ZC5820 speaker life tester

Scope of application

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

Signal source: built-in sine wave generator and frequency sweep controller, can be stored in various formats of audio files
Two sets of voltages can be arbitrarily set up to 20 channels at the same time to monitor, automatically record and display voltage/current/DCR/temperature rise/test time and status
The test voltage is automatically corrected, the accuracy can reach ≤1%, and the display is 0.001V
8-inch LCD panel, richer display content, larger fonts, easy to observe
Interface: front panel signal data input interface (USB), rear panel USB, LAN network port
Temperature rise measurement range: 0~200℃, measurement accuracy ≤5%±1℃
Support multiple working modes: continuous, intermittent, and debugging. Among them, the minimum interval supports 0.5s, and the voltage can still be accurately measured
