Features:
1.Screen Reverse Function: The USB voltmeter supports the screen reversing function, can be flipped freely by gravity sensing. Or you can turn off gravity direction recognition and hold down the middle button to flip the screen.
2. (Pressure Sensitive Measurement) This USB voltmeter can measure the cable resistance by differential pressure. Can easily detect cable resistance when used with constant current load.
3. Real-time Monitoring: One key can switch between 5 or 6 digits displays, maximum resolution 0.0001, you can monitor subtle changes in voltage, current and power while charging.
4. Backward Compatibility: USB 3.0 interface, 9 pin design, backwards compatible with USB 2.0. No need to use the primary data cable, you can directly test the charging protocols for some phones.
5. (Measurement Data Recording) The USB voltmeter can record 10 sets of measurement data, and you can use the data to calculate the battery capacity. We add this calculation directly to this product and then multiply 1000 results in battery capacity.
6. Easy reading: USB voltmeter supports E-marker and DASH line data reading. After connecting the data cable, you can easily read the E marker and the chip of the DASH line.
