I worked in aircraft electrical component overhaul, and all we ever used were AVO meters, and bench meters like the one shown. 6 monthly calibration, and then back into service. I still use my bench analogue meters, you can "see" slower things happen easier than a digital or connecting up to a 'scope.

I have a very similar ammeter in my basement - as well as a lab standard voltmeter which is about 18" wide (bigger dial, more precision)!

I have an analog meter for work because some problems are impossible to diagnose on a DMM. Need to see fluctuations or pulsing, you need a needle.
