Kcx-017 LCD USB 3V-7V Voltage Current Detector Power Tester

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 current  source.
Voltage of constant current source should be set to 8.5V  There  are 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 by  step. 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, the  adjustment process is finished. You can shut off the electronic load and the  parameters will be saved automatically.

6.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.

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. Please see following illustration. 

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.

  • Вполне рабочая штука. Очень удобно замерять ёмкость повербанков и батарей телефонов. Запоминает последнее значение замеров, так что можно продолжить измерять емкость даже с перерывом, после отключения тестера от питания.
