voltmeters don't output anything. They should be fine measuring solid
state.

DMMs and VOMs give different readings in certain circumstances (see
Ralph's post). In GB (at least) for a long time the service manuals for
decent gear would provide expected voltage readings for 20k OpV analogue
meters, the AV0 model 8 specifically IIRC, which saved the technician the
extra bother of scratching his head when checking hi-z parts of a circuit.

For amusement I fetched the Avo Model 7 that I inherited from my father
(goodness knows when he got it!). The plate on the back specifies 1.5V
cell for 1M, 2x4.5 for 1M, and external voltage sources for 10m and
40M ranges.

It also weighs 5lb (2+kg). I guess in those days servicemen were MEN!
