Mitutoyo E-05 error fixed!

We received this Mitutoyo 1-2" digital micrometer, .00005" 0.001mm today, and were faced with an E-05 error on the panel. So what do I do? Try to return it? Haggle for a refund? Of course not! Let's rip it open and see what makes it tick!
What follows is part adventure, part horror, but as always, the hero wins and the day is saved!

I loosened the left screw 1/16 of an inch and it removed the error. I didn't touch the right screw. Thank you for the useful video.

Hey Mate what awesome video when I was about 8 years old I took apart My old mans short wave radio Because tuner knob was not right!!!! needless to say I kind of broke the darn thing , Now I am 53 and there are very few things I cannot fix .... your video saved me time and effort . I bought 1-2 Mic for 40.00 dollars on craigslist . took maybe 45 minute after seeing your video to get working. thanks again

[@JBFromOZ]

Gotta love the hive-mind for shared knowledge! Glad it helped mate

[@artemisargent8623]

The reason why it isn't ratcheting is that it's a friction thimble, as in it uses friction of the spring to limit torque on the measuring surfaces

[@JBFromOZ]

Excellent

[@billbrennan8405]

Hello nice job getting it apart without killing it. #1 what your mic has is a friction thimble , they have one that looks similar But has a ratchet mechanism inside and i rather prefer that to the slip sleeve you have. #2 the flashing “P” is a preset function which allows one to set a origin preset numeric value. But you must hold the button in till the cursers appear under each display digit. CAUTION the first space will change the display from positive to minus. Lets say you have a 1.500 gage block you can set the origin value to 1.500 rather than 1.000 . Only one thing if you need to reset the origin you will need the 1.500 block. We should all keep in mind the accuracy of measuring instruments still rely on the accuracy of the ground mic screw thread, its only converting the rotation to a rotary counter for digital display which is must faster to read the value. People its not magic, the tools suffer the same damage when dropped or misused . Always treat them with great respect & care & ( NEVER LEND THEM OUT ).

[@JBFromOZ]

thanks for updating us on the functions here mate, all very welcomed cheers mate

[@nka1383]

how did you disassemble this micrometer? you didn't show it

[@Xynudu]

Great job and video. I really enjoy this type of stuff as it takes us out of our comfort zone into uncharted waters. Cheers Rob

[@JBFromOZ]

Thanks mate! Really appreciated :-) I'm fighting the KZbin 1,000 subscribers 4,000 hours battle this month it's awesome to have feedback like this to keep me going! Im a big fan of your channel and have learned much from watching cheers

[@MarcelDiane]

Good job fixing it, I have a propensity to take things apart just to see how it works.Im not always successful at putting it back together without extra parts.

[@JBFromOZ]

G'day Marcel! It appears I have been very lucky with both the Fowler Verdict test indicator and the Mitutoyo mics. I have previously failed at many attempts too ;-)

[@samrodian919]

Nice vid sir, I have an older one inch digital and it does indeed have a ratchet mechanism, which is very very easy to fuck up the spring! Don't take apart unless you are prepared to get a new one from Mitutoyo lol I have just got a standard 0-1" tenths mic and it has the same spring arrangement as yours has, having no clicks but relying on the friction of the spring unwinding to give the same moment of force to close the faces of the spindle and anvil.

[@JBFromOZ]

Yes indeed! Attempting to open up a set of delicate instruments like these is always a risk if the first time. This is one reason I try to capture my folly for others to learn before they also follow ;-)

[@johnsherborne3245]

I’m just reassembling my digimatic, the rotor of the encoder is keyed to the spindle with a pointed grub screw, which is in turn locked with a second screw in the same hole. Took me a while to work out but really helped once I knew. What surprised me was how simple the design is and how well it works.

[@JBFromOZ]

Yeah awesome! Glad you got yours sorted

[@littlejackalo5326]

​@@JBFromOZFYI you have a friction thimble, not a ratchet thimble. Two different things. It's not supposed to "ratchet" or "click."

[@houseofbrokendobbsthings5537]

Almost had one bought - good overview. Seller contacted me and said it got wonky after he put in a battery. Almost worth taking a shot with it.

[@JBFromOZ]

yeah i have had a couple of "re-visits" of the E05, but a quick wiggle and back to good again since...

[@Lestat103]

You don't hear ratcheting clicks with yours because of that wire spring. Other similar Mitutoyos will be fitted with a flat sheet metal spring instead, which is riding on an internal ratcheting wheel inside the barrel. Those are the ones that click.

[@JBFromOZ]

I have a follow up video which shows both types of mechanism!, I prefer the metal spring one, it feels more "positive", the wire spring seems to loosen up over time

[@465maltbie]

When you look at the options for Micrometers, this is called a friction thimble. the one you prefer is a ratchet thimble. Thanks for sharing your video.

[@JBFromOZ]

indeed!, here is my video illustrating the two variants, thanks heaps for watching kzbin.info/www/bejne/p3unoZuQocaNfK8

[@manoluisi4281]

I can't get the little black steel cylinder that guides the measuring rod back on without removing the connector pin holder. Have you removed it?

[@JBFromOZ]

It was a long time ago, I’m sorry I don’t recall

[@rafavisca8040]

Greetings from Spain, thank you very much for your video; I could take a picture of the flex connector, in the video I can not distinguish the connections well, I need it to repair. Thank you. Sorry for my English, I use a translator. Moments of his video that is almost appreciated, what I ask: 3:56, 3:45, 3:55, 4:01. regards

[@JBFromOZ]

I will try to get some better pictures for you

[@rafavisca8040]

@@JBFromOZGracias por tu ayuda.

[@oscaritocortes6223]

El mio es el modelo de 0-1 se atora el tambor, lo limpio y sigue estando duro al girarlo

[@eeclarkutube]

How do you turn this bugger off? Referring to the Mitutoyo.

[@JBFromOZ]

From memory it turns the display off after idling for some time, (this helps retain position so it doesn’t lose calibration between uses) it remains on low draw power to hold position though, so batteries do drain over time

[@MrWellboat]

You need to wash your hands with soap, especially before eating and precision work! 😂

[@JBFromOZ]

I should’ve listened to what my mother told me when I was growing up…

[@leonardosantis4521]

Muy bueno me sirvio para reparar el mio (y)

[@JBFromOZ]

Estoy tan feliz que ayudó. Gracias por hacérmelo saber

[@charlesbennett2586]

Useless Starts off with it disassembled - lots of mumbling, ...presto it's reassembled (skipped those steps too)

[@wesc23]

Yeah, pretty much worthless video. can't find er-05 fix elsewhere on web.

[@larry527az3]

I agree, though some of the shots helped me with re-assembly of mine. Would have been great to see the steps involved with disassembly and equally the re-assembly of the mic. I'm still struggling with a stiff thimble and haven't figured out the purpose of the ratchet portion, my ratchet thimble just free spins when closing the mic, seems to work okay when opening it though.

[@MrWellboat]

С такими грязными руками нельзя выполнять работы с микрометрами! После этой грязи они будут показывать всё, что угодно, кроме правильных и точных показаний!

My hands are dirty but my parts are clean ;-)
