Brief introduction

The ZC1681B-Y multi-channel loudspeaker life tester is a newly upgraded stand-alone version of the aging tester. The outstanding function is that the setting and operation are very simple, intuitive and clear, suitable for laboratory personnel to operate, the new internal structure, faster heat dissipation, and more stable quality , Higher reliability.

Scope of application

Mobile phone speakers, receivers, MP3, tablet computers, laptop speakers, low-power TV speakers, etc.

Features

  • Signal source: Built-in sine wave generator and sweep frequency controller, dual SD card signal output, two groups can be used for aging test of different signals
  • Two groups of voltages can be arbitrarily set up to 20 channels for simultaneous monitoring, automatically record and display voltage/current/DCR/temperature rise/test time and status
  • The test voltage is automatically corrected, the accuracy can reach ≤2%, and the display is 0.001V
  • 7-inch LCD panel, richer display content, larger fonts, easy to observe
  • Temperature rise measurement range: 0--200°℃, measurement accuracy ≤5%±1℃
  • Support multiple working modes for normal intermittent debugging, the smallest intermittent support 0.5S, and still can accurately measure voltage
