2. precautions

  • When the colorimeter has not been used for a long time, it is recommended to perform calibration before using.

  • Please ensure that the sample is evenly colored with a flat and clean surface, otherwise it will affect the measurement accuracy.

  • After the base is removed from the host, it should be stored in a clean place to avoid contamination of the standard tile.

  • Do not insert any object inside the colorimeter to clean it, as this will damage it and affect measurement accuracy and operational safety.

  • Charge the colorimeter in time when the battery is out of power.

  • If not in use over 6 months, charge it regularly to prevent the battery from over-discharge and damage.

  • It's recommended to calibrate the instrument once each year. And we offer calibration service.

  • Due to different mobile phone displays, there may be a slight color difference between the actual color and the color displayed on the mobile phone App.
