[Test-Equipment] "possessed'" VOM(s)

Using an old resistor sub box and a precision resistor (in the X1 circuit), I simply placed the new resistor in the unused thru-hole already there.
This has been one of those things that has been bugging me, but just now had time to look at it.

Hi, Ron

Re: Sanwa YX-360TR mutlitester manual, Parts List, page 24 -

I see that R21 (19 Ohm resistor) used for X1 scale of the imported VOM
is shown in the parts list as "shunt", 
along with several other resistors used for Ohms readings.

Too bad they didn't include a schematic.  It sounds like they're using 
a separate current generator circuit and DC voltmeter circuit
across the sense terminals, like a VTVM or DMM Ohms circuit,
unlike the simple series Ohms circuit used in a Triplett 310 VOM.

Is zero Ohms full scale reading of the meter, like a standard series 
Ohmmeter?
