When this USB tester connect to USB-C device and USB-A to USB-C cable, you should insert the OTG adapter (Micro USB adapter) into USB tester to trigger the PD charging function. Then the USB tester can be used normally. 2. If there is current in the tester without connecting load, press and hold the key of USB tester, then connect to device and calibrate to zero. During calibration, the output must not have any current consumption. Important: Please download more information from Product guides and documents. The product is constantly updated and new content is added, so sometimes the version you receive may be different from the description, but it does not affect the quality and use of product. Detect Charging & Discharging condition of your devices. Wide range of application, can be applied to test Type-C and Micro USB devices. Under the circumstance of the constant power supply and sustained load, the larger voltage and the lower voltage drop of the USB cable detected by this USB tester means that the better quality of the USB cables will be. USB tester provides real-time charging parameter information of charging status to you, ensure a safety charging environment to your devices. Note: If the USB tester doesn’t display any parameters, please insert the USB Micro adapter into the side hole on the USB tester to trigger the PD charging function. Make sure the power bank to be tested is fully charged firstly, then connect to this USB tester and reset the capacity and electric energy by long pressing, and then fully discharge with this USB tester and 5v load till power bank run out of its energy. The reading on this USB tester is real data of capacity of your power bank. Plug the USB tester into the charger and connect an adjustable current load; Perform current adjustment and test the current and voltage data of the charger; Let the charger be connected to the current loader for a long time to check the stability of the charger. Our USB tester can meet the transform of two kinds of output. When USB-A input connect to your charger, the USB-A output and Type-C output both support testing electricity. Note: the Micro USB Adapter should be inserted at this time. When charging the notebook, connect a YOJOCK USB meter to monitor real-time voltage, current, capacity, power, temperature and other electric parameter information.
