Feature:1. Concise Appearance: Compact and portable body, with a simple and elegant appearance, easy to carry, does not occupy the space, say goodbye to the traditional bulky and difficult to carry. With silicone protective cover for safer use. Folding stand design on the back, convenient for testing, practical to use.2. 3in1 Design: This product ingeniously integrates the functions of a digital oscilloscope, electrical test pen, and multimeter into one device. It can detect whether the circuit is powered, simultaneously measure a variety of electrical parameters or capture waveforms, and display the electrical parameters or waveforms of electrical signals.3. Digital TFT Display: With clear definition 2.8inch TFT color display, higher accuracy, large screen display readings at a glance. Applicable to various measurements under complex environments, greatly enhances the reading experience. Suitable for middle-aged and elderly electricians to use, easy to operate.4. High-precise Multimeter: 6000 counts True RMS multimeter, that supports the measurement of voltage, current, resistance, capacitance, diode, frequency, etc. And with the data hold function.5. Digital Oscilloscope Function: With 10MHz bandwidth, 48NSa/S real-time sampling rate, auto-tuning measurement waveform display with voltage/time base, shift, trigger, and coupling (DC/AC) functions, to meet the waveform capture needs of different users. No complicated operation, you can quickly detect and display the waveform. 3V 1KHz standard squarewave output, 64KB waveform storage depth, a total of 24 pictures can be stored.6. Electrical Test Pen: It can be used to detect whether the circuit is energized or not, with dual-sensitive electric pen mode, inductive, and contact electric pen mode, which is very convenient for circuit maintenance and testing.7. Data Storage: The multimeter interface is intuitive and simple, one screen with four data displays, supports Chinese and English interface switching, can be saved as a screenshot, can also be exported through the USB imaging export, and can be restarted at any time. Support firmware upgrades.8.
