Just for all on the list.  This reply is inaccurate.  All of my DMMs as
well as most I've seen in my price range are 10 meg input resistance.
The resistor array that I have presented is a tried and true method used
by TV repairpersons since the 1950's.  Regardless of any theoretical
challenge, the practical application proves it works.

As I mentioned, I regularly use a 100M and 1.2M divider and it does work
well with a 10 M meter.

Mouser now also has a 1 GigOhm Ohmite SLIMOX 2Watt in stock for the
exact same price ($4.20).  Coupling with a 12 Meg low end resistor or
chain thereof allows DMM to read directly in Kilovolts.
Again,
This would work properly only if your DMM input is >> 12 Megohm.
