Rapid testing the lowest resonant frequency Fo value , complies with American EIA & ANSI stds., auto judging PASS / FAIL, suitable for use in production line,incoming parts inspection and quality control dept.
The Lowest Resonant Frequency Fo value is one of the important parameters of the loudspeaker, 7117C can automatically & instantly display the Fo value of loudspeaker in digits, no manual searching is needed, moreover, The Upper / Lower limits can be set by 7117C, auto judge the PASS / FAIL, very suitable in production line for 100 % Q.C. testing. 7117C is not only suitable for loudspeaker firms, but also suitable for : incoming inspection of the loudspeaker by the audio, monitor,multimedia firms....etc.
Very fast in auto-searching the lowest resonant frequency, Fo value can be displayed in just 1~1.5 seconds.
Upper / Lower limits can be set, auto judge PASS / FAIL, auto-searching and judging time require only 0.3 ~ 0.7 seconds
Displays in digits, accurate, no visual error. Complies with ANSI & EIA std. of U. S. A. |
