සැලසුම
මූලික පරීක්ෂාව
Before first use, carefully inspect the refractometer for any signs of damage that may have occurred during shipping. Ensure the prism surface is clean and free of dust or debris.
ක්රමාංකනය
The MASTER-53α features Automatic Temperature Compensation (ATC), which adjusts readings for ambient temperature variations. However, periodic calibration is essential for accuracy.
- Ensure the prism surface is clean and dry.
- Apply a few drops of distilled water onto the prism.
- Close the daylight plate gently.
- Look through the eyepiece and observe the boundary line.
- Using the provided calibration screwdriver (or a suitable alternative), turn the calibration screw until the boundary line aligns precisely with the "0" mark on the Brix scale.
- Clean the prism thoroughly after calibration.
Note: The unit retains its water-resistance even when the calibration screw is adjusted.

මිනුම් ක්රියා පටිපාටිය
- Ensure the prism and daylight plate are clean and dry.
- Using the spoon-shaped tip, apply a small volume (approximately 10µl or more) of the sample onto the main prism surface. The spoon-shaped tip facilitates automatic sample distribution (ASD).
- Gently close the daylight plate over the sample, ensuring no air bubbles are trapped. The sample should spread evenly across the prism.
- Point the refractometer towards a light source (ambient light is sufficient; no external power source is required).
- Look through the monocular, focusable, cushioned eyepiece.
- Adjust the focus of the eyepiece until the scale and boundary line are clear.
- Read the value where the boundary line intersects the Brix scale. The bright, high-contrast display ensures clear visibility.
Understanding Readings
The Brix scale indicates the sugar concentration in percent by weight (% Brix). Due to the Automatic Temperature Compensation (ATC) feature, the displayed reading is automatically corrected for temperatures between 10°C and 30°C, providing accurate results without manual temperature adjustments.
නඩත්තු කිරීම
පිරිසිදු කිරීම
Regular cleaning is crucial for maintaining accuracy and hygiene. The MASTER-53α is IP-65 rated (excluding the eyepiece), meaning it is dust-tight and protected against water jets. This allows for easy cleaning:
- After each use, clean the prism and daylight plate immediately with a soft, damp රෙදි හෝ පටක.
- For thorough cleaning, the unit can be rinsed under running water from a faucet. Ensure no water enters the eyepiece.
- Avoid using abrasive materials or harsh solvents, as these can damage the prism or body.
- The smooth outer shell grip is designed to be easy to clean, reducing the possibility of food and sample entrapment and preventing bacterial growth.

When not in use, store the refractometer in its protective plastic storage case. The foam cut-out insert provides cushioning and protects the instrument from physical damage and environmental factors. Store in a cool, dry place away from direct sunlight and extreme temperatures.
