In the mid-1990s, if you walked into a RadioShack with $29.99 in your pocket, you walked out with the 22-805. Officially dubbed the 24-Range Digital Multimeter, it was the perfect storm of utility and affordability. It wasn’t a Fluke. It wasn’t a high-end Beckman. It was the people’s multimeter—the gateway drug for garage tinkerers, car audio installers, and hobbyist robot-builders.
