O2 sensor voltage output

[bruce plecan]

ref Frank Parker:

The voltage to AFR chart you show might be right
for bosch but like I said was working with GM sensors
and with them I'll stick to what I said.  BTW most of
the GNs going quick that I've heard of/seen use a 
turbolink, to record O2s, not a DVM.  Trying to read
a DVM at WOT is difficult for me.  Glancing at a 
10 LED Display isn't.  And I said as an indicator,
and to do plug cuts.  No where did I say blindly
totally rely on the 10 element, and I did explain
differences in installation, and readings.
  For a novice getting his feet wet, it is the best
cost effective manner to get in the neighborhood
that I've seen/used.  
  If during normal diving the is a sudden change in
it's display it would be an INDICATOR that there
may be a problem.
  If this is such a bad idea, what do you offer as
an alternative?.
