5. Setup

5.1 Initial Charging

Before first use, fully charge the device using the provided USB Type-C cable and power adapter. The charging indicator will show the charging status.

5.2 Power On/Off

Press and hold the Power Switch Key (usually marked with a power symbol) to turn the device on or off.

5.3 Language Selection

Upon first startup, the device may be in a default language. To change the language:

1. Press the System key.
2. Navigate to the language settings (often labeled F2 or similar).
3. Select your desired language (e.g., English) using the navigation keys and confirm.

5.4 Oscilloscope Probe Calibration

For accurate oscilloscope measurements, calibrate the passive probe before use:

1. Connect the oscilloscope probe to the BNC input connector on the bottom of the device.
2. Connect the probe tip to the probe compensation/signal generator output connector (1KHz square wave) on the top side of the device.
3. Enter Oscilloscope mode (if not already there) and adjust the vertical and horizontal scales to view the square wave.
4. Using the small calibration tool, adjust the screw on the probe connector until the square wave displayed on the screen has flat tops and bottoms with sharp corners, indicating proper compensation.

6. Operating Instructions

6.1 Switching Modes

Press the Mode key to cycle between Oscilloscope, Multimeter, and Waveform Generator functions.

6.2 Oscilloscope Operation

In Oscilloscope mode, the device displays waveforms over time. Use the following controls:

  • Adjust the vertical (Volts/Div) and horizontal (Time/Div) scales.
  • Check trigger settings; try setting the trigger mode to 'Auto' or adjusting the trigger level.
  • Ensure the 'Run' state is active (not paused).
• Multimeter readings are inaccurate or slow:
  • Ensure test leads are securely connected to the correct input ports.
  • Verify the correct measurement function and range are selected.
  • For continuity tests, allow a moment for the device to register the connection, as some users have noted a slight delay.
  • Consider performing a factory reset via the System menu if persistent issues occur.
• Waveform generator output is incorrect:
  • Ensure the output is connected to the correct port.
  • Verify the selected waveform type, frequency, and amplitude settings.
