[rememberme]YouN LCD USB Charger Capacity Current Voltage Tester Meter For Phone Power Bank

Welcome to my store! We will provide you high quality goods at the most favorable prices, as well as good pre-sale and after-sale service. Brand Name:ALLOYSEED Package:No Model Number:93815 Type:Network Repair Tool Kit Input Voltage:LCD USB Voltage Current Detector Description: 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 60 X 28.5 X 15mm (without cable), about 15cmlength of the line. The only button on the tester is used to view and test data switch, thetester can store 10 groups of test data Specifications: 1. Input Voltage: 3V - 7V 2.Input current: <3.4A 3. Parameters that you can test: Voltage of battery. Current of battery, value of discharging capacitor. (Total ten parameters) 4. Communication function: Yes 5.Parameters adjusting function :Yes. Equipment for parameters adjustment: One electronic load, one constant currentsource. Voltage of constant current source should be set to 8.5V Thereare 3A, 2A, 1A and 0.3A models for current adjusting. Here is a example for 3A: When you set electronic load at 3A model, the current will be adjusted step bystep. It will cost you about 10 seconds and you can see the result changing procedure in the LCD screen. When you see the 3A result shown in LCD screen, theadjustment process is finished. You can shut off the electronic load and theparameters will be saved automatically. 6. Clean the data : Push the button until the parameters changed to next sets ofparameters. Then release the button. Then the next sets of parameters will be started and they will start from zero. 7.Check the parameters : Quick beat the button double times(within 0.5s), thenit is checking model. The LED background will be flash.Then you can see the nextset of parameters in LCD screen. Quick beat the button double times again, yourelease the parameters checking model. LED background be be light with flash. 8.Over voltage or under voltage : An arrowhead will be shown in LCD screen andLED background will flash. Push the button and LED will be light without flash. It will last 30s. 9.Turn on mode l: The LCD screen will show all parameters within 1s when you connect power supply by Micro USB or male plug of USB with wire.(It is to check whether the LCD screenis good or not). Then you can see the parameters used last time(capacitor andwhich set of parameters). You also can see the current voltage, current and overvoltage or under voltage. Please see following illustration. USB output port can be connected to a data line, a discharge resistor or thelike cable devic 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 than4.7V on the instrument display
