   It can be done.

   I would describe it differently.  Use of words to describe this is
   tricky.

   He may not have been familiar with shunts, many people aren't,
   Or he may not have understood the description.

   'shunt' is a term used when discussing current meadurements.
   (When extending a voltmeter range 'multiplier' is the word...)

> nor resistors, but wouldn't the current have some effect on the meter's coil?

   Is current or voltage being measured?
   Both?
   (When using coil typoe meters, there is always some current involved....
   the discussion can get complicated....)
