In the product box, the PC software is installed in USB flash disk.
Download "colorimeter-windows-V1.0.0.rar" to the local and run it directly after decompression.
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.
