Innovation patent description-Auto White Calibration
It’s an easy, simple and fast auto white calibration technology at startup which can escape from the traditional complex manual white and black calibration.
When I start up the colorimeter, it will complete white and black calibration without any consciousness. That’s really convenient!
Unlike the old colorimeter, I have to operate many times to enter measurement status.
