3.1.3 UCI Testing Procedure
1. Place the probe on the sample to
test. The probe must be perpen-
dicular to the surface (± 5°). The
special foot can be used to increase
repeatability and reduce distor-
tion of the results, see chapter “14.
Ordering Information”.
2. Press the probe slowly but firmly
against the surface until the se-
lected measuring force is reached.
The instrument will indicate when to
release the probe with an on-screen
prompt and audible sound.
3. Release the probe from the mate-
rial. It is important to remove the
probe completely from the test
object. Otherwise the results can be
biased.

NOTE! A warning will be shown if the user applied too much
load when pressing the probe against the surface. Please avoid
frequent overloading, as this could seriously damage the probe.
3.1.2 Portable Rockwell Testing Procedure
1. Place the probe on the sample to
test. For flat surfaces the standard
foot is most suitable. For cylindrical
objects it is recommended to use
one of the special feet. For locations
difficult to access a tripod foot can
be used. See chapter “14. Ordering
Information” for more details.
2. Press the probe slowly but firmly
against the surface to perform the
measurement. Suppress vibrations
as much as possible, and follow the
instructions on the screen.
3. Release the probe when the instru-
ment says so. Again, this movement
has to be done in a controlled man-
ner. If the probe is released too fast,
a warning will be shown and the
measurement should be repeated.
