Reply to "Voltage display"

Well, I ordered one of each of the ones I posted, but the results are less than stellar with a chopped waveform transformer. On the bright side, they came quickly.

I suspect those kind of results aren't going to please many people.  There is a 75 ohm resistor across the output for a small load, this prevents the stray AC from giving us false readings.

The meter on the right is a Fluke 8012A True-RMS meter, the meter on the left is the one I described in a post above.  I don't expect the ammeter to do any better with a chopped waveform, so these aren't actually ready for any layout using one of the many chopped waveform transformers.

The meter looks pretty good with a pure sine wave from the 1033!

Hot stuff, let's try a Z750.  UGLY, massive errors across the whole band!
