Operating Instructions

General Operation

The device features a 2.8-inch HD color screen and intuitive button controls. The main power button is located on the front panel. Navigation buttons (up, down, left, right, enter) are used to select modes and adjust parameters. The 'MENU' button accesses settings, and 'SAVE' allows for waveform screenshot capture.

Oscilloscope Mode

To enter Oscilloscope mode, ensure the appropriate probes are connected to the CH1 and/or CH2 inputs. Use the 'AUTO' button for automatic waveform adjustment. Adjust vertical sensitivity (V/div) and time base (s/div) using the navigation buttons. The device supports various trigger modes (Auto/Normal/Single) and trigger types (Rising edge, Falling edge) for stable waveform display.

• Connecting Probes: Connect the 10X probe or crocodile clip probe to the CH1 or CH2 BNC connectors. Ensure proper grounding.
• Adjusting Parameters: Use the navigation buttons to adjust vertical scale (voltage per division) and horizontal scale (time per division).
• Triggering: Set the trigger level and mode to stabilize the waveform. The 'AUTO' function can quickly set optimal display parameters.
• Waveform Saving: Press the 'SAVE' button to capture a screenshot of the current waveform. Saved images can be reviewed on the device or exported to a computer via USB.

Multimeter Mode

Connect the multimeter test leads to the appropriate input jacks (VΩHz, mA, 10A, COM). Select the desired measurement function (Voltage, Current, Resistance, Capacitance, Temperature, Diode, Continuity) using the mode selection buttons. The device features an autorange function for ease of use.

• Voltage Measurement (AC/DC): Connect leads in parallel to the circuit.
• Current Measurement (AC/DC): Connect leads in series with the circuit. Ensure correct current range (mA or 10A).
• Resistance, Capacitance, Diode, Continuity: Connect leads across the component.
• Temperature Measurement: Use the included temperature probe.

DDS Signal Generator Mode

Connect the DDS output port to the circuit requiring a signal. Select the desired waveform type (sine, square, triangle, etc.), frequency (up to 2MHz), and amplitude (0.1-3.3V) using the device controls. This function is ideal for testing circuits and components.

• Waveform Selection: Choose from 7 available waveform types.
• Frequency and Amplitude Adjustment: Set the desired output frequency and amplitude for the generated signal.

Maintenance

Cleaning

To clean the device, use a soft, dry cloth. For stubborn dirt, a slightly damp cloth with mild detergent can be used. Do not use abrasive cleaners or solvents, as these may damage the casing or screen. Ensure the device is powered off and disconnected from any power source before cleaning.

Battery Care

The device is powered by a built-in 3000mAh rechargeable lithium battery. For optimal battery life, avoid fully discharging the battery frequently. Recharge the device when the low battery reminder appears. If storing the device for an extended period, charge it to approximately 50% and store in a cool, dry place.

Storage

Store the device in a clean, dry environment, away from direct sunlight, extreme temperatures, and high humidity. The device comes with a protective ABS silicone jacket that provides shockproof and drop-proof protection. Always use this protective case during storage and transport to prevent damage.

Troubleshooting

This section provides general guidance for common issues. For detailed troubleshooting steps or issues not covered here, please refer to the comprehensive user manual provided with your product or contact BTMETER customer support.

• Device does not power on: Ensure the battery is sufficiently charged. Connect the device to a power source using the USB Type-C cable and allow it to charge for at least 30 minutes before attempting to power on again.
• Inaccurate Multimeter Readings: Check that the test leads are correctly connected to the appropriate input jacks for the measurement type. Ensure the function mode is correctly selected. Verify that the component being tested is functioning correctly.
• Unstable Oscilloscope Waveform: Adjust the trigger level and trigger mode (Auto, Normal, Single) to stabilize the waveform. Ensure the probe compensation is correctly set if using a 10X probe. Check for proper grounding.
• Signal Generator Output Issues: Verify that the DDS output port is correctly connected. Check the selected waveform type, frequency, and amplitude settings.
• Screen is dim or unresponsive: Adjust the brightness settings in the device menu. If unresponsive, try performing a soft reset by pressing the reset button (if available, typically a small pinhole button).
