6.2 Adjusting the handle
The handle is set so that the electrical connection is made before the measurement is started,
just before the handle is fully depressed.
The handle does not normally need to be adjusted, but can be adjusted if necessary.
Method:
Attention!
Do not unscrew the adjusting screw too far, because the handle
will not be able to fully close (there will be a leak along the
plunger).
1. Unscrew the locking nut (pos. 93-2),
2. Adjust the adjusting screw (pos. 93-1) (to the left advances the moment and to the right
delays the moment),
3. Tighten the locking nut.
