This handheld instrument combines a 20MHz, single-channel, digital oscilloscope for viewing electrical signals with a manual/auto range digital multimeter for measuring AC voltage to 750V and DC voltage to 1000V, AC/DC current to 20A, resistance to 40MΩ, and capacitance to 100μF. The oscilloscope has maximum real-time sampling rate of 80MS/s and record length of 12.8div. The multimeter has two ranging modes: manual--allows the user to select the operating range; and auto--automatically selects the appropriate operating range. With USB port, user can start the communication between the meter and PC and upload all data or waveform to PC. Features:Professional digital oscilloscope with 1CH, 80MS/s Max. sampling rate and 20MHz bandwidth.Digital multimeter functions include True RMS DC/AC voltage/current, resistance, capacitance, frequency, duty cycle, diode and continuity test.3.3 Inch large LCD display with white LED backlight, easy and clear for reading. Full auto set up for volt/div and time/div of DSO.DSO Trigger modes: Automatic, Normal, Single.DSO Auto Measurement: Vpp, Vavg, Vrms, dBm.DSO Cursor readout: dV, dt, 1/dt(frequency).Screen hold function.Save and recall up to 100 groups of waveform and data. User can start the communication between the meter and PC via USB interface.Auto power off: 5~60 minutes adjustable. Built-in 3.7V 800mAh Li-ion battery(included), convenient for use and charging.Comes with a protective soft shell, providing good protection for the instrument.Specifications:Digital Storage Oscilloscope:Bandwidth: DC~20MHz(50mV/div ~ 10V/div)Max.
