Steve Meade SMD AMM-1 Audio Multimeter/DMM/O-Scope/Power+Impedance Meter

Proudly Made By SMD / D'Amore Engineering
The purpose of this tool is to enable the user to:

Measure True Amplifier Power output into any load reactive or resistive
Measure Common DC voltages
Measure DC voltage drops during quick transients on cable runs or battery / charging systems
Measure Impedance of speakers at any power or frequency from 20Hz - 1kHz (box rise)
Measure Phase Difference between Voltage and Current into reactive loads (Power Factor)
Find Tuning Frequency of subwoofer enclosures
Tune subwoofer enclosures for maximum power transfer
Measure AC Volts (amplifier output)
Measure AC Amps (amplifier output)
Measure apparent power (VA) output, Phase Angle, and Real Power (Watts) of audio amplifier, or consumption of appliances that run on AC power
Measure Frequency of a Sine Wave
