5. Operasi

5.1 Langkah Pengukuran Asas

1. Tanggalkan penutup pelindung dari elektrod.
2. Rinse the electrode with distilled water and gently blot dry with a clean tissue.
3. Immerse the electrode into the solution to be tested, ensuring the immersion line is covered.
4. Gently stir the solution and wait for the reading to stabilize on the LCD display.
5. The display will show pH, TDS/EC, and Temperature readings simultaneously.
6. Selepas pengukuran, bilas elektrod dengan air suling dan pasang semula penutup pelindung.

5.2 Fungsi Butang

• HIDUP/MATI: Tekan untuk menghidupkan atau mematikan peranti.
• HOLD/TEMP:
  • Short press: Hold the current reading on the display. Press again to release.
  • Long press: Switch between Celsius (°C) and Fahrenheit (°F) for temperature display.
• MODE/CAL:
  • Short press: Cycle through different measurement modes (e.g., pH, TDS, EC).
  • Long press: Enter calibration mode (refer to Section 6 for detailed calibration instructions).

5.3 YINMIK App Features

The YINMIK app provides enhanced control and data management capabilities.

• Paparan Data masa nyata: View all parameters (pH, TDS, EC, Temp) simultaneously on your phone.
• Penyegerakan Data: Measured data is synchronized to the app, allowing for convenient viewing and analysis without frequent operation of the meter itself.
• Data Hold and Save: Use the "Hold Reading" and "Save Reading" functions within the app to capture and store data.
• Cloud-Based Data Management: Easily save, manage, and share test data, preventing data loss.
• Tetapan Boleh Disesuaikan:
  • Kawalan Lampu Latar: Control the backlight of the tester's display via the app.
  • Parameter Limits: Set upper and lower limits for pH and EC. If a measurement exceeds these limits, the value will display in red on the app interface, alerting you to abnormal readings.
  • Auto-Save Interval: Configure the interval for automatic data saving.

6. Penentukuran

Regular calibration ensures the accuracy of your measurements. The BLE-9908 supports a 5-point pH calibration method and comes with calibration powders for both Asia Standard (pH 4.00, 6.86, 9.18) and EU Standard (pH 7.00, 10.01).

6.1 Penentukuran pH

1. Prepare the calibration buffer solutions (e.g., pH 4.00, pH 6.86, pH 9.18 for Asia Standard). Ensure the buffer solutions are at room temperature.
2. Turn on the tester and rinse the electrode with distilled water.
3. Tekan lama MODE/CAL button to enter calibration mode. The display will show "CAL".
4. Immerse the electrode into the first buffer solution (e.g., pH 6.86). The tester will automatically recognize the buffer and begin calibration. Wait for the reading to stabilize and confirm.
5. Bilas elektrod dengan air suling.
6. Immerse the electrode into the second buffer solution (e.g., pH 4.00). The tester will again recognize and calibrate.
7. Bilas elektrod dengan air suling.
8. Immerse the electrode into the third buffer solution (e.g., pH 9.18).
9. Repeat for any additional calibration points as needed. The app can guide you through the 5-point calibration process.
10. Once all desired points are calibrated, the tester will automatically exit calibration mode, or you can short press MODE/CAL untuk keluar.

Nota: Always calibrate with fresh buffer solutions. Discard used buffer solutions after calibration.

6.2 EC/TDS Calibration

EC/TDS calibration typically uses a single point standard solution (e.g., 1413 µS/cm).

1. Prepare the EC standard solution (e.g., 1413 µS/cm).
2. Turn on the tester and rinse the electrode with distilled water.
3. Tekan lama MODE/CAL button to enter calibration mode.
4. Tekan pendek MODE/CAL to cycle to the EC calibration option.
5. Immerse the electrode into the EC standard solution. The tester will automatically recognize the buffer and begin calibration.
6. Wait for the reading to stabilize and confirm the calibration.
7. Rinse the electrode with distilled water and exit calibration mode.

7. Penyelenggaraan

7.1 Electrode Cleaning

• After each use, rinse the electrode thoroughly with distilled or deionized water to remove any residue.
• For stubborn contaminants, soak the electrode in a mild cleaning solution (e.g., electrode cleaning solution or a dilute detergent solution) for 10-15 minutes, then rinse thoroughly.
• Never scrub the glass bulb of the pH electrode, as this can damage it.

7.2 Penyimpanan

• Sentiasa ganti penutup pelindung selepas digunakan.
• For optimal performance and longevity of the pH electrode, keep the electrode moist. Add a few drops of KCL storage solution or pH 4.00 buffer solution to the protective cap before replacing it. Never store in distilled water.
• Simpan peranti di tempat yang sejuk dan kering, jauh dari cahaya matahari langsung dan suhu yang melampau.

7.3 Penggantian Bateri

• When the battery indicator on the display shows low power, replace the batteries promptly.
• Refer to Section 4.1 for battery installation instructions.
