4.0 Quick Start Instructions
NOTE: If tension meter is equipped with a Thickness Compensator, first set up
the Compensator as indicated in section 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.

6.0 Options
6.1 High-speed Guide rollers
DX2 guide roller assemblies are rated 2000 meters/min., maximum. The following
high-speed roller assemblies are optionally available:
“K” Roller Assembly: 3,000 meters/min., maximum
“U” or “DHS” Assembly 5,000 meters/min., maximum
All high speed roller assemblies must be initially installed by the factory or an
authorized service facility.
6.2 lever assembly
On high-range instruments, the return spring force must be strong enough to bring
the outer rollers back to their original position during measurement. The average
person will find it difficult to operate the mechanism just with thumb pressure
on the Thumb Piece alone. (This is especially true with models rated 20 kg and
higher.) Adding the Lever Assembly shown here will greatly reduce the effort
required to open and close the 3-roller system. The Lever Assembly must
be installed by the factory or an authorized service facility.
