Test & Measurement World magazine

[Peter Orban]

The february copy of the above magazine is a special issue
devoted to automotive testing. Most of the articles contain
general information, but a one page article describes how to
diagnose and test oxigen sensors in closed loop control systems.
It also had diagrams of ox sensor waveforms of engines working
in "good" and "bad" mode.
