4. Closed the shading plate clockwise.
5. Press the “On|Off/Read”shortly, or touch the “touch instruction point”. The screen shows the value of BRIX. Press the “Zero” shortly, The screen will show the value of Refractive index.
Zero point calibration
1, Use the pure water to clean the detection slot with soft cloth repeatedly.
2, Add 3-5 drops of pure water to the detection slot.
3, Press and hold the“Zero”, until the screen shows “ zeroing”, release the button and start.
