Arthur,
I could not find anywhere in the manual where it states that the meter uses the ON pulse width. I called EXTECH (mfg for this Sears multimeter) and tech support confirmed that they have no documentation stating such. I relayed my story of checking the meter against the Indy MB mechanic's duty meter and he concluded that the meter appears to be
displaying ON vs OFF as a %.
Based on this info, I would suspect that we have a few members of this forum that are running lean at 65% instead of the 45% they think they have their car set at.
Interesting...
