 Product overview：
Micro USB input
Type-C output
 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 smart phone or computer, please do not use Micro USB input interface.
 Operation

High voltage protection
tester will cut off its output and alarm to remind.
Input voltage < the set value (0.00V-34.0V), the
Low voltage protection
tester will cut off its output and alarm to remind.

Over current protection
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
adjustment - High voltage protection
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.

Wait for 10s until the current value is confirmed.
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.).
Hold MFB for 2s.
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.
- Over current protection
Double-click MFB (If the externally connected 5.00V voltage itself is not
accurate, the calibration will affect the voltage accuracy of the tester.)
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.)
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.
Hold MFB for 2s.
