6.2.7 Counter function
The "Counter" test function serves to check the counting and the reference function of
incremental encoders.
The counting function can be set to Incremental signal (lines), Rotatory (angle) and Linear.
It can also be used as comparator. The interpolation, the grating period (of linear encoders), the
line count (of rotary encoders), the counting direction, etc., can be adjusted for this purpose.
Moreover, it is possible to check the function of the reference signal by counting the lines
between the reference marks (Start/stop with ref. mark).
Click the "Counter" tab to activate the "Counter" test function.
In the example, the display shows an incremental 1Vpp rotary encoder with 1000 lines and one
reference mark.
