Elog cheat discovery

I'm curious if you guys can answer this. Do your logs monitor every movement that your truck makes? Is there a maintenance mode that can be used for a repair shop? I ask because I make a 10 mile test loop around my shop, to dest drive, diagnose ect ect. Will that effect the operators hours if they get stopped? I ask this because I put about 40 miles on a customers truck last Saturday, and had it running on and off all day. He picked it up a few hours after I was done and headed to Kentucky(from upstate NY). Could that potentially cause an issue?
I've had no problems this far. Most work I do is on local run trucks, but occasionally I get an over the road unit in
Thanks
