The lowest resonant frequency Fo value, is one of the important parameters of the horn, 7117C completely without hand tuning mode can be automatically and immediately to the speaker Fo value measured and digitally displayed and 7117C can set upper and lower limits , automatically determine pass / fail, very suitable for the production line to make 100% quality inspection. 7117C is not only applicable in speaker manufacturer, is also suitable for: audio plant, multimedia works, monitor speaker factory ... etc. IQC
Find the lowest resonant frequency of high-speed automatic Fo value, Fo value read for 1 to 1.5 seconds.
Can be set on the lower limit, automatically determine the pass / fail, search time plus co-determination is only 0.3 to 0.7 seconds.
Digital display, accurate and no visual error.
In line with the US standard ANSI and EIA test.
