ARCELI White Tail LCD Backlight LCD Digital Display USB Ammeter Voltmeter Charging Capacity Test Table Detector
Features: Simultaneous display of voltage, current and mAH data for easy viewing Can be mobile Detect output power mAH Multiple test data sets are stored Does not affect data transmission With higher precision, the current parameters do not jump USB plugs and MicroUSB ports are double powered to detect the MicroUSB line quality Current sampling 25 milliohms, less loss With the precise current calibration the current accuracy is higher (it was calibrated at the time of shipping). Performance parameters: Input voltage: 4V-30V Voltage resolution: 0.01V Test current: 0.05A - 3.50A Current resolution: 0.01A Capacity range: 0-19999mAH Accuracy: plus or minus 1% Line loss: approx. 0.1 ohm Test content: battery voltage, current , discharge capacity (10 data sets in total) List: 1x digital voltage measuring device
Product Features
- Measuring voltage and current: The USB plug is connected to a 5 -V charger connected, the socket is plugged into the mobile phone and other devices, and the voltage and current parameters are read out directly.
- Measure the quality of the MicroUSB cable: Connect the mobile phone and other devices, first insert the 5V charger into the plug, remember the voltage, and then insert the MicroUSB cable of the 5V charger into the MicroUSB hole of the device to remember the voltage. The better the quality of the MicroUSB cable, the smaller the voltage gap.
- Measure the output capacity and efficiency of the mobile power supply: First connect the mobile power supply to the mobile phone, turn on the mobile phone, print and hold the button until the capacity data returns to zero, and insert the mobile phone several times until the mobile phone works. The power is automatically turned off. The display capacity is the mAH of the cellular power when the device is turned on the next time.
- Data switching: Click the button to switch to the next data set, and double-click the button to switch to the previous data set Switch.
- Clear data: Press and hold the button for more than 3 seconds to delete the group data.
