6. Troubleshooting

If you encounter issues with your FNIRSI 2D15P, please refer to the following common troubleshooting steps:

• Device not powering on: Ensure the battery is sufficiently charged. Connect the device to a power source using the USB Type-C cable and try again.
• Inaccurate measurements: Perform an automatic calibration. Check probe connections and ensure they are securely attached. Verify that the correct measurement mode and range are selected.
• No waveform display: Check probe connections to the circuit under test. Ensure the trigger settings (mode, level, type) are appropriate for the signal being measured. Adjust vertical and horizontal scales.
• Screen unresponsive: If the touch screen is unresponsive, try using the physical buttons and rotary encoder. If the device is completely frozen, perform a hard reset by holding the power button for an extended period (e.g., 10-15 seconds) until it powers off, then restart.
• Signal generator not outputting: Ensure the signal generator mode is active and the output is enabled. Check the frequency, amplitude, and duty cycle settings. Verify the connection to the circuit under test.
