And to make sure I'm on the same page, you are using the cheap HF Calipers, right?

Chuck,

Here's the calipers I'm using. I think yours are 4" whereas mine are 6" but it's likely they use the same circuit board inside them.
Does yours turn off if it sits with no activity after a time? Mine does and I can see that being a problem. Unlike the one Rick Sparber talked about in the PDF when mine times out and shuts off, when you turn it back on it reads as zero not where it was when the power was shut down. So the protocol is the same as what Rick wrote but the behavior is different.
