Once this reference value has been captured, the measurements can be carried out with
single or double probing.
14.4 Single & double
probing
The concept of single and double probing has been developed in order to allow the direct
measurement of certain elements and quick access to their features. While single probing
enables only height measurements in order to gain some time, double probing
is the
way to minimise the number of measurement steps and to improve cycle time. Therefore,
everything depends on the application.
Note that double probing allows you to position a reference value at levels that would be
impossible in
ST1
mode:
•
Centre of groove or rib
•
Centre of bore or axis
Other configurations are also possible (example: between two circles) but used less
frequently.
As each application is different, it is the responsibility of the user to define the most
appropriate measurement steps. In many cases, a similar result can be reached via two
measurement sequences. Only their steps are different.
In order to illustrate single and double probing, two different measurement procedures with
the same result are shown below. Note that each measurement block corresponds to one
step that has to be carried out independently of the others.
