Product Summary

Model OST-828 can measurement lowest resonant frequency(Fo) and impedance(Ze) of the speaker by the constant voltage anodizing. This model collects the statistics with plural measurements and calculates and does the standard judgment.
All the measurement data can save it, furthermore, this model calculates the value of Q(Electrical Q of driver, Mechanical Q of driver, Total Q of driver).

Product specifications

Fo measurement range : 15Hz to 10kHz(impedance range : 0.9Ω to 254Ω)
Ze measurement range : 1Ω to 100Ω(at 50Hz to 10kHz 1point)
Measurement time : Fo about 3sec Ze about 1sec
Q measurement : Electrical Q of driver, Mechanical Q of driver, Total Q of driver
