1. 2.5Msps high-speed sampling, 1MHz analog bandwidth (only ACV oscilloscope), 4000 code digital multimeter. 2. One-key oscilloscope, there are three waveform scanning modes: auto/normal/single. 3. Data waveform retention function during measurement can store 100 groups of data and 10 waveforms. 4. The parameters can be set independently during waveform measurement, such as time base, amplitude, waveform scan mode, etc. 5. Relative value measurement can effectively eliminate lead resistance, distributed capacitance or interference signals. Multimeter functions include DC/AC voltage/current, resistance, capacitance, frequency, duty cycle, diode/continuity test. Automatic/manual range switching, real-time data and stored data are displayed on the same screen. Overload protection 500mA/10A double fuse, double protection meter. Automatic sleep function without operation for 15 minutes. Adopt 2.4 inch color screen display, the display effect is clear. Panel calibration, memory calibration coefficients do not need potentiometer adjustment, higher reliability color: Black Material: PC Package Contents: 1 x ET828 Oscilloscope Multimeter Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
