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 “Settings” (It is the icon in the upper left hand-side of the app) and then going into the “Manage Device” section.

After calibration is complete, remove the end 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.
