LCD Dual USB Mini Voltage and Current Detector Mobile Power USB Charger Tester Meter, fast charging ,mini universal meter Model: UP® LCDV02 Item description: Input Voltage: 4 – 6V Input Current: 0 – 3.5A Voltage measurement error : when 4 - 6V , ±1% Current measurement error : when 50~3500ma , ±1% Maximum Capacity Value : 99999 mAh Maximum Save Data Group: 9 USB Port Description : 1. USB1 port : For Charging , contain CW3002D chip (For Universal USB fast charging adapter features), 2. USB2 port : Data Transmission and also for Charging 3. Micro USB port: For input use . Button Function : 1. Click the button can view the data group one by one (total 9 groups), click one time, the screen will display next group of data. ( When this product is doing test , you could view other group’s data , for example , Data Group No.5 is showing the current testing data, click the button one time ,screen will show Group No.6’s data with flashing, click one more time will show the Group No.7’s data with flashing also . After 5 second without any operation , the screen will come back to show the (current) Group No.5’s data ) 2. Double click the button , current data will be saved and then change to next group of data ; 3. Holding button ( about 2-3 seconds) , current data will be deleted ; 4. When input Voltage is over 5.7v or lower than 4.6v , the Screen’s Voltage data will flash ( 1Hz frequency) , Buzzer will alarm ( sound “D” , repeated every 5 seconds) ; When Voltage is over 6V , USB port will be shut down automatically in order to protect the device , and Buzzer will alarm ( Sound : “D – D – D “ , repeated every 5 seconds ) 5. When Output Current is over 3.1A , the Screent’s Electric Current data will flash ( 1Hz frequency) , Buzzer will alarm ( sound “D” , repeated every 5 seconds) ; When Output Electric Current is over 3.5A , USB port will be shut down automatically in order to protect the device , and Buzzer will alarm ( Sound : “D – D – D “ , repeated every 5 seconds ) PS: After the USB port shut down ( Voltage over 6V or Output Electric Current over 3.5A ) , this item have to be shut down( it means just take out from power) then use again . Please Notice: 1. Input Voltage must not over 6V, or it will destroy the item ; 2. If you use “USB load resistance” ( sell separately ), must not work for a long time during Electric Current is over 3A ; 3. CW3002D chip (For Universal USB fast charging adapter features) can only work in 4.5 – 5.8 V (input Voltage) ; 4. The “USB load resistance” ( sell separately ) can be used to check Power Bank’s Battery Capacity, due to discharge test has some error , suggest use the test result times 1.9 ( for example : 100 mAh x 1.9 ) in order to calculate more closer to Battery Capacity ; 5. The “USB load resistance” ( sell separately ) can be used to check Cellphone Battery Capacity, due to discharge test has some error , suggest use the test result times 0.9 ( for example : 100 mAh x 0.9 ) in order to calculate more closer to the Battery Capacity.
