Step 3: Calibration of the scanner (two steps)
The scanner lights will indicate when calibration is required, always before scanning a sample. There are two types of calibration scans: Open Air Scan and Calibration Cap Scan (white/yellow background).
1. Open Air Scan
Point the handheld scanner towards the ground, approximately 0.5-1 meter above the surface, and press the "Scan" button (1). Ensure that the glass surface is not covered and avoid pointing at reflective surfaces.
2. Calibration Cap Scan
- White background scan with calibration cap
Before each scan, perform a white background calibration with the calibration cap. Ensure that the sensor head and glass plate are clean from dirt and moisture. If necessary, use the brush and/or tissues to clean them. Place the scanner on the calibration cap with the white side facing up, ensuring that the scanner head is in contact with the white surface. Start the scanning process by pressing the 'scan' button in the app or on the device for one second (2-3).
- Yellow standard scan with calibration cap
If prompted by the application, perform a yellow standard scan using the yellow side of the calibration cap. Turn the calibration cap with the yellow side facing up and position the scanner on the calibration cap. Again, ensure that the scanner head is in contact with the yellow surface. Initiate the scanning process as before.
