Help! how do you use an engine analyzer

Hiya folks,

Well Taildragging came home with a new toy today!!!
Problems is not sure how to use, it was a freebie so theres no instruction booklet.

Would appreciate any info on how to use this.
Like why are there 2 inductive clamps and what are the black, orange & green things for?

Here's a couple of pics of what it looks like.

Thanks

Daisy

 

Here's a closer one of the dials

i have the instruction manual for a similar unit,which i no longer have.it would be easier for me to send you that than try to explain all the functions and gizmos on your machine-george

 

That would be great if you could do that.
I'll send you a PM
Thanks
