Expanded scale voltmeter, which one?
The picture doesn't show it as clearly as I had hoped. One resistor plug is connected to the "common" socket of the DMM and the other resistor plug is connected to the "V" socket of the DMM. The charge jack plugs in on top of the resistor plugs. One plug of the charge jack plugs in on top of the "common" resistor plug. the other plug of the charge jack plugs in on top the "V" resistor plug.
