Multifunctional design, with relative value, data hold, self-calibration function, data storage function, 15W quick charging and etc. Suitable for electric occasions such as automobile maintenance and power maintenance. Features: 3 In 1 Function: This product ingeniously integrates digital oscilloscope, multimeter and signal generator functions into one machine. Digital Oscilloscope Function: Dual channel oscilloscope function, with the real-time sampling rate of 200Msps and bandwidth of 80MHz. With complete trigger function (automatic, single, regular). The trigger slope support selects between Rising, Falling and Double. Set your own parameters such as time base and vertical amplitude during waveform measurement. Multimeter Function: 6000 count auto ranges Ture RMS. Relative value measurement, effectively eliminating wire resistance, distributed capacitance or interference signals. Functions include AC/DCvoltage, AC/DCcurrent, resistance, capacitance, frequency, duty cycle diode, on/off testing. Automatic/manual ranges switching, displaying measurement data and historical data on the same screen. Data waveform hold function during measurement, can store 2000 sets of data, 200 waveforms. Signal Generator Function: 3 kinds of signal waveforms of sinewave, squarewave, trianglewave can be measured. Frequency and amplitude can be set independently. Compact Size & Reliable Quality: Lightweight and portable, also can be used as a portable tool for on-site debugging. Adopts ABS anti-drop housing, anti-slip concave design, high elasticity keys, simple interface, easy operation. 2.8inch Digital TFT Display: 2.8inch color screen, high resolution display with backlight, with bright colors and high contrast, you can see the data clearly. The backlight brightness and the backlight time are adjustable. High Accuracy: Infrared decoding design, quick response, accurate capture of highly sensitive response signal, fast and accurate measurement with small error. Rich Features: Overload protection 500mA/10A double fuse, double protection instrument15 minutes no operation automatic shutdown function. Panel calibration, memory calibration factor without potentiometer adjustment, higher reliability. Folding Bracket: Comes with back bracket, integrated folding, stable placement, free your hands, does not occupy too much space.
