Comprehensive test and measurement service provider-Shenzhen Weike Electronic Technology Co.
brief introduction
ZC5990B loudspeaker F0 tester is a test precision, accuracy and stability are very good special test equipment. When the test frequency range is set to 400Hz, the resolution can be up to 1Hz, the smaller the test frequency range, the higher the resolution, which is very conducive to low-frequency loudspeaker (box) F0 test.
Performance Characteristics
- Adoption of the traditional frequency method test principle
- Novel Sweeping RC Oscillator Circuit and Digital Frequency Meter
- Can quickly test and display the resonant frequency F0 of various types of loudspeakers, can set the upper and lower limit ranges
- Pass/fail discriminating circuit to test and discriminate whether the speaker passes or fails by sound and light prompts.
- Suitable for testing on production lines
