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

Nothing about distortion detection from what I can tell

There is a clipping light in it thats why i ask

I didn’t even see that. Maybe @audiofanaticz can chime in. He sells some of these meters

the AMM1 is measuring live, so if there is no load there's no measurement. if you have a resistor pack you could use the AMM1 to help set gains. resistors with a high wattage rating become very expensive very quickly. i'd just fork over the money for a DD1 or DD1+. now if you can get a measurement without a load, that's beyond me of how you could make that happen without a resistor of some sort.


if nothing changes, nothing changes
