Newest LCD USB Charger Capacity Current Voltage Tester Meter For Cell Phone Power Bank & Voltmeter Free Shipping
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 fuction:Yes.
Equipments for parameters adjustment: One electronic load, one constant current source.
Voltage of constant current source should be setted to 8.5V Here is a example for 3A:
When you set electonic 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.
