“…but if you say to clean it every time…”
My bad… I calibrate every time it comes out, even though the instructions say it’s not necessary. The clips, posts or driver terminals get cleaned when readings are odd… or inconsistent.
“..sure it is user error though”
May be, and if so… you wouldn’t be the first. No matter though, it’s appreciated that you post back when you’re able so if others are pondering similar events they’ll know their not alone… and you might also find something aside from user error that could be helpful. Thanks
