3.3 Measuring with the Tension Meter
Inserting
:
- Push the THUMBPIECE as far as it will go in
the direction of the arrow to extend the
GUIDE ROLLERS.
- Keeping the GUIDE ROLLERS extended, bring
the instrument behind or under the filament and
move it so that the GUIDE ROLLERS contact the
PROCESS MATERIAL (see fig. 3.3).
-
Slowly release pressure on the TRIGGER until
the GUIDE ROLLERS return to their original
position. It is important to assure that the measured
material runs smoothly between the GUIDE
ROLLERS and the MEASURING ROLLER.
It is essential that the THUMBPIECE return slowly to its initial position.
Any uncontrolled snap-back may affect calibration and may also damage
the instrument.
The SCALE pointer will now show the line tension directly.
Removing
:
- Push the THUMBPIECE as far as it will go in the direction of the arrow.
- With the GUIDE ROLLERS extended, move the instrument away from the material.
- Slowly release pressure on the THUMBPIECE until the GUIDE ROLLERS return to their
original position.
It is essential that the thumbpiece return slowly to its initial position.
Any uncontrolled snap-back may affect calibration and may also damage
the instrument.
