When I was a young test engineer in the early ’90s, I learned a lesson about the use of an analog meter from an old POS (plain old telephone system) technician. Our lab received a new noise meter. The meter had a digital display and a mirrored analog meter complete with a black needle. I was going on about why can’t we get modern gear. The old tech was tired of me ranting, so he proceeded to explain to me why the analog meter was useful. He explained that you don’t have to read the scale to know what value the needle is indicating, you just have to note the position of the needle. If the gear you’re testing is across the room from you and you can’t see to read the digital display, you can look at the analog meter movement and tell where you are. I used this concept to teach my kids how to tell time on an analog clock. The position of the minute hand is key to breaking an hour into quarters. It makes visualizing the passage of time easier than when using a digital clock.
