Greetings,
Two
interesting HP DMM¡¯s were the HP 3476A which could be
configured as a stand alone DMM or integrated on top of a
scope.
The
other was a unique handheld auto-ranging probe-like DMM -
the HP-970A. ?These were really kind of neat and handy.
?Unfortunately, they had a real tendency to ¡°grow
legs¡± and disappear! ?When they were a current
product, sometime in the ¡¯70¡¯s, I think they were $300 -
$400 which was more then than it is now. ?When HP
designed the 970 they must have never considered how
tempting they would be to follow people home.

Hello All,
I am doing a bit of research to
accomplish a comprehensive understanding of the DVM / DMM
technology from the late fifties and early sixties into the
90's. ?I have come up with what I think is a list
that covers the models I should be looking into. ?Are
there any more digital meters that should be
added?
