What's so hard about putting a resistor in parallel with your meter?
Even better would be to understand why they specified VOMs with 20k/V sensitivity, and the implications with modern instruments.
Back in those days, the commonly-available multimeters were 1k/V and 20k/V VOMs and 11 Meg VTVMs. The cheaper 1k/V would load down the circuit and give an erroneously low voltage reading. With the 20k/V VOM and the VTVM, this error was usually smaller than the inaccuracy in the analog meter movement.
