Brief introduction
ZC5990B loudspeaker F0 tester is a special test equipment with very good test accuracy, accuracy and stability. When the test frequency range is set to 400Hz, the resolution can reach 1Hz. The smaller the test frequency range, the higher the resolution, which is very beneficial to the F0 test of the low frequency loudspeaker (box). A 4.3-inch color LCD screen is used, which can directly display the F0 curve of the speaker.
Performance characteristics
- Using the traditional frequency method test principle
- Novel sweep frequency RC oscillator circuit and digital frequency counter
- Can quickly test and display the resonant frequency F0 of various types of speakers, and can set the upper and lower limit ranges
- The pass/fail judgment circuit is used to test and judge whether the speaker is qualified or not by means of sound and light prompts
- Suitable for testing and use on the production line
