Defining parameters

General
The defining parameters of the measuring cycles can be classified as follows:
● Mandatory parameters
● Auxiliary parameters
Mandatory parameters
Mandatory parameters are parameters that have to be adapted to the measuring task at
hand (for example, setpoint axis, measuring axis, etc,) before each measuring cycle call.
