Hot take: I thought the Fluke 87V was overkill for our shop, but a job in Spokane changed my mind.

We had a weird, intermittent voltage drop on a G1000 power supply line that our regular meters just couldn't catch. Borrowed an 87V from another crew lead and set it to record min/max. It logged a dip to 22 volts for half a second that was killing the unit on startup. Has anyone found a more budget friendly meter that can do that kind of logging reliably?

Yeah, and to answer @paigem45, it triggers on any change outside the present reading.

What voltage triggered the min/max capture?

Honestly, that's a good question but I think everyone's missing the real issue here. The min/max capture doesn't just trigger on voltage changes, it also has a built-in timer that resets after 4 hours of stable readings. So if your system had a voltage spike at 3am and you didn't check it until 7am, the capture might have already cleared itself. Ngl, I tested this exact scenario last month and the manual doesn't mention it anywhere. Tbh, that timer feature is why I started logging my readings manually every hour instead of relying on the auto capture.
