feature: 1. 2.5Msps high-speed sampling, 1MHz analog bandwidth (ACV oscilloscope only), 4000 code digital multimeter. 2. One-key oscilloscope, there are three waveform scanning modes: Auto/Normal/Single. 3. The data waveform retention function during measurement can store 100 sets of data and 10 waveforms. 4. These 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. 6. The functions of the multimeter include DC/AC voltage/current, resistance, capacitance, frequency, duty cycle, diode/continuity test. 7. Automatic/manual range switching, real-time data and stored data are displayed on the same screen. 8. Overload protection 500mA / 10A double fuse, double protection meter. 9. Automatic sleep function, no operation for 15 minutes. 10. Adopting 2.4-inch color screen display, the display effect is clear. 11. Panel calibration, memory calibration coefficients do not need potentiometer adjustment, which is more reliable. specification: Instrument characteristics and technical parameters: 1.
