guide rollers.
- Capture the process material with the filament guide (see fig. 3.5.2).
- Slowly release pressure on the thumbpiece until the guide rollers return to their
original positions.
It is important to assure that the process 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.
