[time-nuts] Need volt-nuts help

Hey Ed, thanks for the tips. The DC-200 has a quite different meter  
system based on the pix of the DC-150 you linked to. I did find a  
manual for sale for a model DC-200AR, and have inquired if the 200AR  
is at all similar to the 200C. If it is, I'm good to go.

Thanks,
Dick Moore
