On our equipment I purchased two Radio Shack panel mount voltmeters. They come with a 15K resistor and with the resistor in series they are 15 volt full scale. A little calculation shows that the meters are a 1 mA movement. So I put the meters in a diode full wave bridge and upped the resistor on one with a bunch of 1 Meg resistors so it would read out 15 KV full scale, and put a shunt across the other meter so it reads out 30 mA full scale (when I had it on one neon sign transformer). I put a diode across each meter to protect it from transients, and took the 1.15:1 RMS vs average voltage ratio into account, since these meters will be reading average instead of RMS.
Works great, and gives instaneous voltage and current readouts. Marshall James Osbourne, Holmes wrote: > HI Ivan, > > I measured the secondary a couple of times.
