Compared Fluke and Klein multimeters on an A320 APU fault last week
Honestly, I always used Fluke meters for line work, but my new shop has a bunch of Klein MM700s. Tried using the Klein to chase down a generator control unit fault on an A320 APU last Tuesday. It worked fine for basic voltage checks but the auto-ranging lagged hard when I needed quick readings on the frequency output. Swapped to the Fluke 87V and caught the glitch in under 2 minutes. The Klein is probably fine for general use but for bus power troubleshooting, the Fluke is way snappier. Anyone else stick with one brand for complex stuff?

The MM700 has a slower sampling rate on AC frequency than people realize. I looked at the specs after a similar issue on a 737. Its 40ms response time is fine for motors but too slow for generator outputs that fluctuate quick.
