I swore by my old Fluke meter until a weird fridge job in Tacoma last Thursday

Was diagnosing a weird intermittent compressor fault on a 12 year old Sub-Zero, and my trusty Fluke 87V just wasn't catching the brief voltage drop. A guy at the supply house loaned me a newer model with a min/max record function, and it caught a dip to 103V I would have totally missed. Anyone have a go-to tool for catching those ghost electrical gremlins?

Wait, you were getting a voltage drop down to 103? That's not just a fridge problem, that's a whole house wiring issue. That's a serious sag. Did you check if it was just that circuit or the main service? A drop that low could fry more than just a compressor.

Could just be a bad meter reading.

That min/max function sounds like a lifesaver for those quick drops. Did the new meter show how long the voltage stayed that low, or was it just a split-second blip? I've heard some guys use data logging meters for jobs like that.
