Walker Cat Master O2 Tester

I've had an O2 sensor tester in a box for years. One of those things I've never used until now. A friend wants to use my Walker CleanAir Division Cat Mater O2 Tester. Trouble is I don't know how to hook it up.

It's got three wires. A ground wire, along with a yellow and red large grabber probes. I think you're suppose to disconnect the O2 sensor and insert this thing in between. I presume the red and the yellow probes complete the circuit, but I'm only guessing.

It's pretty cool. It displays cross-counts and has a lean-rich bar graph display. It takes 4 AA batteries. Looks like you can bias the reading rich or lean and observe the change in O2 sensor readings. Just wish I knew how to make it do all the neat stuff.

Does anyone have a manual for this thing?
