The following applies if more than 1 function is activated:
The values for all functions cannot be read until each activated func-
tion has been terminated and this has been confirmed in the corre-
sponding status bit (ZSW.0/.1/.2/.3 ”0” signal again).
Find reference marker
Up to 4 reference markers can be found. Reference markers can also
be skipped (e.g. find reference markers 1 and 3).
Equivalent zero mark

Flying measurement
The positive and negative edge can be activated simultaneously.
The measuring probe signal is recognized depending on the direction.
The values are read out in succession.
