Oscilloscope ProbesProduct DescriptionInput voltage: 3V-9VOutput voltage: 3V-9VVoltage Resolution: 0.01VInput current: 0A-5A (recommended use range 0-3A)Output current: (recommended use range 0-3A)Current resolution: 0.01AAccuracy: 1%Line Loss: 0.1 ohmsLeft and right test content: voltage, currentCommunication function: yesData calibration function: yesSize: 60.5*28*15*12.7mmMeasuring range: DC 3V-9V, current: 0-3A (error: 1%) maximum support 5A5A current, (after more than 3A, the error will be larger by 3%). Packing: anti-static bagThe USB voltmeter and ammeter can easily measure the output voltage of the USB port and the working current of the device! (Please note: it can only display the real-time working voltage and current of the electrical appliance, and does not have the function of a discharge meter, that is, it cannot be set A certain voltage and a certain current to discharge! Small size, no power supply and other auxiliary equipment, plug and play! It also detects the charging current and voltage of any USB charger (computer USB, home charger, car charger), to This judges whether the performance of the charger and the performance of the charging cable meet the requirements! It has a wide range of applications, any mobile phone, any electronic product, can be used, easy to operate, suitable for factories, exhibition demonstrations, laboratories and users!Features:1. This product can measure the voltage of the USB power supply equipment when it is empty and loaded, and the voltage and current of the USB terminal equipment when it is working.2. Current and voltage cycle display, easy to use and practical.3. Small and easy to carry, no need to connect another power supply and display voltage and current data at the same time, easy to viewCan detect a variety of power supply output voltages and currentsDetectable USB cable qualityWith precision
