Supports USB-A/Type-C/Micro-USB and other multi-port conversion applications - 1.44-inch high-definition color Chinese interface high-definition display screen, 8A high current. 4 function buttons, 5 universal interfaces, 7 display interfaces, etc. Line resistance measurement, all kinds of USB chargers, power , data cables, etc.; high- measurement of various devices. Line resistance measurement - After inserting the data cable, the tester screen turns black, indicating that the voltage difference is too large, the tester enters the 4.5V power-off state, and the load current needs to be reduced and the measurement starts from the first step again. After resistance measurement is completed, restart the measurement after the tester is powered on next time. Supports 360-degree screen rotation, meeting readings at any angle - Long press the button corresponding to the horizontal menu bar to rotate the screen, so that various digital devices can be inserted at any angle and can read forward, making measurement more convenient. Real-time current and voltage curve display, two modes and two curve detection - voltage and current curve detection; D+D- curve detection, real-time viewing of current and voltage fluctuations, such as abnormal charging, can be immediately discovered, it is an ideal choice for charging monitoring. Test various USB chargers and monitor the performance stability of the charger - Play and test various USB chargers, and you can easily test them with a constant current load. You only need to adjust the load knob to test the charging current and voltage values, let the charger be used for a long time with load, and detect the performance stability of the charger., Manufacturer: Akfldms
