All measurement data can be saved! Statistical calculations are performed using multiple measurement values for standard determination.
The "OST-828" is an automatic measuring instrument that measures the minimum resonance frequency Fo and impedance Ze of a speaker using a constant voltage method, performing statistical calculations with multiple measurement values for standard determination. All measurement data can be saved. Additionally, it calculates the values of Q (Qes, Qms, Qts). The DC resistance of the speaker is measured separately with a resistance meter and input via a key. 【System Configuration】 ■ Measurement Unit ■ Dedicated laptop for OST-828 (OS: Windows 10 64-bit version) *For more details, please refer to the PDF document or feel free to contact us.
