My Mitutoyo Digimatic caliper is refusing to work and says "Err 05". Would anyone have any idea what this may mean?

Ayup..it cant read the scale any longer. Its the equivelent of the Microsoft Blue Screen of Death. Ive got 4 Mitys in the junk box that all have that error. Means the circuit board is toast and it costs almost $60 for Mity to replace it, based on 2 estimates from Mity in Los…

As of October 2026, Mitutoyo's user's manuals for several ABS Digimatic calipers show an "Err-5" display in their error tables. In manual 99MAD027A (ABS Digimatic Caliper; models including 500-150-30 to 500-197-30 and the 550-/551- nib-jaw types), section 11 "Errors and Countermeasures" shows "Err-5" under "Other errors" with the instruction: "If the error shown in the figure occurs, set the origin again." Manuals 99MAD030A and 99MAD031A (IP67 ABS Coolant Proof Calipers) show "Err-5" alongside "Err--E", "Err-51", "Err-52" and "Err-53" under the same heading and the same instruction. These manuals list a separate minimum-digit "E" display, which "appears if the surface of the scale is dirty to an immeasurable degree", and 99MAD027A gives the maximum response speed as "No limit (no miscount caused by speed)". The thread is from 2008 and does not name the caliper's model, so it may not be one of the models these manuals cover. On counterfeits, Mitutoyo America says counterfeit products "may cause measurement error" and asks buyers to "contact authorized Mitutoyo America distributors to purchase Mitutoyo products."

On the older ones, it means you overrode its ability to keep up with movement of the slide. Either you moved the slide too fast, or it has water, oil, or dirt on it. Reset by turning it off and on. Clean the scale first and wipe with a VERY lightly oiled rag.
But that reading looked like this: E--e5. If yours says Err 05, it's probably a newer one. In that case, call Mitutoyo to find out: 1--888-648-
8869.-- Ed Huntress
I think that it is E--e5. I was quoting by memory. I will try to clean it.

I've got a Mitutoyo scale and I can reproduce the error quite easily by holding the scale in my sweaty hand for a minute or so then running the reader head across that section, after allowing to dry and a reset it will work fine again. Not saying yours aren't dead, just it may be a cleaning issue in some cases.
I had this problem on a 24" Heigth Gage. There is a plug in connector that can loosen up and the pulses don't read properly. Open it up and check the connections.
Too bad.
Are the "new mitutoyo calipers" sold on ebay, counterfeit?
A lot of it stems from folks not being able to read analog tools anymore.
Need proof- hand a college kid a non-digital caliper or mic and enjoy the bewildered look on his face
Day is deader den da cow what mah hamburger just now came from.
Trust me..as cheap and as motivated to scrounge/fix stuff up..when I say they are dead....day is history.

No idea. It should be noted that even the Chicom imports are just as accurate as the Mits in the vast majority of cases. They simply just dont last as long oftentimes.
Yeah..Ive got drawers filled with Miti, NSK, Fowler, Federal and so forth. And use decent cheap chicom stuff for most of the dirty nasty jobs, like leaving them laying on the carraige of the lathe while cutting chips, with flood coolant.

Just like I used to love when people asked my if they could borrow my HP calculator with RPN and they spent time looking for the = key or if they got that far looking for the "off" button as it had an"on" button, maybe like Windows with "Start" but no "Stop". I got my HP returned once after losing it and went to thank the guys that turned it in, they said "nice calculator" and would have kept it if they could figure out how to use it.
Gunner, not to dispute your death certificates, but I have resurrected a gang on Mitutoyo (and other electronic) calipers, that "die". and I havefound that a number of them gave up because of damage, chips, small specks of dirt, swarf, attached to the reader, though the scale in the beam remained ok.
Repair involved full disassembly, cleaning the pickup thoroughly.

Coin cell (battery) low?
Dirty scale (just wipe it clean along the whole length).
Need to remove the coin cell, turn it "on" to discharge it totally, let it sit for a few minutes, then re-insert the (fresh) coin cell. Sometimes, bouncing contacts when installing the battery can confuse the tiny little CPU in the thing and letting it go to sleep to forget what had happened is the easiest way to clear it.
I don't have a manual with mine, or I would try looking up the error code. If you have the manual for yours -- you could try that.
Good Luck, DoN.
I ought to dig them out and send em to you. Fixem all and send me back half, you keep half.

definitely not. I tried a new battery.
does not help
I bought this caliper 14 years ago at a pawn shop in Oklahoma. No manual either.
Think you got your moneys worth yet?

Most definitely. It served me faithfully for these years, and cost just $20.
Then put it in a nice little shadowbox, drape it in black crepe and put a RIP-2008 plate on it, and get another one. They are cheap and frankly ...disposable.

I will keep using it, for wood and stuff, where I do not need the readout.

You mean, like, measure it with a caliper, mark it off with a crayon and cut it off with a chain saw? sorry, couldn't resist.......;>)
