Mirtec MV-7U Laser Height Measurment

Does anyone have a comprehensive manual or some pages on how to setup/how the laser height functions work on a Mirtec MV-7U? (Mirtec Inspector 4.5.6) Even a sentence describing what each input for these tools do would be amazing.

I FINALLY was able to figure out how to calibrate the laser offset so the dot is exactly where the cross hair is.

When using the lifted leg measurement: The only issue is now the laser is not returning consistent values. I set up a reference measurement beside the leg then put the two boxes from the lifted lead tool across the leads. Set up both boxes to have identical settings (is this necessary or just the main box?) then run the laser. Regardless of what ever filter or values i use i constantly get random measurements. Min max gives 10mm tall legs, leg counting gives anywhere from 5 to 156 legs on a 6 leg part (when no settings have changed). Sometimes the laser moves across the legs, sometimes the laser just sits in the middle of the legs...

When using the Height Checker: The measurements seem off, not reading exactly what my calipers are reading. This leads me to believe maybe i have the laser offset not calibrated correctly?

Should the laser dot be exactly where the cross hair is? How does the laser measure? Is it a single dot or is it a cone measurement? How do i get 4 corner measurements for BGAs?

Thanks all, I can post the exact steps on how i calibrated the laser dot to the cross hairs if anyone else is having trouble with that, maybe i am just dumb but that kicked my ass for like 30 minutes trying to get that to work.
