High end Meters and burden voltage

[Freighternut]

Looks like I am going to need a good set of shunts for the Agilent 34410A.

Agilent have a reasonably accurate 0.001 ohm shunt for 0 - 30 Amps giving 1 mV per amp .

34330A Current shunt: http://www.home.agilent.com/agilent/product.jspx?nid=-536902470.536880350.00&cc=NZ&lc=eng

 I would be interested in finding a shunt more suitable for lower currents (0-10 amp) . Can anybody point me to a supplier of meter shunts preferably in the same format as the Agilent shunt (plugs directly into the meter jacks and provide banana sockets for the high current side). I have Googled this but not found anything in  this format yet.

Thanks for every bodies input it has been most interesting and informative.

Fluke has the A40 series. It might be expensive. Double check if the banana plug spacing matches your meter, I think they might be at some odd spacing.

My 34401A measured 0.86v @2.01A  and it climbed slowly as something was warming up.

That implies a poor temperature coefficient.

Assuming you measured a fairly stable constant current, did the reading also increase as it warmed up?

Didn't surprise me, copper for the internal wiring and a +ve temperature coefficient for a fuse is probably good not poor. There was 1.7W warming up something.

Yes, you'e probably right, the resistance of the fuse dominates at higher currents.
