The Fluke 85RF II high frequency probe calibrates the DC output to be equal to the rms value of a sine wave input. It can be used with a DC voltmeter that has an input resistance of 10MΩ, ±10%. Voltmeters with higher input resistances are usable if an external shunt is put across the input terminals to decrease the input resistance to 10MΩ.
