Feature:1. The instrument can monitor USB voltage, current, capacity, electric quantity, power, load impedance, D+/D voltage, charging time and other data.2. This USB tester is compatible with TypeC pd fast charging protocol 45W power supply and for ios 87W smart charger PD power supply (such as mobile power supply).3. Compatible for Qualcomm QC2.0 (5V/9V/12V/20V), for Qualcomm QC3.0 (3.812V +/ 0.2 step), for Android BC1.2 (5V), for ios 5V/2.4A and for MTKPE (5V/7V/9V/12V), for Qualcomm fast charging protocol voltage passthrough measurement range.4. Like the front and back pass mode of the USB internal data line, the tester can also be compatible with U disk readings and computer USB interface data transmission5. The measurement application of voltage and current has a wider range of use, and the USB interface can be used. Also support OTG function.Specification:Item Type: USB Digital TesterMaterial: ABSSize: Approx. 61x68x10.8mm/2.4x2.7x0.4inVoltage Measurement Range: 3.6V-32.0VVoltage Measurement Accuracy: 0.01VCurrent Measurement Range: 0.00-5.10ACurrent Measurement Accuracy: 0.01AAccumulated Capacity Range: 0-99999mAhAccumulation Accuracy of Capacity 0.001AhPower Accumulation Range: 0-999999mWhAccumulated Power Accuracy: 0.001WhPower Measurement Range: 000.00-150.00 WPower Measurement Accuracy: 0.01WImpedance Measurement Range: 1-999.9Impedance Measurement Accuracy: 0.1Temperature Measurement Range: 0-80Temperature Measurement Accuracy: 1Longest Timing: 999 Hours, 59 Minutes, 59 SecondsTiming Accuracy: 1 SecondTimed Charging Reminder: 24 Hours Countdown, Arbitrary Set ValueUSB D+ Voltage Range: 0V-2.999VUSB D+ Voltage Accuracy: 0.001VUSB D- Voltage Range: 0V-2.999VUSB D- Accuracy: 0.001VThe Complete Charger Reminder Parameters of the Mobile Phone: <2W/0.5 HourRefresh Time: 500mS/TimeMeasuring Speed: 0.5 Times/SecAlarm Mode: Siren + Display PromptSelf-Consumption Flow: <0.02AWorking Temperature: -10 to + 60Working Humidity: 10-80%RHWorking Pressure: 80-106kPaHow to Use:1.
