Description of the return parameters
You can influence the measurement via the return parameters. The return values
are always queried after call with doProlog = True and testType = "", i.e. after the
prolog is called for each measurement series. The process then continues
according to the returned values.
Synchronous
operation axis test
Circularity test
Universal axis test
ePS_error
0 = (default setting) execute measurement
1 = Suppress execution of measurement, continue with the next
measurement series. Errors are not displayed.

2.3.4 Program example
Description
Here is a commented example program to illustrate how the prolog and epilog pro-
gram can be used to prepare the machine specifically for a certain test. The struc-
ture of the program is as follows:
Prolog for the test series:
This section of the program is only executed once at the beginning of a test series
and also on each single measurement outside a test series. This block contains
everything that has to be executed irrespective of the type of test or the axis that is
to be measured. For example, in this case G codes that are preset on the machine
via machine data (G95, DIAMON, etc.) could be deactivated, the tool could be un-
loaded, the workpiece removed, and all axes moved to a safe initial position.
