USB Digital Voltage and Current Meter, FNB48S, Multifunctional Fast Charging Test with Data Recording Function

1. It can switch between 1-bit or six-digit display with a single key. The maximum resolution is 0.00001, and it can monitor the changes in voltage, current, and power during the charging process in real-time.<br> 2. This product uses a USB3.0 interface with a 9-pin design, which is downward compatible with USB2.0 and has the transmission rate of USB2.0. There is no need to use the original data cable, and it can directly test the charger protocols of some mobile phones.<br> 3. This product can record 10 sets of measurement data, and users can use these data to calculate the battery capacity.<br> 4. This product directly provides the calculation formula on the product, which is to multiply the battery capacity by 1000.<br> 5. This product supports reading the data of E- and DASH data cables. After connecting the data cables, users can easily read the data of E- and DASH data cables.<br> 6. This product supports the screen flipping function. Through the gravity sensor, the screen can be freely flipped. Users can also turn off the gravity direction recognition and long-press the middle button to flip the screen.<br> 7. This product uses the differential pressure method to measure the cable resistance. When used in conjunction with a constant current load, it can easily detect the cable resistance.<br> Model: FNB48S<br> Version: Without Bluetooth<br> Monitoring voltage: 4 - 24V<br> Monitoring voltage resolution: 0.00001V<br> Monitoring voltage accuracy: (0.2% + 2)<br> Monitoring current: 0 - 6.5A<br> Monitoring current resolution: 0.00001A<br> Monitoring current accuracy: (0.5% + 2)<br> Monitoring power: 0 - 156W<br> Monitoring power resolution: 0.00001W<br> Monitoring power accuracy: (0.5% + 2)<br> Load equivalent resistance: 0 - 9999.9<br> Load equivalent resistance resolution: 0.0001<br> Load equivalent resistance accuracy: (0.5% + 2)<br> Capacity: 0 - 9999.99Ah<br> Energy consumption: 0 - 9999.99Wh<br> Cable resistance: 0 - 9999.99<br> D+/D- voltage: 0 - 3.3V<br> D+/D- voltage resolution: 0.001V<br> D+/D- voltage accuracy: (1.0% + 2)<br> Device temperature: /<br> Color: Black<br> Material: PCB + Metal<br> Packaging contents:<br> 1 protocol capacity testing tool<br> Only the above packaging contents are included, and other items are not included.<br> Note: Light reflection and different displays may cause the color of the item to vary slightly from the actual product.
