Good point on the refresh time. I never liked tuning for a peak or
dip using a digital meter. Guess my analog brain doesn't like living in
a digital world. I've picked up old analog VTVMs for a buck or two at
hamfests and converted them to FET op amps in place of the tubes. Zero
drift/warm up and all the advantages of an analog meter that runs on a
9v battery.
If there is any interest I will write it up after I retire at the
end of this year. Looking forward to more time for what I WANT to do.

One of the characteristics I look for is response time / refresh time /
time to read. It is much easier to make adjustments that depend on
measured voltage or resistance if the meter quicks refreshes the
readings. Some multimeters, especially some of the Flukes, are
excellent in this regard. For example Fluke 170 series will detect open
and short conditions as short as 250 micro seconds. It also has a loud
beeper and I find it to be a great continuity checker.
