Geko G02662 Freezing Point Refractometer Instruction Manual

1. መግቢያ

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. የደህንነት መረጃ

• Always handle the refractometer with care. Avoid dropping or subjecting it to strong impacts.
• መሳሪያውን በውሃ ወይም በሌሎች ፈሳሾች ውስጥ አታጥቡት።
• 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.

Familiarize yourself with the components of the Geko G02662 Refractometer:

ምስል 1፡ ጎን view of the Geko G02662 Refractometer. This image displays the overall structure of the device, including the eyepiece, main body, and prism assembly.

ምስል 2፡ Close-up of the prism and cover plate. The sample is applied to the main prism, which is then covered by the transparent plate.

ምስል 3፡ View of the eyepiece. The user looks through this end to read the measurement scale.

1. የአይን ቁራጭ፡ ተጠቅሟል view the measurement scale. Rotate to adjust focus.
2. የላስቲክ መያዣ; Provides a secure hold.
3. ዋና አካል፡- Contains the optical system.
4. የመለኪያ ዊንጣ፡ Used to adjust the zero point (under a cap).
5. ፕሪዝም፡ The surface where the sample is placed.
6. የሽፋን ሳህን; Covers the sampበፕሪዝም ላይ።

5. ማዋቀር

Before first use, or if the focus appears blurry:

1. Hold the refractometer towards a light source.
2. በዐይን ሽፋኑ ውስጥ ይመልከቱ።
3. Rotate the eyepiece (part 1 in Figure 1) until the scale is clear and in sharp focus.

6. የአሠራር መመሪያዎች

Follow these steps to take an accurate measurement:

1. ፕሪዝምን ማጽዳት፡ Ensure the prism (part 5) and cover plate (part 6) are clean and dry using the provided cleaning cloth.
2. ኤስን ተግብርampላይ: Open the cover plate. Using the pipette, place 2-3 drops of the liquid to be tested onto the main prism.
3. Close Cover Plate: Gently close the cover plate so that the liquid spreads evenly across the entire surface of the prism without air bubbles.
4. Wait for Temperature Equalization: Allow approximately 30 seconds for the sample to equalize to the instrument's temperature. This is crucial for accurate readings.
5. መለኪያ አንብብ፡- 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.
6. ከተጠቀሙ በኋላ ማጽዳት; 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. መለካት

Calibration should be performed before first use, after cleaning, or if you suspect inaccurate readings. Use distilled water for calibration.

1. Ensure the refractometer is at room temperature (20°C / 68°F).
2. Clean the prism and cover plate thoroughly.
3. Place 2-3 drops of የተጣራ ውሃ onto the prism. Close the cover plate.
4. Wait 30 seconds for temperature equalization.
5. Look through the eyepiece. The boundary line should align with the 'WATERLINE' or '0' mark on the scale.
6. 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.
7. Clean and dry the prism and cover plate.

8. ጥገና እና እንክብካቤ

• ማጽዳት፡ 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.
• ማከማቻ፡ 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.
• ጉዳትን ያስወግዱ; Do not touch the prism surface with your fingers or any hard objects.
