You never need to measure the DC voltage.  It's 
always 1.414 x the Erms, so you are actually 
measuring Erms and then just recalibrating the 
meter face to reflect the actual measured DC 
potential.  No messing around with HV resistors, etc.

When I mentioned the NST method I was thinking he
wanted to measure the AC input to the DC filter -
didn't engage brain. Transformers don't work well at DC.

An NST will work for AC, but not DC.
