Newbie halscope question

I just started using halscope, and would like to be sure how units from halscope are translated in real world for example pid error from encoder, if I have setup scale of signal on 200m/div and error reading curve is between two horizontal lines that means how big error is in real world?
I,m using metric units (mm).

OK, this is one of the cases where halscope units get messy. The 200m is 200-milli times
your user unit, which is mm. So, that is 200 milli - milli-meters, or 200 um between graticule
lines on the display.
