I have the manual but it is from an Asian company and there is very 
little to it as far as examples on how to set it up.

It doesn't have a reactance setting.  I just wasn't sure how to factor 
that in when setting the resistance or if you need to consider that 
when working on an embedded style controller.

It didn't cost that much.  Around $450.00?

The adjustables are Resistance, Current, Watts
So I think I need to set the resistance that compares with the board 
the PS ususally is plugged into.  So I just measure the resistance 
with my meter for the 12, 5, -5, 3.3VDC?  I get quite a difference.  
Is that the correct way for the resistance?  I figure you just set the 
amps to what ever the PS is rated for. Or at least close to it?  Then 
there is watts.  Do I just leave that alone or set that set the Watts 
and leave the amps at 0?

Once I find the unit online I will put a link up to it.  I have 
emailed and called the people who sold it to me but they never get 
back to me, yet.

Thanks
