I have tried curve tracer (luky_z) and npn mesure fine (maybe)
PNP are way out with hfe going up to 760 which is way out of speck as 680 is max for for 40 type

This with 100% original fairchild from fairchild direct

So I am thinking that maybe sometink wrong with intelligent, not so much, curve tracer (mine at least)
Still get same nice curves and maybe to group togheter is quite handy.
But as a lab instrument is more on toy category as manual to correct error is praticaly none existant.

I am waiting for batch as suplied on Paradise parts to try and mesure those new batches and confirm that my curve tracer has ofset error on PNP.

In the mean time if Frans could post details of his set up and mesurament parameters this would be greatley apreciated
