Features: Innovative PD Tester: Adopting the touching button control technology, adding G-sensor automatic screen rotation technology, as well as battery capacity calculation, MAX maximum parameter recording, electrical parameter curve display, and other features, and also increasing the measurement voltage to 48V of PD3.1 protocol, current up to 13A (short-time peak), making the meter measurement value compatibility wider. Touching Button & G-sensor Auto Screen Rotating Display: Adopting the touching button control, easy to switch between different interfaces, providing high sensitivity and reliability, improving the controllability and application lifetime. Built-in internal acceleration G-sensor, adapts to the user test in 4 orientations, when the display will automatically display the screen in the positive direction for the user to view, providing a better user experience. Multi-function display: Adopts digital color display, supports current, voltage, power, capacitance, capacity, time, temperature, maximum current, maximum voltage, maximum power, current, and voltage curve display, and supports language selection between Chinese and English. PD3.1 Protocol 48V High Voltage Measurement: Widely compatible with PD3.1 48V high voltage protocol, the Type-C port is compatible with all power-on test protocols, such as PD2.0, PD3.0, PD3.1, QC2.0, QC3.0, SCPAFC, PE, DASH VOOC, SuperVOOC and so on. It automatically rests the screen when there is no power, low power consumption design, is energy saving, and eco-friendly, prolonging the service lifespan of the screen. Internal Battery Capacity Calculation: Using the internal battery capacity calculation logic algorithm display interface, based on the step high-voltage charging power quasi-value data for the battery voltage and conversion efficiency of the logic of the software calculations, completely circumvented due to the high-voltage test can not be tested within the battery capacity of the shortcomings of the machine, to accurately determine at the value of the internal battery capacity of the device. Logic algorithm displayed by measuring a variety of rechargeable treasures and different types of battery capacity. Electric Parameter MAX Maximum Measurement Recording: The charging process increases the maximum test data recording function, the user can unattended view the charging process of the maximum voltage value, maximum current value, and maximum power value, so you can easily know the mobilephone charging size. It can test all kinds of type-C rechargers and data cables. Real-time Voltage and Current Curve Display: With real-time voltage and current curve display function, it is convenient for users to analyze the fluctuation status during the charging process, and in the process, you can also pause and continue by quickly touching the inductive point, which is more convenient to query the curve status for a period of time quietly. Bi-directional Measurement & Offline Storage: Supports bi-directional current measurement technology, can be plugged into the recharger and cellphone measurement, with no-load current clearing function, making the current measurement more accurate. Supports ROM offline storage of power failure memory data, convenient for the data accumulation application of the batterylife test, so that the accuracy of the power capacity test is greatly improved. Supports laptop charging check function, real-time check of charging voltage/current function, and other points of a variety of parameter information, compatible with the measurement of the high-power laptop, detecting the degree of battery aging.
