Inserting the material to be measured
:
- Push the thumbpiece in the direction of the arrow into its threading position 1
(Fig 3.5.3a) until the outer guide rollers extend beyond the filament guide.
- Position the material to be measured into the tension meter in such a way that it
contacts the Filamente guide and passes between the outer rollers and the middle
measuring roller (see fig. 3.5.3a).
-
Slowly
move the thumbpiece back into the adjustment position (Fig. 3.5.3b).
It is important to ensure that the material to be measured runs smoothly between the
measuring roller and the guide rollers.
- Push the thumbpiece into the measuring position (2) (Fig 3.5.3b).
- The display shows the measured tension value.
If the thumbpiece is not in position 2, a corresponding
message is issued on the display. If the thumbpiece is
not locked, faulty measurements might result.
