Made of fine quality material, practical, easy to operate and use, wide application range, has a long service life. Features: Oscilloscope multimeter 2 in 1, improve your work efficiency. One-button oscilloscope: no need oscilloscope probe, measuring waveform directly. Fast and accurate measurement, clear waveform display. 240*320 color screen: the color display is clearer, and the secondary display at the bottom provides more function menus. Multimeter measurement functions: AC/DC voltage, AC/DC current, resistance, capacitance, frequency, duty cycle, diode test, continuity test. Storage: mass storage, 100 data/10 waveforms. Triple safety: double insurance tube, 500mA/250V, 10A/250V. Input voltage is greater than 24V, beep warning once. Input over range, beep warning. Same screen display: historical records and real-time data are displayed on the same screen for easy comparison and analysis of data. Buttons and dial: silicone button, sensitive pressing function dial, accurate gear. Back bracket: the back bracket is tilted at 60° for easy viewing.
