Rant: I chose a multimeter with analog display over digital

Ngl, everyone at the hangar in Phoenix laughed when I brought in an analog Fluke 27 for line work. But after 6 months troubleshooting interference in a Gulfstream, that needle helped me catch a 5-volt drop that a digital readout would have smoothed over. Anyone else stick with old school gear for signal work?

Used to be all digital all the way, thought analog was just nostalgia bait. But your Gulfstream story actually makes a ton of sense. Digital displays average things out, so you miss those tiny fluctuations that a needle can show in real time. Never really thought about how a digital readout can hide a slow drift or a quick drop like that. Can't argue with a 5 volt catch on a bird like that, that's a serious win for the old school way. Might have to dig out my dad's old Simpson 260 and give it a shot on some signal work. Makes me wonder how many other guys are running analog on the quiet.

Man I gotta push back a little on this one. Yeah the Gulfstream story is cool and all but people act like digital is just a random number generator these days. A good fluke meter updates fast enough to catch a dip if you know what you're looking at. Plus those old Simpson meters drift like crazy if you drop them or they sit in a hot truck. I've seen guys chase their tails for hours on a bad ground because their "trusty" analog meter was reading a couple volts high from a worn out battery.
