1. Display voltage, current, power, mAh, mWh 2. the menu button to transfer to the recording interface, which can be set to store data of different capacities and energy 3. Every stored data can be deleted and marked. Set the recording interval and maximum capacity 4. Automatic operation rule setting, current threshold setting. End time setting 5. Display information interface. Test circuit resistance function Product Series: POWER-Z Product model: KM001 Product name: Portable USB PD tester Put the wire under test into the tester, and then connect the load, the resistance keep beating until the resistance is stable. The degree is the size of the wire resistance. There is a GOOD evaluation to let you know whether the wire is good or bad. You can set the waveform display refresh rate, the higher the refresh rate, the faster the display Plug in the charger, D+ and D- voltage be displayed automatically, the following figure shows that the charger supports the charging protocol the menu button to automatically trigger the fast charge voltage. Material:plastic colour:Black Package Contents: 1 x Digital Voltage Current Detector Only the above package content, other products are not included. Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
