	Some meters have such a slow sampling rate that the average looks
like no O2
	counts.  Then if trying A/C they can do the RMS (?) thing and again
look
	wrong.  Know your meter, be one with meter, good Karma.  Really best
to use
	scanner, and see O2 Counts or at least a handheld scope (MCM had
them for
	$199).  They have and even better one now that's dual trace for
$299,
	FWIW...
