Procedure: 1. Open the cover plate and gently insert the prism with a soft cloth. 2. Take a few drops of the solution to be measured, place them on the prism, and gently close the cover plate to avoid bubbles, ensuring the solution covers the entire surface of the prism. 3. Direct the instrument's light-input plate towards the bright spot of the light source, observe the scene through the eyepiece, and rotate the eyepiece to adjust the handwheel. 4. Ensure the blue-white dividing line in the field of view is clear and that the scale value of the dividing line corresponds to the concentration of the solution. Calibration: Take a few drops of distilled water, place them on the detection prism, turn the zeroing adjustment screw, adjust the position of the dividing line to 0% of the scale, and then wipe the detection prism.
