How ?
If I want to know the peak voltage I leave the meter connected go off
have a cup of tea and when I come back the peak, average, maxium can be
called up,
(depending on meter) without me having to sit there for seconds,
minutes, hours or days staring at a needle with a mirror behind it.

Slight misunderstanding here. I'm talking of the kind of tweaking and
peaking us radio hams have to do when tuning intermediate frequency
stages of amplifiers. The effect is much more easily seen with an
analogue meter.

yes I can understand how flicking needles can make things easiier for some.
But the majoroty I think are better off with a DMM, some of those have anolgue displays if you really need it.
Are they many radios hams left, our rad-soc in the uni disapeared 20 years ago.
