Setup Guide
1. Initial Charging
Before first use, fully charge the device. Connect the provided USB cable to the Type-C port on the device and the other end to a standard USB power adapter (not included) or a computer USB port. The charging indicator will illuminate during charging and turn off when fully charged. A full charge typically takes approximately 3-4 hours.
2. Powering On/Off
To power on the device, press and hold the power button located on the side until the screen illuminates. To power off, press and hold the power button again until the device shuts down.
3. Basic Navigation
The device features a full touchscreen for most operations. Additionally, a function wheel is provided for precise adjustments and menu navigation. Rotate the wheel to scroll through options and press it to confirm selections.
Operating Instructions
1. Oscilloscope Mode
The oscilloscope function allows for the visualization and analysis of electrical signals over time.
- Connecting Probes: Connect the oscilloscope probes to the BNC connectors labeled "OSC 1" and "OSC 2" on the top of the device. Ensure a secure connection.
- Probe Calibration: For accurate measurements, it is recommended to calibrate the probes before use. Refer to the on-screen menu for probe calibration options.
- Selecting Channels: Use the touchscreen to select the desired input channel (CH1 or CH2).
- Adjusting Parameters:
- Vertical Scale (Volts/Div): Adjust the voltage per division to fit the waveform vertically on the screen.
- Horizontal Scale (Time/Div): Adjust the time per division to view the waveform's period or frequency.
- Trigger Settings: Set the trigger level, slope, and mode (Auto, Normal, Single) to stabilize the waveform display.
- Measurement Functions: The device can automatically measure various waveform parameters such as Vpp (peak-to-peak voltage), Vmax, Vmin, Vavg, RMS, Frequency, and Duty Cycle. Access these measurements via the on-screen menu.
- Waveform Saving: Use the save function to store waveform data for later review or transfer to a computer.
2. Signal Generator Mode
The built-in signal generator can produce various waveforms for testing circuits.

- Accessing Signal Generator: Navigate to the signal generator mode from the main menu.
- Connecting Output: Connect the signal generator output lead to the designated port on the device.
- Selecting Waveform Type: Choose from available waveform types (e.g., Sine, Square, Triangle, Sawtooth).
- Setting Frequency: Adjust the output frequency from 0Hz to 2MHz using the touchscreen or function wheel.
- Setting Amplitude: Adjust the output amplitude from 0.1V to 3.0V.
- Outputting Signal: Activate the signal output to generate the configured waveform.
3. Multimeter Mode
The multimeter function provides standard electrical measurements.
- Connecting Test Leads: Connect the red and black multimeter test leads to the appropriate input jacks on the device.
- Selecting Measurement Function: Use the touchscreen to select the desired measurement function (e.g., DC Voltage, AC Voltage, Resistance, Continuity, Diode Test).
- Performing Measurement: Apply the test leads to the circuit or component under test according to standard multimeter practices. The measurement will be displayed on the screen.
4. Data Management and PC Connection

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low battery or completely discharged. | Connect the device to a power source using the USB cable and allow it to charge for at least 30 minutes before attempting to power on again. |
| No waveform displayed in Oscilloscope mode. | Probe not connected correctly; incorrect trigger settings; signal too small or too large. | Ensure probes are securely connected. Adjust trigger level and mode. Adjust vertical (Volts/Div) and horizontal (Time/Div) scales to match the input signal. |
| Signal generator output is incorrect or absent. | Incorrect frequency/amplitude settings; output lead not connected. | Verify frequency and amplitude settings. Ensure the signal generator output lead is properly connected to the device and the circuit under test. |
| Touchscreen unresponsive. | Temporary software glitch; screen dirty. | Restart the device. Clean the screen with a soft, dry cloth. If the issue persists, contact customer support. |
| Cannot connect to PC. | Faulty USB cable; incorrect PC settings; missing drivers. | Try a different USB cable. Ensure the device is in PC connection mode (if applicable). Check PC device manager for driver issues and install necessary drivers from the manufacturer's website. |
