'Cuda,

I looked at the meter. From a practical standpoint, at what current reading do you determine the surface is binding? It might be a stupid question, but I would guess the extreme is obvious (ie. the current shoots up very high). Maybe the way digitals resolve, it's either binding or not. Is there any inbetween?

Please let me know how you interpret the readings on the meter to determine something is binding. I think I would like to get one of these.

Thanks,
Tom
