O2 sensor checking (more)

OK,

I did the check in the Bentley manual on the O2 sensor in my '90 325iC
(4-wire O2 sensor) with a friends DVOM over the weekend.  Now, the 
manaul doesn't say what values of voltage I should read.  It only says
to use the 0 - 1 volt range.  Well, we were getting readings around
10 - 20 mv.  This seems awfully low to me.  If the "standard output"
is supposed to be .45 volts, then is this telling me my O2 sensor
is shot?

          Thanks!
              Larry.
