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. For lots of information on impedance

sweeps and what they mean, please visit our website

www.DAmoreEngineering.com and visit our products

section. Here you will find our IM-SG tool. There is a

Free Download to the owner's manual for that tool there

that contains lots of useful info on this topic. Enjoy

How to measure AC Frequency

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 AC Frequency and Impedance screen.

4. Connect the voltage harness to the banana jacks

and then to the amplifier speaker outputs (+) and (-)

or the AC source of interest. As long as the signal

input is over a few volts the frequency of the sine

wave will be displayed
