Proceq Equotip 550 Operating Instructions Manual page 21

NOTE! In case the probe connector is in an inconvenient
position, release the set screw. Ensure that the springs in
the mechanism do not get lost. Turn the mechanism into a
convenient position, aligning the set screw with the guide
channel. Lock the set screw so that the probe holder will still
slide up and down without rubbing on the set screw.
3.3.2.6 Considerations
• When measuring cylindrical samples with adapters Z4 or Z4+28, make
sure, the sample is not twisted on the clamp support. This is best
ensured when the back part of the clamp rests on a table and only the
sample support of the clamp sticks out over the table's edge.
• When applying the load, slowly squeeze the leavers and allow the
sample to adjust to the support. During the measurement, do not
touch the sample, if possible. When releasing, grab the sample again.
• Whenever the sample geometry (i.e. the wall thickness) allows it, free-
hand measurements usually offer better measuring performance. This
applies particularly to measurements on cylinders.
• For small diameter rods (or stiff enough pipes), the V-notch clamp
adapter Z2 has been designed. When installing the Z2 support ensure
that the centre of the V-notch is centred underneath the probe holder.

3.3.2.7 Installation of Standard Foot or Tripod
The round standard foot permits meas-
urements on test objects that are only
accessible from one side, such as large
metal sheets. The tripod is used when
the flat foot cannot be placed on the test
piece without wiggling.
1. The diamond indenter remains
mounted.
2. Install the foot on the probe.
3.3.2.8 Installing the Special Foot
Two special feet extend the Portable Rockwell application range to cy-
lindrical test pieces.
1. The diamond indenter remains
mounted.
2. Install the foot on the probe.
3. Place the foot on the test piece and
release the set screw on the foot.
Then press down the probe onto the
test piece and lock the set screw.
