Provides automatic, normal, and single scan modes to easily observe signal changes, and supports one-click waveform viewing real-time display, allowing users to quickly capture and analyze signals. It has relative value measurement function, which can effectively lead resistance, distributed capacitance or interference signals.Equipped with dual fuses (500mA and 10A), it provides dual overload protection to the safety and stability of the equipment. The data waveform is maintained during the measurement process, and 10 data sets and 10 waveforms can be stored for analysis and comparison.When measuring waveforms, users can freely adjust parameters such as time cardinality, amplitude, scanning mode, etc. With 2.5Msps high-speed sampling and 1MHz analog bandwidth (limited to the ACV mode of the oscilloscope), a built-in 4000 counting digital multimeter, supports DC/AC voltage, current, resistor, capacitance, frequency, duty cycle and diode testing, providing comprehensive measurement capabilities. Includes a 2.4-inch color display, which is clearly visible and supports automatic sleep mode (after 15 minutes of disabling).With panel calibration, memory calibration coefficients are not required for potentiometer adjustment, improving device reliability and making it easy to carry and use anywhere., Manufacturer: Akfldms
