Spectrum Calibration Improve measurement accuracy with the new calibration feature. Place any white reflective surface in front of the camera, tap "Calibrate," and run a single reference scan. All future scans are automatically normalized against this baseline, removing brightness variations caused by the light source across different wavelengths. This results in cleaner, more consistent spectrum readings where intensity differences reflect actual material properties rather than LED output characteristics. • One-tap calibration with on-screen guidance • Calibration persists between sessions • Recalibrate or clear anytime • Visual indicator shows calibration status
