The Simpson 260 voltmeter has a 20,000 ohms per volt scale.
Multiply the full scale voltage by 20,000 ohms.
Note that the lower scale like 10v will have a small resistance which
means it puts more of a load on the circuit under test.
A digital voltmeter may only present 10 Megohm of load which is
virtually no load.
