QUICK START INSTRUCTIONS
NOTE:
If tension meter is equipped with a Thickness
Compensator, first set up Compensator as indicated in
3.0.
1. Prior to engaging the material under test, part the
3-roller system by pushing and holding the Thumb
Piece forward.
2. Keeping the outer rollers extended, bring the
instrument behind or under the filament and move
it so that the Filament Guide bars contact the
process material.
3. Slowly release pressure on the Thumb Piece until
the outer rollers return to their original position.
This will automatically direct the material into the
guide roller grooves.
4. The scale pointer will show line tension directly in
grams or kilograms.
5. To remove the instrument from the process
material, push the Thumb Piece forward again to
open the 3-roller system. With the outer rollers
extended, move the instrument away from the
material.
6. Remove the instrument and SLOWLY release
pressure on the Thumb Piece, allowing the outer
rollers to return to their original position.
CAUTION: Do not let the Thumb Piece snap
back as this may affect calibration and also
damage the instrument.

5.2 Special Calibration
Special Calibration is optionally available for a specific
material type and size so long as the material fits the
mechanical limits and range of the instrument. The
customer must supply a 10-ft sample (3 meters) of the
material. Such calibration can be performed with or
without using the Thickness Compensator if one has
been provided with the instrument. If not specified,
the calibration facility will use its best judgment.
Note:
Special calibration is available for a single
sample only.
5.3 NIST Calibration
While all DXN instruments are furnished with a
Calibration Certificate which certifies that they have
been calibrated in accordance with factory procedures
and were found to meet all published accuracy specifi-
cations, such calibrations do not fulfill ISO-9000
requirements since no record of measured values are
kept or are submitted. Where ISO-9000 requirements
are to be met, NIST calibration is optionally available
but must be specified at time of order placement or
after repair.
