Supports 360-degree arbitrary rotation of the screen to meet any angle reading.
Voltage, current curve - online mobile phone, computer: automatically change the range within 0.00A-3.00A measurement range, real-time display of fluctuations. In addition, you can press the "Next Page" button to switch to the voltage measurement waveform diagram, automatically change the range within the range of 4.5V-24V measurement, real-time display of voltage fluctuations.
Wire resistance measurement: After the data line is inserted, the screen of the tester turns black, indicating that the pressure difference is too large; the tester enters a 4.5V power-down state and needs to reduce the load current, and starts measuring from the first step; after the wire resistance measurement is completed, the test is performed. The meter will restart measurement after the next power up.
Notebook Charging Measurement: When the notebook is powered, prepare two Type-C cables, one for connecting the power supply to the watch, and one for connecting the watch to the computer to measure the charging data of the notebook.
