Features:

【Premium Material】: ABS+silicone housing material, drop proof and  shockproof. The printed circuit board adopts high-cost immersion gold process, with high antioxidant corrosion resistance, stable working performance and high reliability.

【3in1 Design with 3.5 Inch Color Display】: This product ingeniously integrates digital oscilloscope, multimeter, and signal generator functions into one device. 3.5-inch color display,  screen readings are clearer, and the visual color is richer. Data visualization design, the user-friendly interface design and operation mode, so that users do not need to spend a lot of time to learn to quickly get started, improve work efficiency.

【Signal Generator】: Equipped with a built-in signal generator function, with automatic waveform measurement and recognition function, no need to display the measured signal waveform clearly without measured signal waveform.

【High-precise Multimeter】: High precise multimeter with true RMS measuring function. Supports the test of DCvoltage, ACvoltage, DCcurrent, ACcurrent, resistance and capacitance.

【Digital Oscilloscope Function】: The real-time sampling rate of the oscilloscope is up to 280MS/s, which can capture more signal details and provide more accurate measurement results. 50MHz bandwidth can meet the testing needs of most electronic devices, both high-frequency and low-frequency signals can be easily coped with. More Oscilloscope functions of overclocking function, afterglow mode, and XY mode, making measurements more cost-effective.

【Intelligent Anti-burning】: Full-grade overload protections, built-in intelligent anti-burn chip, and double ceramic fuses, to prevents the misuse of burn meter, safer to use. The built-in high-voltage protecting module can effectively prevents damage to the oscilloscope from high-voltage currents caused by misuse or equipment failure, improving the service time and safety of the equipment.

【Waveform Save & Screenshot Save】: Multiple waveform measurements for your daily needs, and with waveform save & screenshot save functions. Long press the SAVE button for 2 seconds to take a screenshot and save it in order to view the full screen picture and to makes secondary analysis of the saved waveform data for secondary analysis, or connect it to PC via USB cable access to the stored waveforms.

【Wide Applications】: It can easily handle measurements in a variety of fields and is widely used in the testing and debugging of electronic circuits, troubleshooting and repairing of electronic elements.
