1. Hyrje
This manual provides detailed instructions for the proper use, calibration, and maintenance of your Geko G02662 Freezing Point Refractometer. This precision optical instrument is designed to measure the freezing point of automotive coolants (ethylene glycol and propylene glycol based) and battery fluid condition. Please read this manual thoroughly before operating the device to ensure accurate results and prolong its lifespan.
2. Informacion mbi sigurinë
- Always handle the refractometer with care. Avoid dropping or subjecting it to strong impacts.
- Do not immerse the instrument in water or other liquids.
- Avoid direct exposure of the prism to strong light sources, as this may damage the optical components.
- When handling automotive fluids, wear appropriate personal protective equipment (e.g., gloves, eye protection) and follow manufacturer safety guidelines for the fluids being tested.
- Keep the instrument out of reach of children.

- okular: I përdorur për të view the measurement scale. Rotate to adjust focus.
- Kapje gome: Provides a secure hold.
- Trupi kryesor: Contains the optical system.
- Calibration Screw: Used to adjust the zero point (under a cap).
- Prizma: The surface where the sample is placed.
- Pllaka e mbulimit: Covers the sample në prizëm.
5. Konfigurimi
Before first use, or if the focus appears blurry:
- Hold the refractometer towards a light source.
- Shikoni përmes okularit.
- Rotate the eyepiece (part 1 in Figure 1) until the scale is clear and in sharp focus.
6. Udhëzimet e funksionimit
Follow these steps to take an accurate measurement:
- Clean the Prism: Ensure the prism (part 5) and cover plate (part 6) are clean and dry using the provided cleaning cloth.
- Aplikoni Sampe: Open the cover plate. Using the pipette, place 2-3 drops of the liquid to be tested onto the main prism.
- Close Cover Plate: Gently close the cover plate so that the liquid spreads evenly across the entire surface of the prism without air bubbles.
- Wait for Temperature Equalization: Allow approximately 30 seconds for the sample to equalize to the instrument's temperature. This is crucial for accurate readings.
- Lexoni matjen: Hold the refractometer towards a light source and look through the eyepiece. The boundary line between the blue and white fields will indicate the measurement on the appropriate scale.
- Pastroni pas përdorimit: Immediately after each measurement, clean the prism and cover plate thoroughly with a damp cloth, then dry with the cleaning cloth. Failure to do so can lead to inaccurate readings and damage to the prism.
7. Kalibrimi
Calibration should be performed before first use, after cleaning, or if you suspect inaccurate readings. Use distilled water for calibration.
- Ensure the refractometer is at room temperature (20°C / 68°F).
- Clean the prism and cover plate thoroughly.
- Place 2-3 drops of ujë të distiluar onto the prism. Close the cover plate.
- Wait 30 seconds for temperature equalization.
- Look through the eyepiece. The boundary line should align with the 'WATERLINE' or '0' mark on the scale.
- If it does not, use the provided mini-screwdriver to turn the calibration screw (part 4, usually under a small cap) until the boundary line aligns perfectly with the 'WATERLINE' or '0' mark.
- Clean and dry the prism and cover plate.
8. Mirëmbajtja dhe Kujdesi
- Pastrimi: Always clean the prism and cover plate immediately after use with a soft, damp cloth, then dry with the cleaning cloth. Do not use abrasive materials or solvents.
- Magazinimi: Store the refractometer in its protective case in a dry, cool, and dust-free environment when not in use. Avoid direct sunlight or extreme temperatures.
- Shmangni dëmtimet: Do not touch the prism surface with your fingers or any hard objects.
9. Troubleshooting
| Problem | Shkaku i mundshëm | Zgjidhje |
|---|---|---|
| Blurry scale | Eyepiece out of focus | Rotate the eyepiece to adjust focus. |
| Lexime të pasakta | Instrument not calibrated; Prism dirty; Insufficient sample; Air bubbles in sample; Temperature difference. | Calibrate the instrument; Clean the prism; Apply sufficient sample (2-3 drops); Ensure no air bubbles; Allow sample to equalize temperature. |
| Boundary line not visible | Insufficient light; Sample too dark/opaque. | Point towards a brighter light source; Ensure sample is clear enough for measurement. |
