   • Wipe the prism clean with a soft cloth.

Operating Instructions

1. Sample Preparation: Ensure the sample is homogeneous and free of air bubbles or solid particles.
2. Applying Sample: Place 2-3 drops of the sample onto the prism surface. Ensure the sample covers the entire prism.
3. Taking a Measurement:
   • Press the START button.
   • The measurement will be displayed in approximately three seconds.
   • The device automatically compensates for temperature variations (ATC).
   • If "ELI" (External Light Interference) is displayed, move the device away from direct light sources and re-measure.
4. Cleaning After Use: Immediately after each measurement, clean the prism thoroughly with distilled water and a soft, lint-free cloth. Do not use abrasive materials or solvents.

Maintenance

• Cleaning: Regularly clean the prism and the body of the refractometer. The device is water-resistant (IP65), allowing for rinsing under a tap, but avoid submerging it.
• Storage: Store the refractometer in its plastic storage case in a cool, dry place, away from direct sunlight and extreme temperatures.
• Battery Replacement: Replace batteries when the low battery indicator appears on the display. Always use fresh AAA batteries.
• Calibration: Perform zero calibration with distilled water regularly, especially if the device has been stored for a long time or if readings appear inconsistent.
