Validating the Speaker Impedance, Transformer Impedance & Turns Ratio using my Audio Signal Generator (1000 Hz) w/ an amplitude less than 1.0VAC. The Fluke 27/FM has the ability to measure AC current from 40 to 1000 Hz, which makes this method and procedure simplistic in addition the ability to measuring AC voltages from 40 Hz to 30 kHz.
