That is a pretty amazing instrument. Appearantly the only thing
Tegam changed in the new B version was the box, shaving a some
kilos of the weight, as far as I can tell, everything else in
the manual is identical up to and including the errors in the final
I find somewhat ironic that my HP3458A can measure DC into tenths
of PPM, while I have nothing in my lab that can reliably produce
that, whereas it can only measure AC to tens of PPM, while I now
have a fully passive box which can generate it down to tenths of
So is volt-nuts DC only, or are anybody playing with AC also ?
