Yea, IMO the UNI-T is a better meter for the price, Dave. You have a good one there. 

After sending my last post I do recall hearing "daisy chain" in a Pink Floyd song. I know the term is out there on both sides of the pond (referring to a chain of flowers). Ken might have been asking why I would use that term when referring to two electric devices. Its just another term meaning 'in series'.  One hooked together after another. 

Ken, you could have one meter reading current (amps) and a second meter reading the voltage. Or one reading volts, and a second reading Freq/Htz, etc...

Or, if you're some nutter who happens to own like 6 meters. You do it just because you can! *maniacal laughter*
