I've had my Mitutoyo 505-626 6" dial caliper for almost 40 years now and just discovered the depth measurement end of the rack cover has gone out of calibration by about.012". In other words, when the jaws are completely closed, the depth measuring end is below flush by about that amount. I have dropped the caliper only twice in all that time, but that must be the issue. I don't see any way to re-position this part, and really don't want to take the caliper apart without some information on how to proceed. Thanks in advance for any help you can pass along.
