Description Video: https://www.youtube.com/watch?v=nkL_pofkd10; Latest User Manual: http://www.mediafire.com/folder/77ueo252py4vc/AT34. Testers are widely used in the quality inspection of 3C digital peripheral products, the first choice for digital enthusiasts and electronic lovers. Real-time detection of the state of charge of the appliance, voltage, current, power and other indicators at a glance; Measuring voltage: 3.7V-30V; Measuring current: 0-4A. The AT34 used a 0.96-inch IPS high-definition color LCD display to display the state of charge of the appliance, voltage, current, capacity, energy, power, equivalent impedance, temperature and other indicators at a glance?160 degree wide viewing angle, high brightness and long working life. Fast charge recognition, widely compatible: AT34 supports QC2.0, QC3.0, for i Phone 2.4A/2.1A/1A/0.5A, for Andriod DCP, fast charge protocol identification, let you know the state of charge of the phone. Power-off storage data is guaranteed: AT34 has power-off storage function, which can store capacity and energy data when the mobile power is cut off, which is convenient for subsequent viewing and convenient for capacity energy measurement of mobile power. Note: Other USB testers that do not have a power-down storage function cannot test capacity and energy. Measure the quality of the charger: connect the same load, compare the no-load and the load, the greater the voltage drop, the worse the charger capacity is, the worse the quality; The voltage drop is not obvious or the voltage rises (leisure loss) Compensation function) The better the load capacity of this charger, the better the quality. 4-bit accuracy for more accurate measurements; Measure the load equivalent impedance and power; Thermometer function, Celsius and Fahrenheit free switching by using high-precision thermistor sensor; Supports high current test like USB3.0 interface mobile hard disk and U disk test, also compatible with USB 2.0,
