Product overview

Multi-interface LCD display

How to use

Connect power supply equipment (Such as charger, power bank, USB cable, etc.) to the corresponding input interface of this USB tester. Then, connect your device, such as Laptop, Tablet, Smartphone, and more, to the corresponding output interface of this USB tester.

Note:

1. If you use the USB cable to connect (Such as charging your laptop), please pay attention to the quality and input of the cable, especially the maximum current.
2. While charging your smartphone or computer, please do not use Micro USB input interface.
   

Operation

1. Screen display settings.
   Click the MFB to switch the display interface when the USB tester is power on: Chinese interface – English interface -Personalized interface 1-Personalized interface 2
   – Personalized interface 3 – Over voltage protection – Low voltage protection – Over current protection – Off

   Interfaces	Features	Operations
   Chinese interface English interface Personalized interfacel Personalized interface 2 Personalized interface 3	Switch next interface.	Click MFB.
   	Reset capacity.	Double-click MFB.
   	Reset electric quantity.	Triple-click MFB.
   	Reset time.	Click MFB four times.
   	APO settings: Set AO../OFF/1-24 hours AO.. – Smart monitoring the APO. OFF – Turn off the APO. 1-24 hours – Auto power off when reaching the setting time.	Click MFB five times to access the APO settings. Click MFB to decrease the time(Click MFB and hold it to decrease quickly). Double-click MFB to increase the time (Double-click MFB and hold it to increase quickly). Wait for 10s until the current value is confirmed.
   	Standard current	Click MFB seven times (Only allow to adjust current when there is no device to be charged. After adjusting, the current is 0.00A. If you adjust the current during charging device, please disconnect device and then adjust the current again.).
   	Flips the screen to 180°.	Hold MFB for 2s.
   High voltage protection	Input voltage > the set value (1.00V-35.0V), the tester will cut off its output and alarm to remind.	Click MFB to switch next interface. Double-click MFB to increase the value, and hold it to increase quickly. Triple-click MFB to decrease the value, and hold it to decrease quickly.
   Low voltage protection	Input voltage < the set value (0.00V-34.0V), the tester will cut off its output and alarm to remind.
   Over current protection	Current > the set value (0.20A-15.0A), the tester will cut off its output and alarm to remind.

   
   Note: AO.. function. Detecting that the power is always less than 2W within 1 hour, the product will automatically cut off the output.

2. Background settings.
   Turn on the USB tester while holding the MFB. It will enter into the interface of Background Settings. Click MFB to switch interfaces: Voltage adjustment – Current adjustment – High voltage protection  – Low voltage protection  – Over current protection – Capacity compensation factor.

Note:

1. “Over voltage, Low voltage and Over current protection” is the same as the above mentioned function, whose only difference is the operation.
2. Do not adjust voltage and current if there is no accurate 5.00V power supply and 2.00A constant current load. If there is wrong adjustment due to your misoperation, you can press and hold the MFB for 2s to reset the factory settings.
   

   Interfaces	Features	Operations
   Voltage adjustment	The externally connected 5.00V voltage as calibration reference voltage.	Double-click MFB (If the externally connected 5.00V voltage itself is not accurate, the calibration will affect the voltage accuracy of the tester.)
   Current adjustment	The externally connected 2.00A load with the constant current as calibration reference current.	Double-click MFB (If the externally connected 2.00A constant current load itself is not accurate, the calibration will affect the accuracy of current of the tester.)
   High voltage protection	Input voltage > the set value (1.00V-35.0V), the tester will cut off its output and alarm to remind.	Double-click MFB to access the setting state: Click MFB to decrease the value, and then hold it to decrease quickly. Double-click MFB to increase the value, and then hold it to increase quickly. Wait for 10s until the current value is confirmed. The instruction of capacity compensation factor: For a example, when monitoring the actual capacity of power bank, if the total internal loss is 35%, the actual capacity is x(1+0.35) – that is x1.35.
   Low voltage protection	Input voltage < the set value (0.00V-34.0V), the tester will cut off its output and alarm to remind.
   Over current protection	Current > the set value (0.20A-15.0A), the tester will cut off its output and alarm to remind.
   Capacity compensation factor	The capacity of the current voltage multiply by capacity compensation factor to get the final displaying value (x0.50-x1.50).
   RESET!	Screen displays RESET and restore to factory state.	Hold MFB for 2s.
