4.3.4 Adjusting probe clearance
The test heads are adjusted to the
nominal diameter (clear opening) of
the protective nozzles
by a hand wheel.
A standstill detection facility installed in the adjusting device prevents ac-
tuation until the rotating head has come to a standstill.
The adjustment scale is calibrated in such a matter that a safety distance
of 0.2 mm is maintained between the protective nozzle and test head
when adjusting to the nominal diameter over the entire adjustment range.
