5.3 Diameter and centerline distance measurements
1. Set the display at zero or at a preset value on a
reference surface (see § 6.1 and § 6.6).
or
2. Select the diameter / centerline mode by pressing the
Functions key or select this mode directly on the
touch screen.
3a. Internal diameter:
Position the measuring insert into the bore and set it
off center on the lower profile (1). Engage the
measuring force until confirmation of the measurement
by the green direction arrow and a simultaneous
acoustic signal. Move the instrument (or the part)
laterally to determine the reversal point (2). The
reversal point is stored automatically.
Note: The probing indicator (at the left side of the
digital display) must always be in the green zone when
searching for the reversal point.
4a. Move the measuring insert straight up and set it on the
upper profile (3). Engage the measuring force until
confirmation of the measurement by the green
direction arrow and a simultaneous acoustic signal.
Move the instrument (or the part) laterally to determine
the reversal point (4). The diameter value is displayed.
3b. External diameter:
Set the measuring insert off center on the lower shaft
profile (1). Engage the measuring force until
confirmation of the measurement by the green
direction arrow and a simultaneous acoustic signal.
Move the instrument (or the part) laterally to determine
the reversal point (2). It is automatically stored.
Remove the measuring insert slowly to the side, off
center.
4b. Set the measuring insert off center on the upper shaft
profile (3). Engage the measuring force until
confirmation of the measurement by the green
direction arrow and a simultaneous acoustic signal.
Move the instrument (or the part) laterally to determine
the reversal point (4). The diameter value is displayed.
5. Release the measuring insert. The centreline distance
value will be displayed during 2 seconds. Both values,
diameter and centreline distance will be stored in the
buffer (DIA and CEN).
