They say (not sure who "they" are) there are no dumb questions, so here goes-- I recently came into possession of a Helios 4" dial caliper, 0-100-0 dial face. I can't find a model number on it. How does one go about adjusting the dial face/pointer such that it is in the "12 o'clock position" when reading zero?? Right now, it is "clocked" at about the 10 o'clock position, and well zeroed there. I believe the dial face is frozen/stuck, as I cannot get it to rotate. There is a small knurled thumbscrew that protrudes from the REAR of the dial, not sure what it's function is. Could it possibly be the dial lock? It turns freely, I can easily screw it in/out. The dial face will not move regardless of it's position. I am familiar with Mitutoyo dial calipers, and there is a similar thumbscrew/clamp to lock the dial but it is located on the outer periphery of the dial. At any rate, I realize once the Helios dial can be rotated to 12 o'clock, the rack/gear/pointer relationship will have to be adjusted as well to re-zero it. There is no tool provided with the Helios (the Mitutoyo does have one in it's case) so not sure how this would be accomplished on the Helios. Use the Mitutoyo tool, or make something similar?
Sorry for the long-winded (and probably dumb as well) questions, but I need some help with this. This is the first Helios caliper I have owned. And yes, I realize the simplest thing is to just LEAVE the dial where it is
