Operating procedures:
1. Open the cover and clean the detection prism with a soft cloth.
2. Take the test solution, place it on the detection prism, gently close the cover to avoid air bubbles, and make the solution spread over the prism surface and put the instrument into the light plate.
3. Align the light source or the bright area, observe the field of view through the eyepiece, and turn the eyepiece to adjust the handwheel.
4. Make the blue-white boundary of the field of view clear, and the scale value of the boundary is the concentration of the solution.
