Price: USB tester single one (without other accessories)

Dimensions: Length Width 28MM * 60MM * 15MM thick

Cable length: 150MM

input mirco usb / usb port

User as current protector and test for power bank voltage and current

LCD screen with backlight function even low light conditions can also be clearly seen

Voltage and current and the discharge capacity USB socket can be tested and mobile power charger

MicroUSB data line interface can be tested load capacity

Performance parameters:

1, the input voltage: 3V-7V

2, the input current: <3.4A

3, the test: battery voltage, current, maximum discharge capacity z range 19999MA (total of 10 sets of data)

4, the communication function: (inputs and outputs can be used for USB communication function, that is, B + B-D + D- four lines connected)

5, the data is cleared: hold down the button until (the first of several sets of data) to become the next group and release the button to automatically jump to the next set of data is cleared

6. View: Double-click the button (0.5S or less), enter to view the data view mode, backlight LED will flash, and then look at the next set of data is displayed, double-click to exit the View mode, long bright LED backlight

7, voltage warning: high or low voltage, LED backlight flashes, alarm prompt, press the button LED lit 30S

8, turned: powered by USB MicroUSB or male, the entire contents of the LCD display 1S (detection LCD is intact) then displays the last data (capacity and third sets of data), the current voltage, current and voltage bias high or low tips

Instructions for use:

Measuring voltage and current:

5V USB male plug in the charger, mobile phones and other devices plugged female readout voltage and current parameters directly

MicroUSB line quality measurements:

Female plug mobile phones and other devices, first with the native male plug 5V charger, remember voltage, MicroUSB cable into the machine and then bore in mind that the voltage from 5V MicroUSB charger MicroUSB line voltage the better the quality the smaller gap

mirco USB inputUSB input

Not more than 7V，current not more than 3.5A

Test between power bank or mobile devices

High or low voltage alarm:

Arrow LCD backlight LED will flash, alerting prompt, press the button LED lit 30S.

Turned on:

Powered by USB MicroUSB cable with male or the entire contents of the LCD display 1S (detection LCD is intact) then displays the last data (capacity and third sets of data), the current voltage, current and high voltage or bias low hints.

Calibration data set:

An electronic load device, a constant current source.

Constant current source transferred to 8.5V and less than 10V (recommended 9V) electronic load is set to CC mode (constant current mode) 3A, 2A, 1A, 0.3A, respectively, four current calibration.

In 3A, for example: When 3A calibration, electronic load set constant current mode 3A, LCD fuel gauge will automatically slow the current calibration (about 10S) can see the current will change the LCD screen, turn off the electronic load calibration automatic data protection.
