Detailed Product Description

Electro-acoustic Testing Machine

Main testing function:
1KHz sensitivity, average sensitivity, character curve of sensitivity frequency, AC impedance, impedance curve, polarity estimating and expended electricity.

Main capabilities and characteristics:
1.It is designed Special for producing and testing. It could test not only finished product kits but also single loudspeakers and transmitters. It could test three kinds of parts (left and right tracks, microphone) at one time and it takes only 3.5 seconds for a full-function testing.
2. The meter itself provides the power supply(Voltage:1.5V,2.0V,2.5V,3.0V,4.5V,6.0V; Impedance:680Ω,1.0KΩ,1.5KΩ,2.2KΩ,3.3KΩ,4.7KΩ) which is for testing electret capacitor microphones.
3. You could emendate the double track IEC318 artificial ears with man-made zero error.
4. The software in the meter has a function on amending any frequency point on the frequency response curve which is for microphone.
