USB Charger LCD Mobile Power Battery Current Meter Tester Voltage Detector

Description

KCX - 017 Micro USB Voltage Current Detector
Tester for Mobile Power Bank
Great Device to Know Current and Voltage!
Want to know how fast your smartphone and tablet PC are charging through the Micro USB interface?
This lovely KCX - 017 USB Current and Voltage Meter is all you need! It can show you the USB charging current
and voltage instantly.
Through it you can quickly find out device's current and voltage stage, like USB cable, USB wall charger, car charger
or solar panel charger, which gives you the fastest charging performance! Flexible, easy to use. KCX - 017 USB Current
and Voltage Meter reads the charging status to you in real-time style!
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
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.
7.  Check the parameters : Quick beat the button double times(within 0.5s), then  it is checking model.
The LED background will be flash.Then you can see the next  set of parameters in LCD screen. Quick beat the
button double times again, you  release 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 and  LED 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 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 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 than  4.7V on the instrument display or higher than 5.3V,
the LCD screen will flash, it does not affect the use.
Application examples
Because mobile phones and digital devices at low battery or full charge, the  current and voltage is not a stable value,
the application example of the  discharge
device is a USB 1A or 2A discharge resistor.
Note: This data is mobile power discharge capacity, the battery capacity is not, a
ccording to our experience, the discharge capacity is about 1.9 times the battery capacity.
The former Test Reference Manual Tester discharge capacity value is cleared, and the mobile power is fully charged.
