4. Setup jeung Calibration

For accurate readings, the pH meter must be calibrated before first use and regularly thereafter. The kit includes 4.00 pH and 7.00 pH calibration solutions.

4.1 Persiapan Awal

1. Cabut tutup pelindung tina éléktroda.
2. Bilas éléktroda nganggo cai sulingan atanapi deionisasi.
3. Gently blot dry with a clean tissue. Do not rub.

4.2 Prosés Calibration

1. Turn on the pH meter.
2. Immerse the electrode into the 7.00 pH calibration solution. Ensure the electrode is fully submerged.
3. Press and hold the CAL button until the display shows 'CAL' or begins flashing. The meter will automatically recognize the solution and calibrate. Wait for the reading to stabilize.
4. Bilas éléktroda ku cai sulingan jeung blot garing.
5. Immerse the electrode into the 4.00 pH calibration solution.
6. Press and hold the CAL button again. The meter will calibrate to the 4.00 pH solution. Wait for the reading to stabilize.
7. Bilas éléktroda ku cai sulingan jeung blot garing.
8. Your meter is now calibrated and ready for use.

Catetan: Regular calibration (e.g., every few weeks or before critical measurements) is crucial for maintaining accuracy, especially with frequent use or after long periods of storage.

5. Operasi

5.1 Nyandak Pangukuran

1. Ensure the meter is calibrated as described in Section 4.
2. Remove the protective cap and rinse the electrode with distilled water.
3. Celupkeun éléktroda kana sample solution you wish to test. Ensure the electrode is fully submerged.
4. Gently stir the meter in the solution to remove any air bubbles.
5. Wait for the reading on the display to stabilize. This typically takes a few seconds. The display will show both pH and temperature.
6. Record your measurement.
7. After use, rinse the electrode thoroughly with distilled water.

Proper maintenance and storage are crucial for extending the lifespan and accuracy of your pH meter.

6.1 Cleaning the Electrode

• Always rinse the electrode with distilled or deionized water before and after each use.
• If the electrode becomes dirty or contaminated, gently clean it with a soft brush or cotton swab and a mild cleaning solution (e.g., diluted detergent or specialized electrode cleaning solution). Rinse thoroughly afterward.
• Avoid touching the glass membrane directly, as oils from your skin can affect its performance.

6.2 Panyimpenan

• The pH electrode should always be stored in a storage solution or 4.00 pH calibration solution. Never store it dry or in distilled water, as this can damage the glass membrane.
• Ensure the protective cap is securely placed over the electrode when not in use to prevent drying out and physical damage.
