Multifunctional design, with AC voltage, DC voltage, AC current, DC current, resistance and capacitance test function. Dual channel oscilloscope function with 50 MHz bandwidth and 280 MS sampling rate. Built-in waveform signal generator with automatic waveform measurement and recognition function, there is no need to clearly display the measured signal waveform without the measured signal waveform. Characteristics: (Highest quality material): ABS silicone case, resistant to drops and shocks. The circuit board uses expensive immersion gold process, characterized by high resistance to antioxidant corrosion, stable working performance and high reliability. (3-in-1 design with 3,5-inch) color display: This product brilliantly integrates the functions of a digital oscilloscope, multimeter and signal generator into one device. 3,5 inch color display, screen readings are clearer and image colors richer. Data visualization design, user-friendly interface and operating mode, so that users do not have to spend a lot of time studying to quickly start working, improve work efficiency. (Signal generator): Equipped with we built-in signal generator function, with automatic waveform measurement and recognition function, there is no need to clearly display the measured signal waveform without the measured signal waveform. (High precision multimeter): High precision multimeter with True RMS measurement function. It supports DC voltage, AC voltage, DC current, AC current, resistance and capacitance test. (Digital oscilloscope) function: The real-time sampling rate of the oscilloscope is up to 280 MS/s, allowing you to capture more signal details and provide more accurate measurement results. The 50MHz band can meet the testing needs of most electronic devices, you can easily cope with both high and low frequency signals. More oscilloscope functions including overclocking function, glow mode and XY mode, making measurements more cost-effective. The built-in high voltage protection module can effectively prevent the oscilloscope from being damaged by high voltage currents caused by improper use or equipment failure, improving the service time and safety of the equipment. (Saving waveforms and screenshots): Multiple waveform measurements for everyday needs and functions for saving waveforms and screenshots. Press and hold the SAVE button for 2 seconds to take a screenshot and save it to display the image in full screen and perform a secondary analysis of the saved waveform data for secondary analysis, or connect it to your computer za using the USB cable and access the saved waveforms. (Wide Applications): It can easily perform measurements in various fields and is widely used in testing and debugging electronic circuits, troubleshooting and repairing electronic components.
