USB Hub Tester Voltage/Amps Power Meter Monitor Detector Tester Multimeter, Test speed of chargers, cables, capacity of power banks Current Voltage

Mudder USB Hub Tester Power Current Voltage Monitor Detector
This test can be a USB charging current, voltage, discharge capacity, intelligent devices. It can be very easy to find digital device charging problem. Tester three dimensional size 58 * 28.5 * 15mm (without cable), about 16 cm length of the line. The only button on the tester is used to view and test data switch, the tester can store 10 groups of test data. USB output port can be connected to a data line, a discharge resistor or the like cable device comprising a data communication function, the data does not affect the data transmission line. Test specifications, voltage can not exceed 7V, current can not exceed 3.5A. Note : When the voltage is lower than 4.7V on the instrument display or higher than 5.3V, the LCD screen will flash, Does not affect the use.
Input : 3-7V/50mA~3500mA Onput : 3-7V/50mA~3500mA
Capacity : 0~19999mAh
Communication function : Yes
Parameters adjusting fuction : Yes
Equipments for parameters adjustment : One electronic load, one constant current source.
Parameters that you can test : Voltage of battery, current of battery, value of discharging capacitor.(Total ten parameters)
Clean the data : Push the button until the parameters changed to next sets of parameters. Then release the button. Then the next sets of parameters will be started and they will start from zero.
Over voltage or under voltage : An arrowhead will be shown in LCD screen and LED background will flash. Push the button and LED will be light without flash. It will last 30s. Turn on model : The LCD screen will show all parameters within 1s when you connet power supply by MicroUSB or male plug of USB with wire.(It is to check whether the LCD screen is good or not). Then you can see the parameters used last time(capacitor and which set of parameters).You also can see the current voltage, current and over voltage or under voltage.
