4.1 Oscilloscope Mode

In Oscilloscope mode, the device displays real-time waveforms, allowing for detailed analysis of electrical signals.

• Selecting Channels: Press the CH1/2 key to toggle between Channel 1 and Channel 2, or to display both simultaneously.
• Auto Setting: Press the Auto key for automatic adjustment of vertical and horizontal scales and trigger settings to display a stable waveform. This is useful for quick signal acquisition.
• Manual Adjustments: Use the navigation keys to adjust vertical sensitivity (Volts/Div), horizontal time base (Sec/Div), and trigger level.
• Measurements: Press the Measure key to access automatic measurement functions. The device supports 7 types of automatic measurements (e.g., Vpp, Vmax, Vmin, Freq, Period, Duty Cycle).
• Run/Stop: Press the Run/Stop key to pause or resume waveform acquisition.

4.2 Multimeter Mode

In Multimeter mode, the device functions as a digital multimeter for measuring voltage, current, resistance, capacitance, and continuity.

• Function Selection: Use the navigation keys or dedicated function keys (if available) to select the desired measurement function (e.g., DC Voltage, AC Voltage, Resistance).
• Auto Ranging: The Auto key can be used to enable or disable auto-ranging for most measurements.
• Connecting Leads: Connect the test leads to the appropriate input jacks for the selected measurement.
• Reading Measurements: The measurement value will be displayed on the screen.

4.3 Signal Generator Mode

The built-in signal generator can output various waveforms for testing circuits.

• Waveform Selection: Select the desired waveform type (e.g., Sine, Square, Triangle) from the menu.
• Parameter Adjustment: Adjust parameters such as frequency, amplitude, and offset using the navigation keys.
• Output Connection: Connect the output of the signal generator (GEN Out) to the circuit under test.

4.4 PC Connection

The USB Type-C interface allows connection to a computer for data transfer and remote control. Refer to the manufacturer's website for specific software and driver requirements.
