Answer of your question is that i have Mitutoyo roundness tester(2nd Hand) model no Ra114,
From last three to four years it was just placed in a corner and in the mean time the catalogue was also missed. Now i need to start but after connecting all the accessories, its LCD was not glowing.
As i dont have user manual so i m unable to start.
Can u provide me some technical tips as well as its manual in PDF form.
