FNB48 PD Type-C USB Power Meter Tester LCD Display Multimeter Voltmeter Ammeter Description Integrated USB-A, Micro-USB, Type-C interface, with 1.77-inch high-definition display, using external 16-bit ADC, PD protocol physical chip, real-time monitoring of voltage, current, power, power, capacity, charging protocol during charging, Curve aveform, etc. No need to match the original data cable, you can also directly detect the charger protocol of OPPO, Huawei, OnePlus and other brands. In any interface, by long pressing the return button, the screen can be hibernated, wake up by any operation, and charging at night will not affect sleep. FNB48 uses the differential pressure method to measure the internal resistance of the cable, Use with constant current load, Easily detect the internal resistance of the cable. Features Voltage and current curve,real-time detection of voltage and current Low-speed voltage and current curve Low speed D+D-curve Record offline curve High-speed voltage ripple(AC coupling) Powerful & Stable performance Protocol detection Protocol trigger Wave curve Line resistance measurement Ultra low internal resistance Driver-free upper computer upgrade Parameter USB3.0 high-speed transmission Monitor voltage: 4~24V Monitor current: 0~6.5A Monitor power: 0~156W Protocol detection A PPLE 2.4A, QC2.0, QC3.0, PD, Sam-sung AFC, Hua wei FCP, Hua wei SCP, VOOC/WARP, Su perVOOC, MTK-PE Protocol trigger QC2.0, QC3.0, Hua wei FCP, Hua wei SCP, Sam sung AFC, PD trigger, VOOC/WARP, SVOOC HIGH PRECISION DISPLAY: 5-digit/6-digit display with one-key switching, max resolution 0.00001, real-time monitoring of subtle changes involtage, current and power during charging. It can also detect the weak current when the original Apple data cable is no-load. FASTER TRANSMISSION RATE WITH USB 3.0: FNB48 uses USB3.0 interface, 9-pin pin design, compatible with USB2.0, transmission rate is 10 times that of USB2.0, and more energy-saving. RECORD MORE DATA: FNB48 can record up to 10 sets of measurement data. It could directly put the calculation formula of battery capacity on the tester, The calculation result is multiplied by 1000 to get the capacity of the battery, and the calculation is more convenient and faster. PD E-MARKER, DASH CABLE INSPECTION: FNB48 supports reading the data of E-Marker and DASH cables. After connecting the data cable, it is easy to read the chips of E-Marker and DASH cables. With analog DASH cable and Apple 2.4A acceleration function, it can directly charge and detect voltage and current without the original data cable. GRAVITY SENSING SCREEN AUTOMATICALLY FLIPS: The screen  OF FNB48 can be flipped freely trough gravity sensing. You can also turn offthe gravity direction recognition, Long press the middle button to realize the screen flip.   Package includes: 1 * FNB48 PD Trigger Voltmeter (Without Bluetooth)
