3.0 QUICK START INSTRUCTIONS
1. Prior to engaging the material under test, part the 3-roller system by pressing
and holding the Trigger.
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 Trigger 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 Trigger 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 Trigger, allowing the
outer rollers to return to their original position.
CAUTION. Do not let the Trigger snap back as this may affect calibration and also
damage the instrument.
