Simultaneous display of voltage and current mAH data, easy to view can detect mobile power output mAH2. Multi-group detection data preservation, power failure preservation function does not affect data transmission3. Higher precision, current basically will not jump current sampling 25 milliohm loss is smaller4. With precision current calibration function, the current accuracy is higher5. Safety charging, real-time monitoring and control of your charging dataMain .Input voltage: 4-30VVoltage resolution: 0.01VTest current: 0-3ACurrent resolution: 0.01ACapacity range: 0-19999mAHAccuracy: plus or minus 1%Line loss: 0.1 ohm or soTest content: battery voltage, current, discharge capacity (a total of 10 groups of data)Instructions for use.Measure voltage and current:USB male plugged into a 5V charger, female socket plugged into cell phones and other devices, direct reading of voltage and current Measure battery capacity:The use of TP4056 and other linear charging circuit through this capacity meter to completely dead battery charge to completely full, capacity reading for the battery capacity, the use of this method can also be measured cell phone charging capacity, and can even calculate cell phone charging efficiencyMeasure the quality of the MicroUSB cable:Female socket inserted into cell phones and other devices, first use the machine's male head into the 5V charger, remember the voltage, then use the MicroUSB cable from the 5V charger into the machine MicroUSB hole to remember the voltage, the smaller the voltage gap MicroUSB cable quality is betterMeasure the mobile power output capacity and efficiency:First connect the machine to the mobile power, open the mobile power, long press the button until the capacity data to zero, insert the phone more charging until the mobile power is not charged automatically shut down. Note that this mAH is much smaller than the nominal mAH, output mAH * output voltage 5V / battery mAH * battery voltage 3.7V = mobile power efficiencyData Zeroing.Press and hold the button until (the first group of data) becomes the next group and then release the button to automatically jump to the next group of data starting from zero.Data View.Double-click the button (within 0.5S), enter the view data view mode, the backlight LED will flash, and then display the next group of data, double-click to exit the data view mode, the backlight LED long light.High or low voltage.LCD arrow, backlight LED will flash, alarm prompt. Press the button LED is always on for 30S.Power on status.Power on via MicroUSB or USB with cable, LCD display all the contents of 1S (to detect whether the LCD is intact), then display the last data (capacity, and several groups of data), the current voltage, current and high or low voltage promptList.Tester *1
