How to ensure correct measurement

NOTE
Regular inspection of the stylus systems is required to ensure correct
workpiece measurement.
– If particles adhere to the stylus tip or a lubricating film has formed,
the stylus tip must be cleaned.
– When the stylus has become damaged, it must be replaced.
– The adapter plate must likewise be free of impurities and must be
cleaned, if necessary.

Probing procedure

What you should know!
The type of probing depends on the measuring job and the required
number of measuring points. Position measurement requires only one or
more discrete-point probing actions. Multipoint probing or scanning can
be used when determining dimensions. Scanning must be used for form
measurements.
NOTE
The following conditions must be fulfilled for probing: These conditions
depend on the probing system. See brochure »Sensors«.
Probing conditions
– Constant probing speed.
– Minimum distance to the contact point.
A minimum distance is required to reach the probing speed. The
minimum distance should be 2 to 4 mm. In case of smaller dis-
tances, the probing time increases.
Probing speed
Probing should be carried out at constant travel speed.
The travel speed depends on the deflection of the joystick. At the begin-
ning and end of the deflection range, the travel speed is proportional to
the amount of deflection. The travel speed between the beginning and
the end is constant. This speed corresponds to the probing speed.
