Comprehensive test and measurement service provider-Shenzhen Weike Electronic Technology Co.
brief introduction
ZC5990D loudspeaker high-speed F0 tester is a single-chip computer control, based on the traditional frequency method of testing principles, set of analog and digital circuits in the body of the fully intelligent test instrument. It has the ability to quickly test and display the resonant frequency F0 of various loudspeakers, and real-time display the test voltage value. It can set the upper and lower limit ranges according to the specifications of the loudspeaker, and judge whether the loudspeaker is qualified or not by the test of pass/fail judgment circuit, so it is especially suitable for testing in the production line.
Technical indicators
