Reply to "Another Thread About Using a Digital DC Voltmeter For Monitoring AC Track Voltage"

Leo, John; point taken on the tracking accuracy. I would expect this setup to be reasonably accurate for use in a fixed voltage command scenario in the 16-20 vac range. But in a variable voltage conventional situation I am sure the accuracy trails off below about 12 volts, as the fixed 1.4 volt loss of the bridge diode takes a larger percentage off the rectified DC voltage. We shall see.

I plan to do a little more testing nevertheless on the full range from 6 to 20 vac and just see how bad it gets. More later.
