Pornirea inițială
Press the "ON/OFF" button to power on the device.
4. Funcționare
Preluarea măsurătorilor
- Scoateți capacul de protecție de pe sondă.
- Rinse the probe with distilled water and blot dry with a clean tissue.
- Press the "ON/OFF" button to turn on the meter.
- Dip the electrode into the solution to be measured, ensuring the liquid level is below the immersion line.
- Gently stir the solution and wait for the reading to stabilize on the LCD display.
Schimbarea modurilor de măsurare
Press the "MODE/CAL" button to cycle through the different measurement modes: pH, EC, TDS, Salinity, S.G, ORP, and Temperature. The current mode will be displayed on the screen.

Holding Readings and Temperature Unit Switching
Press the "HOLD/TEMP" button briefly to lock the current reading on the display. Press it again to release.
Long-press the "HOLD/TEMP" button to switch between Celsius (°C) and Fahrenheit (°F) temperature units.
Calibrare
The meter offers instant one-touch calibration. Refer to the included calibration powders for specific instructions on preparing calibration solutions.
- Prepare the calibration solution (e.g., pH 6.86, pH 4.00, pH 9.18 for pH calibration).
- Turn on the meter and select the desired measurement mode (e.g., pH).
- Dip the probe into the calibration solution.
- Long-press the "MODE/CAL" button until the calibration mode is activated (usually indicated by a flashing reading or "CAL" on the screen).
- The meter will automatically recognize the standard solution and calibrate itself. Wait for the reading to stabilize and the calibration to complete.
- Rinse the probe with distilled water after calibration.
Nota: Regular calibration is crucial for maintaining measurement accuracy, especially for pH.
5. Întreținere
Îngrijirea sondei
Always keep the probe clean. After each use, rinse the electrode with distilled water.
Store the probe with the protective cap on, ideally with a small amount of KCL storage solution or distilled water to prevent the electrode from drying out.

Înlocuirea bateriei
Replace batteries when the low battery indicator appears on the screen or when the device fails to power on. Follow the battery installation steps in the "Setup" section.
6. Depanare
Lecturi inexacte
- Calibrare: Ensure the meter is regularly calibrated according to the instructions, especially if readings seem inconsistent. Use fresh calibration solutions.
- Probe Cleanliness: A dirty probe can lead to inaccurate readings. Clean the probe thoroughly with distilled water. For stubborn deposits, a mild cleaning solution recommended for pH electrodes may be used, followed by thorough rinsing.
- Compensarea temperaturii: The meter has automatic temperature compensation. Ensure the temperature of the sample is within the operating range.
- Nivel baterie: Low battery can affect performance. Replace batteries if needed.
Dispozitivul nu pornește
- Check battery installation and ensure batteries are correctly oriented.
- Înlocuiți bateriile cu altele noi.
Probleme de afișare
