Is there any reason a fluke RMS meter would be far off. Vinnie has one of these and now with the combined issues on the scope would RMS meter be less quess work?
In regards to the sine square wave combination would that be better or worst than a pure sine or square wave for filament supplies?
This is on my to do list now. Would be nice to get rid of 10,000 to 20,000 electro caps on current filament supplies.
Thanks Tom

Someone posted that the the fluke gets flaky on voltage past a frequency of 1k. Apparently that is all it is designed for.
I found on my Fluke 87 that if I use a certain range, its pretty close.
Automatic range will bounce back all sorts of voltages depending on which range scale the reading falls on. I can back check this and tell you which scale. You'll see it right away if you try it, results will be around 12v on one scale and jump 20 volts on another.
Whats weird, is the the freq (Hz) on the 87 will give the correct frequency.

thanks for the suggestion. I will have to give that a try.
Good catch Vinnie!!! Looked up my 87 specs and it is not happy from 5k to 20k. Keep us posted this is what DIY is all about.
Thanks Tom
