Ask and ye shall receive; Bob sent me a vi that lets me log current from the 3478A. Now perhaps I should fiddle with the counter on that 3497A and see about full on automation of dP/dQ curves*

*or log mA in Labview and flow with the CF633 and merge the logs manually
Lovely. Thank you pHaestus.

A little better than anticipated but very restrictive. (head loss, head loss... )I take it that the maximum flowrate point is what was achievable.
Rue-ing the mistake that forced me to block a quarter of the tunnels. Probably wouldn't make too much difference on the small die though.
Very very happy to have a baseline. I will return to my numbers in a few days after the holidays, so some better comparisons can be done, but at this point the 0.182C/W@2.73lpm number stands.
Hard to quantify the temperature compression. We wait for your diesim setup.
Have you decided on a die size, material, probe placement?

Thanks heaps
