4.2 Oscilloscope Function

In oscilloscope mode, the device displays waveforms, allowing for detailed analysis of electrical signals. It offers a 10MHz bandwidth and a 48MSa/s real-time sampling rate.

• Automatic Waveform Capture: Press the AUTO RANGE button (or similar, depending on specific button mapping) for one-key automatic waveform capture, simplifying setup.
• Trigger Modes: Select from three trigger modes: Auto, Normal, and Single. These modes control when the oscilloscope captures and displays a waveform.
• Waveform Data Storage: The device supports storing current waveform data in picture form. This allows for later review or transfer to a PC.
• Square Wave Output: A 3V-1kHz square wave output is available for testing purposes.

4.3 Multimeter Function

In multimeter mode, the device functions as a 9999-count true RMS multimeter, capable of measuring various electrical parameters.

• Voltage Measurement: Measures AC/DC voltage.
• Current Measurement: Measures AC/DC current.
• Resistance Measurement: Measures electrical resistance.
• Capacitance Measurement: Measures capacitance.
• Frequency Measurement: Measures signal frequency.
• Temperature Measurement: Measures temperature using the included thermocouple.
• Diode Test: Checks the functionality of diodes.
• Continuity Test: Checks for electrical continuity in circuits.
