1. Resolution: 2.99 characters (3.5 digits)2. PN junction measurement range: 0.00-2.993. Charging voltage: 5V4. Current: 300mA5. Battery capacity: 250mAh6. Screen size: 1.77 inch7. Size: about 7.4 x 3.6 x 1.4cm8. Weight: about 25gFeatures:1. Supports Type-C/8 Pin device detection for mobile phones and computers2. Intelligent automatic detection, turn off the mobile phone, press the power button to turn on the product, connect to the tail port of the mobile phone, and the device to be detected will start automatic detection. Press the corresponding interface button of the product to re-test3. Automatically lock the charging fault point. The instrument can automatically read the diode characteristic value of the corresponding USB interface, and then diagnose and locate the fault problem of the USB interface based on the value4. High-definition display, small screen with multiple information display, and full view of the measured values 5. The instrument does not respond to key operations during the detection process, and automatically shuts down after 2 minutes of no operation6. The detection value 0.00 indicates a short circuit/OL indicates an open circuit/the detection value is red, indicating that the PN value is abnormal
