configured for volts or amps, but we would prefer regular meters for each,
with ranges that could be readily switched.  Several people in our
department have tried looking for such things in catalogs and on the web,
but without luck.  I volunteered to pose the question to this group.

Have you considered the possibility of using a video camera to image the
desired meter or meters and then send the signal to a projection system?
We have done this for oscilloscope displays etc and it works quite well.

for this purpose has been considered, but we would prefer a meter if such
can be found.  Thanks.
