6. Maintenance
6.1 Cleaning
Regularly clean the device, especially the measurement aperture and the whiteboard on the calibration base. Use a soft, dry cloth. For stubborn dirt, a slightly damp cloth with mild detergent can be used, followed by drying. Do not use abrasive cleaners or solvents.
6.2 Storage
When not in use, store the spectrometer in its original packaging or a protective case in a cool, dry place, away from direct sunlight and extreme temperatures.
6.3 Calibration
Perform whiteboard calibration before each measurement session or if the device has been moved or subjected to significant temperature changes.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low battery or power button not pressed correctly. | Charge the device. Press and hold the power button for a few seconds. |
| Inaccurate measurements. | Device not calibrated, dirty aperture/whiteboard, or incorrect measurement technique. | Perform whiteboard calibration. Clean the aperture and whiteboard. Ensure proper contact with the sample. |
| Cannot connect to SQCX software. | USB cable issue, software not installed, or driver problems. | Check USB connection. Reinstall SQCX software and drivers. |
| Screen is unresponsive. | Software glitch or temporary freeze. | Restart the device by holding the power button. If issue persists, contact support. |
