Looking for a manual for the tenma model 72-540 signal tracer/inj

[DTiernan]

Hi,
I just bought a Tenma 72-540 signal tracer/injector. It is missing a manual and the probe. I would like to make one for it but not sure of the original probe/probes it came with. Any help would be appreciated.

I realize this is years later, but I am in the same boat. I need to build a probe for this unit. I'm finding it very difficult to find info about doing this online which is surprising to me!
