Page 2: Table Of Contents
Table of Contents The purpose of the AMM-1 What is included About the design Specifications Power Requirements How to Use Measuring DC Voltage Measuring DC Voltage Drops/Peaks (MIN/MAX) Measuring AC Voltage and AC Current Measuring VA and Power Factor Measruing AC Frequency and Impedance...
Page 3: The Purpose Of The Amm-1
The purpose of the AMM-1 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 ...
Page 4: About The Design
About the design When you pick up the AMM-1 know that you are holding a precision piece of equipment. If treated as such it should provide you with many years of reliable service. We have chosen a 9V battery as a power source for a few reasons: ...
Page 5: Power Requirements
Power requirements Pull the silicon rubber boot off of the unit by starting at one end and pulling off towards the other end. On the back side you will see the battery compartment. Slide battery compartment cover off towards bottom end of unit to reveal the 9V battery compartment.
Page 6: How To Use
Use caution when attempting to measure! Menu System The AMM-1 uses a menu system to select the mode of operation. The tool has 7 modes of operation. They are accessable by pressing the MODE button. It is a circular menu and is setup like such: DC Voltage --->...
Page 7: Measuring Dc Voltage
Measuring DC Voltage 1. Power on the AMM-1 by pressing the ON button 2. Unit will power up, display internal battery condition, and then land on the DC Voltage Screen. 3. Connect the probes to the banana jack inputs on the AMM-1 4.
Page 8: Measuring Ac Voltage And Ac Current
To measure an AC Voltage: 1. Power on the AMM-1 by pressing the ON button 2. Unit will power up, display internal battery condition, and then land on the DC Voltage Screen.
Page 9: Measuring Va And Power Factor
That is incorrect. It would be 5000 VA. Now since the subwoofers are not pure resistors the voltage and current will likely be slightly out of phase. With the AMM-1 the competitor repeats the test and finds the output was 5000 VA with a power factor of 78%.
Page 10 7. Connect the voltage harness to the banana jacks and then to the amplifier speaker outputs (+) and (-) 8. Power up AC current source (amplifier) and apply a signal with a tone generator or tone CD. 9. The AMM-1 will display the VA and the Power Factor...
Page 11: Measuring Ac Frequency And Impedance
Measuring AC Frequency and Impedance The AMM-1 allows the user to measure impedance of a speaker load at any frequency from 20Hz - 1kHz at any power level (up to approx 15,000 Watts). This is very powerful information to have when designing subwoofer enclosures.
Page 12 Measuring AC Freq and Imp (cont.) How to measure AC Impedance 1. Power on the AMM-1 by pressing the ON button 2. Unit will power up, display internal battery condition, and then land on the DC Voltage Screen. 3. Press the MODE button four times (or hold down) to get to the Frequency &...
Page 13: Real Time Power Mode
Real Time Power Mode In this mode the AMM-1 will show the True Power compensated for both Power Factor and clipping of the signal in a live mode. How to measure True Power 1. Power on the AMM-1 by pressing the ON button 2.
Page 14: Dyno Mode
Dyno Mode In this mode the AMM-1 will act like our AD-1 Amplifier Dyno. The highest True Power reading during a "run" will remain on the display. The power reading is compensated for both Power Factor and clipping of the signal.
