[Shop-talk] Mitutoyo digital calipers not working

[Brian Kemp]

Did a duck duck go search for 500-196 CD-6CS not turning on
and got this as a top result:

writing-nerdy said:  Have you tried holding down the origin + zero 
button at the same time? But I mean if it isn't turning on I guess those 
wouldn't do anything. Don't forget you can always send it to an official 
Mitutoyo repair center for free and they'll make it good as new!

Several other options in the thread.
