Has anyone every had a digital caliper fail to give consistent readings?
I'm starting to suspect mine. As a security check I'm re-zeroing before each measurement now. But I wonder if erratic numbers is more likely the calipers versus the dies and machine... |

Nothing wrong with the re-zero you are doing, but you will want at least one other point greater than zero to check the scale.
For example, a gage block, gage pin, or some known reference. As a last resort, you can select a bullet when you are desperate. For Example.... A 30 cal bullet should read close to .308 +/-.001 or you should worry about the caliper. Calipers are not expensive, so if they quit on you it shouldn't break your bank to replace them. |
| If it`s a cheap one (uder$60) that`s more then likely the problem. I know because I have one ($29). My machinest friend has one that`s old & tells the truth everytime. Corse, he paid over $100 for it 18 years ago. Yes he does put new batteries in it once & awhile. |
