THE AUDIO MULTIMETER AND HANDHELD DYNO.  MEASURE TRUE AMPLIFIER POWER!  MEASURE IMPEDANCE OF SPEAKER BOXES.  MEASURE VOLTAGE DROPS, AND MUCH MORE!

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)
• Measure Frequency of a Sine Wave

WHAT IS INCLUDED?

• The AMM-1 tool
• Protective silicon rubber boot
• Harness
• This manual
• Pride of ownership
