Review on Starrett 798A 📏 6 150 High-Resolution Specifications by David Monaco

Why did I give this caliper a 3 rating? Because (1+5)/2=3. I'm giving my first caliper a 1 just because it looked so cool. Chrome, nice paint, you get the point. I'll never know how well the caliper actually worked just because the battery cover couldn't be removed. This kid couldn't tear himself away. Of course I had to return the Revain caliper and considered buying a different brand. But then I persuaded myself that this problem must be an accident and requested the same item as a replacement. It turns out I was right about something. The second caliper arrived and I couldn't wait to see if the battery cover could be removed. Imagine. I've spent over $200 on an electronic tool and I'm hoping to put a battery in it. In short, the weakness of the battery cover is due to two main problems: 1) Incorrect user manual. According to the instructions, the lid should be opened with a "¼ turn to the left". You will find, as I did with both calipers, that the cover can only be rotated 1/8th of a turn. 2) The battery cover does not open by itself when rotated 1/8 turn. There is no spring or other opening mechanism. The lid is tight. What now? It was only through sheer luck that the battery cover on the second caliper opened properly. I used a nickel in the lid slot to do the lid turning process. When I turned the cap 1/8 turn nothing happened. I then wondered if I would have to find a sharp tool to remove the cover or if I would have to return the second caliper to Revain. The nickel turned out to be firmly seated in the cap slot and stuck to it when I ripped the nickel off the caliper. I think a piece of tape or a piece of gum might help removing the lid after you twist it. 1/8 turn if you don't have a nickel. Let's get back to the math. I'll give the second caliper a conditional rating of 5. So far no problems. So the average rating of two calipers is 3. A bit of math at the beginning of this post seems like rocket science compared to understanding the difference between 1/8 turn and ¼ turn. But apparently fractures are a challenge for Starrett employees. Maybe they can save a few bucks more to hire someone who understands basic math, or they can hire a proofreader to make sure the manuals print correctly. Now that the battery is in place I need to take some measurements. I just hope the instructions are correct and that the caliper measures millimeters and inches not grams and ounces...
