I was wondering how can I find internal resistance of multimeter, in both voltmeter and ammeter capabilities?

I thought it was termed as input impedance but when I looked up the specs of multimeter, in example, Agilent 34410A Digital Multimeter, it said load impedance was 1 MΩ ± 2%, in parallel with <150 pF in True RMS AC Voltage, which did not make any sense to me at all.

I know how to measure experimentally load impedancemeasured internal resistances for both voltmeter and ammeter capabilities of multimeter but I wanted to compare this experimental value to true value of internal resistances and make percent errors. Help please
