Brief introduction

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
