I meant Zs of final circuits. Not the Zs at DB for which you need the board to be open.
After insulation resistance I'd do supply polarity, Zs at DB, then PFC, then put the lid back on, energise the board, then do the Zs of final circuits.

One person says Ze another Zs at DB can we please come to a common denominator? If it's a DB test, then it's a Zs at DB. And that's not even my question.

I'm not talking about Ze/Zs at DB at all. It's a test done on a dead board right? So is PFC test i.e. I don't need to energize the board. Only for the Zs of final circuits I need to energize the board. So I thought would it make sense to change the sequence, do the PFC at DB then the Zs of final circuits.
