Mitutoyo micrometer/caliper. How do I install new glass/plastic dial cover on 6 Mitutoyo micromonitor / calipher.

Mitutoyo is a brand that produces precision measuring instruments such as micrometers, calipers, and height gauges. An error code E940 on a Mitutoyo instrument typically indicates a problem with the instrument's communication interface. This can be caused by a variety of issues, such as a problem with the instrument's cable or software, or a problem with the computer or device to which the instrument is connected.
To troubleshoot the issue, you should first check the connections between the instrument and the computer or device to ensure that they are properly connected and secure. If the connections appear to be fine, you may need to update the software on the instrument and computer or device to resolve the issue.

The nut on the end of each rod is for calibrations. On a clean flat surface check your reading at "0"and see if adjustment is needed either left or right on the nut for getting before zero or after zero readings. Adjust the nut as little as possible and re check for zero multiple times because the nut is sensitive. hope this helps.

The answers above by Kerry Littleton have nothing to do with our calipers. The answer above by Bob Pulver is well-intentioned but doesn't address the real issue.

The real issue is the ORIGIN button is little-used and a bit reluctant to "make". The solution is to use a blunt plastic probe to REALLY PUSH down the button and hold it. The caliper will reset to zero.

There should be a small set screw you can loosen by hand and adjust the face of the dial to zero with the jaws closed....this is typical of most calipers...it allows you to zero the dial on a given thickness of material and only read variations based on that thickness.
Take care.

Fully close the caliper. The pointer should be pointing about straight up or close to it. Losen the knurled screw which is located on the circumference near the bottom. Now grab the dial and turn until the zero lines up with the needle. Re-tighten the knurled screw.

The battery compartment is on the front of the instrument. The cover is round and has some symbols that resemble arrows pointing down. Slide the round cover down to access the battery.

hit the origin button the p will go away
