5.0 CALIBRATION NOTES
The calibration process
involves hanging laboratory
weights from a fixed point,
engaging the vertical line
material which holds the
weights with the tension
meter 3-roller system,
marking a blank dial face
where the scale pointer
comes to rest for each weight used, dividing the spaces
between load “reading” marks and finish marking and
numbering to show calibration marks and “readings”
on the dial face.
The procedure requires specialized skills and the
following material:
1. A load stand to simulate the setup shown here.
2. A set of precision laboratory weights to cover the
tension range of the instrument.
3. Factory “standard” nylon monofilaments as shown
in the Table on page 7.
4. A Special Calibration Fixture and metric wrench.
A full, detailed calibration procedure is available upon
request.
5.1 Calibration with Factory Standard Filaments
All DXN Tension Meters are calibrated with laboratory
weights suspended from factory Standard nylon
monofilament sizes, as noted in the table below. Any
difference in process material size and rigidity from
the Standard materials may result in some error. For
over 95% of applications, the error is not significant
and can be ignored since readings are generally treat-
ed as production setup values or are used for
comparative purposes. In those cases where highest
accuracy is required, a correction chart showing
Readings vs. Actual Load should be made up by the
user or “Special” calibration should be specified when
an order is placed.
