The OP mentioned Fluke. My Fluke does. And that gives a far more
accurate min/max than trying to read a waggling needle.

For leaving across the mains and logging its worst excurions in voltage
they are perfect, for everything else a proper analogue meter works
best.

A 'proper analogue meter' has far too high an input impedance to be of
much use these days.

And as I said, I don't use a DVM for mains. Nor would it be any good for
the job you mention as it auto powers down. You need the correct device
for that task.
