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
