3. Setup and Calibration

3.1 Initial Preparation

1. Remove the protective cap from the electrode.
2. Rinse the electrode with distilled or deionized water.
3. Gently blot dry with a clean tissue. Do not rub.

3.2 Calibration Procedure

Calibration is essential for accurate measurements. The meter comes with 4.00pH, 7.00pH, and 10.01pH buffer solutions. Always calibrate with 7.00pH first, then with 4.00pH for acidic samples or 10.01pH for alkaline samples.

1. Turn on the pH meter by pressing the 'ON/OFF' button.
2. Immerse the electrode into the 7.00pH buffer solution.
3. Press the 'CAL' button and hold until the display shows 'CAL' and then '7.00'. The meter will automatically recognize the buffer and calibrate. Wait for the reading to stabilize and 'END' to appear, indicating successful calibration.
4. Rinse the electrode with distilled water and blot dry.
5. For acidic samples, immerse the electrode into the 4.00pH buffer solution. Press 'CAL' and hold until 'CAL' and then '4.00' appear. Wait for stabilization and 'END'.
6. For alkaline samples, immerse the electrode into the 10.01pH buffer solution. Press 'CAL' and hold until 'CAL' and then '10.01' appear. Wait for stabilization and 'END'.
7. Rinse the electrode thoroughly after each calibration step.

4. Operating Instructions

4.1 Taking a Measurement

1. Ensure the meter is calibrated according to Section 3.2.
2. Clean the pH meter electrode with pure water before and after each use.
3. Turn on the pH meter.
4. Carefully insert the spear-shaped electrode into the food sample. For solid or semi-solid foods, ensure the tip is fully immersed and making good contact.
5. Gently stir the electrode to ensure a homogeneous sample reading.
6. Wait for the reading on the digital display to stabilize. The display will show both pH and temperature.
7. Press the 'HOLD/TEMP' button to freeze the reading if needed. Press again to release.
8. To switch between Celsius and Fahrenheit for temperature, press and hold the 'HOLD/TEMP' button.
9. After measurement, rinse the electrode thoroughly with pure water.
10. Turn off the meter and replace the protective cap.

4.2 Mobile APP Connectivity

The GIDIGI pH03A can connect to a mobile application for enhanced functionality:

• Download the official GIDIGI APP from your device's app store.
• Enable Bluetooth on your mobile device and open the APP.
• Follow the in-app instructions to pair your pH meter.
• Once connected, you can view real-time readings, store up to 1,000 data points, add notes to measurements, and share data.
• The APP also allows you to set custom pH ranges, with values exceeding the range displayed in red for easy identification.

5. Maintenance and Storage

5.1 Electrode Cleaning

Regular cleaning of the electrode is crucial for accurate and consistent readings:

1. After each use, rinse the electrode thoroughly with distilled or deionized water to remove any food residue.
2. For stubborn residues, gently wipe the electrode with a soft cloth or cotton swab moistened with a mild cleaning solution (e.g., diluted detergent) and then rinse thoroughly.
3. Never use abrasive materials or strong solvents on the electrode.

5.2 Electrode Storage

Proper storage of the electrode prevents drying out and extends its lifespan:

1. Always replace the protective cap after use.
2. Ensure the sponge inside the protective cap is kept moist with the provided pH electrode protection solution (1mol potassium chloride (KCL) solution).
3. If the sponge dries out, add 2-3 drops of the protection solution to re-moisten it.
4. Store the meter in a cool, dry place, away from direct sunlight and extreme temperatures.
