pengenalan
This manual provides detailed instructions for the safe and effective use of the Atago PR-201a Palette Series Portable Digital Refractometer. This device is designed for accurate measurement of Brix (0.0 to 60.0%) in liquid samples, featuring automatic temperature compensation (ATC) and a user-scale function. Please read this manual thoroughly before operation and retain it for future reference.
Produk Selesaiview
Atago PR-201a is a portable digital refractometer used to measure the refractive index of liquid samples and convert it to concentration in units of percent by weight (Brix). It is suitable for various applications including fruit juice, coffee, food and beverages, chemicals, and industrial liquids. Key features include:
- Brix measurement range: 0.0 to 60.0%
- High accuracy: ±0.1% Brix
- Automatic Temperature Compensation (ATC) for sample temperatures 10 to 40 °C
- User-scale function for custom concentration calculations
- External Light Interference (ELI) technology for reliable outdoor use
- Ingress Protection (IP)-64 rating for dust and liquid resistance

Persediaan
- Pemasangan Bateri: Open the battery compartment cover on the back of the unit. Insert the included 9V battery, ensuring correct polarity. Close the cover securely.
- Kuasa Awal Hidup: Press the "START/OFF" button to turn on the device. The display will illuminate.
- Pertimbangan Alam Sekitar: Ensure the device is used in an ambient temperature range of 10 to 40 °C for optimal performance. Avoid direct sunlight during measurement if possible, although ELI technology helps mitigate interference.
Arahan Operasi
1. Calibration (Zero Setting)
Calibration should be performed regularly, especially before critical measurements or if the ambient temperature changes significantly.
- Ensure the prism surface is clean and dry.
- Apply a few drops of distilled water onto the prism surface, ensuring it covers the entire surface without air bubbles.
- Close the daylight plate gently.
- Press the "ZERO" button. The display will show "0.0%" or "CAL" briefly, then return to "0.0%". This indicates successful calibration.
- Wipe the distilled water from the prism surface with a soft, clean cloth.
2. Mengambil Pengukuran
- After calibration, ensure the prism surface is clean and dry.
- Apply 0.3 to 0.5 mL (approximately 1-2 drops) of the sample liquid onto the prism surface. Ensure the sample covers the entire surface.
- Close the daylight plate gently.
- Press the "START/OFF" button. The measurement will be displayed in approximately 3 seconds.
- Read the % Brix value from the digital display. The temperature of the sample will also be displayed briefly or can be toggled using the "TEMP" function (if available, based on OCR "TEMP-" button).
- After measurement, clean the prism surface thoroughly with a soft, damp kain dan keringkan.
3. User-Scale Function
The user-scale function allows for custom concentration calculations based on a specific coefficient. This is useful for samples where the Brix reading needs to be converted to a different concentration unit using the formula: Concentration = Brix × Coefficient.
- Press the "SCALE" button to access the user-scale setting.
- Follow the on-screen prompts (if any) or refer to the detailed user-scale programming section in the full manual for specific steps to input your desired coefficient.
- Once set, measurements will be displayed according to your custom scale.
Penyelenggaraan
- Cleaning the Prism: Always clean the prism surface immediately after each use. Use a soft, lint-free cloth dampened with water. Avoid abrasive materials or solvents that could damage the prism.
- Membersihkan Badan: Wipe the instrument body with a soft, dry cloth. Do not immerse the unit in water.
- Storan: Store the refractometer in its carrying case in a cool, dry place, away from direct sunlight and extreme temperatures.
- Penggantian Bateri: Gantikan bateri 9V apabila penunjuk bateri rendah muncul pada paparan.
Menyelesaikan masalah
| Masalah | Kemungkinan Punca | Penyelesaian |
|---|---|---|
| Bacaan tidak tepat | Prism not clean; improper calibration; sample not covering prism; air bubbles in sample. | Clean prism thoroughly; recalibrate with distilled water; ensure sufficient sample volume; remove air bubbles. |
| Peranti tidak dihidupkan | Bateri mati; pemasangan bateri yang salah. | Replace 9V battery; check battery polarity. |
| "ERR" or error message on display | Measurement outside range; sensor issue; extreme temperature. | Memastikan sample is within 0.0-60.0% Brix range; allow device to acclimate to ambient temperature; if persistent, contact customer support. |
