• ON/OFF/RESET Button: Long press for 5 seconds to turn on/off or reset pH.
• HOLD/Temp Button: Press to hold the current reading or switch between temperature units.
• CAL hnappur: Long press for 5 seconds to enter calibration mode.
• Rafhlöðuhólf: Houses 3*1.5V LR44 batteries.
• High Sensitive Green Glass Electrode: For accurate and reliable results.
• MAX/MIN Immersion Lines: Indicate the appropriate immersion depth for the electrode.
• Hlífðarhetta: Hylur rafskautið þegar það er ekki í notkun.

5. Uppsetning

5.1 Uppsetning rafhlöðu

1. Locate the battery compartment at the top of the meter (refer to Product Overview mynd).
2. Open the compartment and insert three 1.5V LR44 button cell batteries, ensuring correct polarity.
3. Lokaðu rafhlöðuhólfinu örugglega.

5.2 Upphafsundirbúningur

1. Remove the protective cap from the electrode tip.
2. Rinse the electrode with distilled water and gently blot dry with a clean, soft tissue. Do not rub.

6. Notkunarleiðbeiningar

6.1 Að taka mælingu

Follow these simple steps to obtain an accurate pH reading.

1. Long press the ON/OFF/RESET button for 5 seconds to turn on the meter.
2. Immerse the electrode into the sample solution, ensuring the liquid level is between the MAX and MIN immersion lines.
3. Gently stir the meter to remove any air bubbles around the electrode.
4. Wait for the reading on the display to stabilize (typically a few seconds). The meter will show both pH and temperature.
5. Press the HOLD/Temp button to freeze the current reading on the display. Press again to release.
6. Eftir notkun skal skola rafskautið með eimuðu vatni og setja hlífðarlokið aftur á.
7. Long press the ON/OFF/RESET button for 5 seconds to turn off the meter.

6.2 Skilningur á skjánum

The meter features a color display that shows both the pH value and the temperature. The pH value is presented clearly, often with a color indication that changes according to the value, similar to pH test strips but with precise numerical data.

The GIDIGI pH meter provides clear digital readings with color changes, offering a more precise alternative to traditional pH test strips.

7. Kvörðun

Regular calibration is essential for maintaining the accuracy of your pH meter. It is recommended to calibrate the meter before first use, after prolonged storage, or if you suspect inaccurate readings.

7.1 Calibration Procedure (Two-Point Calibration)

1. Prepare two clean beakers or measuring cups. Pour a small amount of pH 4.00 buffer solution into one and pH 7.00 buffer solution into the other.
2. Turn on the pH meter.
3. Skolið rafskautið með eimuðu vatni og þurrkið varlega.
4. Dýfið rafskautinu ofan í stuðpúðalausnina með pH 7.00.
5. Ýttu lengi á CAL button for 5 seconds until the display shows 'CAL' and then '7.00'. The meter will automatically recognize the buffer and begin calibration.
6. Wait for the reading to stabilize and for the meter to confirm calibration (e.g., 'END' or a stable 7.00 reading).
7. Skolið rafskautið með eimuðu vatni og þurrkið varlega.
8. Now, immerse the electrode into the pH 4.00 buffer solution.
9. Ýttu lengi á CAL button for 5 seconds again. The meter will recognize the buffer and begin calibration for pH 4.00.
10. Wait for the reading to stabilize and for the meter to confirm calibration.
11. After successful calibration, rinse the electrode with distilled water and store it properly.

Athugið: Always calibrate with pH 7.00 first, then with pH 4.00 (or pH 10.00 if needed for alkaline range). Ensure the buffer solutions are at room temperature for accurate calibration.

8. Viðhald

8.1 Þrif á rafskautum

After each use, rinse the electrode thoroughly with distilled water to remove any residue. If the electrode becomes dirty or contaminated, gently clean it with a soft brush and a mild detergent solution, then rinse thoroughly with distilled water.

8.2 Geymsla rafskauta

Proper storage of the electrode is crucial for its lifespan and accuracy. Always keep the electrode moist by storing it in the provided pH Electrode Storage Solution. Never store the electrode dry or in distilled water, as this can damage the glass membrane.

Use the GIDIGI pH Electrode Storage Solution to keep the electrode moist, which helps maintain its lifespan and accuracy.

8.3 Buffer and Storage Solution Care

• Keep buffer and storage solutions in a dry, cool place away from light.
• The bottle mouth is sealed with a thick foam pad and an easy-to-tear gasket for double-layer protection against leakage.
• The solutions are designed to be stable and not easily evaporate after opening.
• Discard used calibration solution after each use; do not pour it back into the original bottle to avoid contamination.
• Unopened solutions are valid for 3 years; once opened, they are valid for 1.5 years.

The upgraded pH solutions are formulated for stability, accuracy, and extended use, with features to prevent evaporation.
