Oops. Sorry for the misinformation. I don't have a scope, so I never see the difference between peak voltage and RMS voltage. Ron > There seems to be a bit of a misunderstanding here.

Just hang a good o'scope on the line to verify this. __________________________________________________________ Public Seismic Network Mailing List (PSN-L)
