4. Подешавање
4.1 Инсталација батерије
- Unscrew the battery compartment cap located at the top of the meter.
- Insert four LR44 alkaline batteries, ensuring correct polarity.
- Securely replace the battery compartment cap.
4.2 Почетна припрема
- Скините заштитни поклопац са електроде.
- Rinse the electrode with distilled water before first use.
5. Упутство за употребу
5.1 Укључивање/искључивање
Press the power button (usually marked with an ① symbol) to turn the meter on or off.
5.2 Промена режима
Press the 'MODE' button to switch between EC (µS/cm) and TDS (ppm) display. The pH and temperature readings are always displayed simultaneously.
5.3 Мерења
- Ensure the meter is clean and calibrated.
- Уроните електроду у водуample, ensuring the sensor is fully submerged but not exceeding the immersion line.
- Gently stir the meter to remove any air bubbles.
- Wait for the readings on the display to stabilize.
- To hold a reading, press the 'HOLD' button (if available on your model, refer to specific button layout).
- Након мерења, исперите електроду дестилованом водом и вратите заштитну капицу.

5.4 Калибрација
Regular calibration ensures the accuracy of your meter. The EC/TDS function is pre-calibrated from the factory. pH calibration is required periodically.
5.4.1 пХ калибрација
- Prepare the pH buffer solutions (pH 4.00, pH 7.00, pH 10.01) by dissolving the provided powder packets in 250ml of distilled water each.
- Укључите мерач и исперите електроду дестилованом водом.
- Immerse the electrode into the pH 6.86 (or 7.00) buffer solution.
- Press and hold the 'pH CAL' button until the display shows 'CAL' and the pH value starts flashing.
- Wait for the reading to stabilize and automatically calibrate. The meter will usually display 'END' or a stable pH value.
- Исперите електроду дестилованом водом.
- Repeat the process for pH 4.00 and pH 9.18 (or 10.01) buffer solutions, calibrating in ascending or descending order as per the specific model's instructions (typically 7.00 first, then 4.00, then 10.01).

6. Одржавање
6.1 Electrode Cleaning
After each use, rinse the electrode thoroughly with distilled water to remove any residue. Do not use tap water or abrasive materials, as this can damage the sensor.
6.2 Складиштење
Always replace the protective cap after use. For prolonged storage, ensure the pH electrode is kept moist. Refer to the specific instructions for your electrode type regarding storage solution if applicable.
6.3 Замена батерије
When the battery indicator on the display shows low power, replace all four LR44 batteries. The meter's memory function ensures that calibration settings are retained after battery replacement.
КСНУМКС. Решавање проблема
- Нетачна очитавања: If readings appear inconsistent or inaccurate, perform a full pH calibration. Ensure the electrode is clean and free from residue.
- Нестабилна очитавања: Ensure the electrode is fully submerged and gently stirred to remove air bubbles. Allow sufficient time for the reading to stabilize.
- Дисплеј не ради: Проверите ниво напуњености батерија и замените их ако је потребно. Уверите се да су батерије уметнуте са исправним поларитетом.
- pH Calibration Issues: Ensure calibration powders are correctly dissolved in distilled water. Calibrate in the recommended sequence (e.g., pH 7.00 first). If issues persist, the electrode may need replacement.
