John, this is the same calipers that I bought from Harbor Freight a couple of years ago. There is an offset of the claws that do inside measurement, when the O.D. jaws are zero. But I compensate by locking the travel down on an I.D. and measuring the claws' spacing with a micrometer. Mine also gradually began to lose its consistency, as in when drawing the jaws apart, an extra 1/4" or so adds itself to the displayed dimension. I am inexperienced with the electronic calipers and suspect a weakening battery?
