Re: testing O2 sensor

["Bruce Plecan" <nacelp@bright.net>]

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...
