ZC5990B loudspeaker F0 fast tester

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.
