USB Charger Capacity Current Voltage Tester Meter For Cell Phone Charging Power LCD Display Volt Amp monitor for Battery
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 * 28.5 * 15mm (without cable), about 15cm 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
- Can not detect fast charging
Specifications:
- 1.Input : 4-30V/50mA~3000mA
- 2.Output: 4-30V/50mA~3000mA Capacity: 0-19999mAH
- 3. Parameters that you can test: Voltage of battery. Current of battery, value of discharging capacitor.
(Total ten parameters)
- 4. Communication function: Yes
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.
- 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.
- again, you release the parameters checking model. LED background be be light with flash.
- 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 connect power supply by Micro USB 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. 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.
- 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, it does not affect the use.
Package include
- 1 x LCD USB Voltage Current Detector Mobile Power USB Charger Tester Meter
