Brief introduction

The ZC5990D 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

  • High accuracy, the frequency error of the test signal ≤0.01%
  • High precision, the test error when five times of retracement is ≤0.1%±1Hz (±1 word)
  • The test frequency range is wide, 20Hz~20kHz when testing the full frequency range
  • Fast test speed, can directly display F0 curve
  • Convenient operation and clear display
  • Exquisite structure, easy to carry
