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, mark-
ing 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 number-
ing 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 Calibration Kit which includes an Alignment
Plate and two (2) special metric wrenches.
A full, detailed calibration procedure is available upon
request.
5.1 Calibration with Factory Standard Filaments
All DX2 and DXX 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 signifi-
cant and can be ignored since readings are generally
treated 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.
