickness Compensation system which automatically shifts the outer rollers to
compensate for this effect. Additionally, the Thickness Compensator measures
the material diameter with an accuracy of 0.01 mm (0.0004 ") for use as a fac-
tor in the com-puter calibration formula.
The Thickness Compensator is located on the back of the instrument. When
the Thumbpiece is pushed forward, two metal plates (anvils) will separate cre-
ating a slot for insertion of the material sample.
NOTE: 1. Some monofilaments, wires and other
difficult-to-bend samples will need special prepa-
ration prior to insertion into the Thickness Com-
pensator. See Preparing Sample for Thickness
Compensator.
2. It is unnecessary to use the Thickness
Compensator on the DTMX-200 because the
range of material diameters used with this
model is inconsequential.
