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.
--------------------------------------
For peaking adjustments, even some of the cheap(er), slower DMMs like the
Radio Shack I mentioned have a relative level scale - a row of dots below
the numbers - that moves according to changes in the voltage or current
level. That scale works quite fast to show a peak or dip even though the
numeric display takes a few seconds to update. It's something I recommend
one look for if they are going to rely on only their DMM for making
adjustments.
