Atago ES-421 Palette-Style Digital Refractometer Instruction Manual

1. හැඳින්වීම

ඒtago ES-421 Palette-Style Digital Refractometer is designed for fast and accurate concentration readings, making it suitable for on-site use. This compact, portable device features a built-in thermistor for Automatic Temperature Compensation (ATC), eliminating the need for manual temperature correction tables. It provides clear error messages for out-of-range concentrations or temperatures, inadequate sample volume, standardization errors, or low battery conditions. Calibration is straightforward, requiring only distilled water and the zero-adjustment button. The water-resistant design enhances its utility in damp field environments. Additionally, the device allows operators to set custom user scales.

5.1. Calibration (Zero Setting)

Calibration should be performed regularly, especially before critical measurements or if accuracy is in doubt.

1. එස් සහතික කරන්නample well is clean and dry.
2. Apply a few drops of distilled water to the sample well, ensuring the prism surface is fully covered.
3. ඔබන්න ZERO button. The display will show '0.00%' or a similar indication of successful calibration.
4. Wipe the distilled water from the sample well using a soft, lint-free cloth.

5.2. මිනුම් ගැනීම

1. එස් සහතික කරන්නample well is clean and dry.
2. Apply a few drops of the sample liquid to the sample well, ensuring the prism surface is fully covered without air bubbles.
3. ඔබන්න START/ON බොත්තම.
4. The measurement reading will be displayed on the LCD screen.
5. Record the reading if necessary.
6. s පිස දමන්නample from the well immediately after measurement to prevent residue buildup.

5.3. Automatic Temperature Compensation (ATC)

ඒtago ES-421 features a built-in thermistor that automatically compensates for temperature variations within its specified range (up to 40°C). This ensures accurate readings without manual temperature correction tables.

5.4. Setting User Scales

The device provides the ability to set user-defined scales. Refer to the detailed instructions in the full product manual (if available) or contact Atago support for specific procedures on utilizing the පරිමාණය button to configure custom measurement units or ranges.

6. නඩත්තු කිරීම

6.1. Cleaning the Sample හොඳයි

After each use, clean the sample well and prism surface thoroughly with a soft, lint-free cloth or tissue. For stubborn residues, a small amount of distilled water or a mild cleaning solution compatible with the prism material can be used, followed by drying.

6.2. ගබඩා කිරීම

Store the refractometer in a clean, dry place away from direct sunlight, extreme temperatures, and corrosive chemicals. If storing for an extended period, remove the 9V battery to prevent leakage.

6.3. බැටරි ප්රතිස්ථාපනය

When the low-battery indicator appears on the display, replace the 9V battery following the instructions in Section 4.1.

7. දෝශ නිරාකරණය

ඒtago ES-421 provides error messages to assist in troubleshooting common issues:

• Concentrations or Temperatures Out of Range: එස්ample's concentration or temperature exceeds the device's operational limits, an error message will appear. Ensure your sample falls within the 0.0 to 10.0% salinity range and the temperature is within the ATC compensation range (up to 40°C).
• Inadequate Sample පරිමාව: If not enough sample is applied to fully cover the prism, an error will occur. Ensure the prism is completely covered with the liquid.
• Standardization Errors: This may occur during calibration if the distilled water is contaminated or the ZERO button is pressed incorrectly. Re-clean the sample well and re-attempt calibration with fresh distilled water.
• අඩු බැටරි: The display will indicate a low battery. Replace the 9V battery as soon as possible to ensure accurate operation.

If problems persist after following these steps, contact Atago customer support.
