** Understood but I dont expect someone to be running a 5KV meter at 5KV, in
that case Id configure for 10KV and not have to worry about a new scale (-;

##  For a 5 kv meter,  I usually use a 0-500 micro-amp  ammeter.  ( half a 
ma)..
+  a 10 meg ohm resistor. ( like 5 x 2 megohm resistors in series etc) .
Then the 0-500ua scale  reads  0-5000 volts.

##  The 0-10 kv meter's of course use a 0-1 ma meter...and the same 10 
megohms
worth of resistance.    The 0-1ma meter now read 0-10 kv.

##  The above two  configs  will then work on any amp..from 0-10 kv, with 
the
dividing point being 5 kv.

## I need simple, and you are correct, why use a 0-1ma meter to read 0-5 kv.
A lot of these meter's are not easy to take apart, and swap scales etc.
