Got me a Mititoyo 6 " caliper way back when. I have changed out the battery several times without issue. This time when I changed the battery when I turn it on I get a negative measurement of -1.1280". If I zero it out and press the abs button it sets to zero. When I shut it off and restart it I get the same thing, oh and once in a while it will bounce around between -1.128 to 0.0050. What do you guys think, is it fried or what. I don't know.
