Calibration will be prompted at every device/app connection. If the app does not automatically ask you to calibrate your device, you can manually initiate this action by going to "Manage Device-Connected Colourpin" in the Settings by pressing the user icon on the top right corner.
After calibration is complete, remove the calibration cap, screw it onto the back of your device, and then you're ready to scan.
When not using your Colourpin device, keep the calibration cap attached to the device for lens protection. In addition, it is important to keep the calibration cap as clean as possible to ensure the highest level of accuracy when scanning colours.
If your calibration cap has become damaged (miscoloured, scratched) or if you have lost your calibration cap, you can order a new calibration cap from the NCS Colour Webshop.
