Impostare

1. Installazione della batteria: Open the battery compartment on the back of the meter and insert 4 x 1.5V AAA batteries, ensuring correct polarity. Close the compartment securely.
2. Connessione sonda: Connect the dissolved oxygen probe to the main meter unit using the provided connector. Ensure the connection is firm and secure.
3. Electrolyte Preparation: Carefully open the electrolyte bottle. Using a pipettor, transfer the electrolyte into the probe's membrane cap. Ensure no air bubbles are trapped within the membrane cap.
4. Probe Membrane Installation: Gently screw the probe cover (membrane cap) onto the probe, ensuring the membrane is intact and free from damage.
5. Accensione iniziale: Premere il tasto IMPOSTATO pulsante per accendere il dispositivo.
6. Calibrazione: Refer to the "Calibration" section for initial calibration procedures before first use to ensure accurate readings.

Istruzioni per l'uso

1. Accensione/spegnimento: Premere il tasto IMPOSTATO pulsante per accendere o spegnere il misuratore.
2. Misurazione:
   • Immerse the dissolved oxygen probe into the sample water. Ensure the probe tip is fully submerged and free from air bubbles.
   • Allow a few moments for the reading to stabilize on the digital display.
   • The meter will display dissolved oxygen levels, typically in ppm (parts per million) or mg/L.
3. Cambio unità: Utilizzare il MODALITÀ button to cycle through available measurement units if applicable (e.g., ppm, mg/L).
4. Salvataggio dei dati: After a stable reading, press the SALVA button to record the current data. The meter supports manual recording of up to 99 data points.
5. Richiamo dati: Premere il tasto Richiamo pulsante per view previously saved data. Use arrow buttons (if available) to navigate through records.
6. Compensation Functions: The meter automatically applies temperature, salinity, and altitude compensation. Ensure these parameters are correctly set if manual adjustment options are available.
7. Retroilluminazione: The high-definition backlight screen activates automatically or can be toggled using a specific button (refer to on-screen prompts if available).

Calibrazione

Regular calibration ensures the accuracy of your dissolved oxygen meter. It is recommended to calibrate before first use and periodically thereafter.

1. Preparazione: Ensure the probe is clean and the membrane is properly installed with fresh electrolyte.
2. Accedere alla modalità di calibrazione: Premere e tenere premuto il tasto CAL/ESC button until the meter enters calibration mode. The display will show prompts.
3. Calibrazione dell'aria:
   • Hold the probe in the air (away from strong drafts) and allow the reading to stabilize. This calibrates for 100% air saturation.
   • Premere Enter/TEST to confirm the air calibration.
4. Zero Oxygen Calibration (Optional):
   • If a zero-oxygen solution is available (e.g., prepared with test reagents), immerse the probe into it.
   • Allow the reading to stabilize and press Enter/TEST per confermare.
5. Exit Calibration: Premere CAL/ESC per uscire dalla modalità di calibrazione.

Note: Specific calibration procedures may vary. Always refer to the on-screen prompts during calibration for precise instructions.

Manutenzione

Proper maintenance ensures the longevity and accuracy of your Srliya AR8407 Dissolved Oxygen Meter.

1. Pulizia della sonda:
   • Regularly clean the probe tip and membrane with the provided cloth.
   • If deposits accumulate on metallic parts, gently use the sandpaper to clean them, taking care to avoid damage to the membrane.
   • Rinse the probe with distilled water after each use.
2. Electrolyte Replacement: Replace the electrolyte solution in the probe membrane cap periodically, or if readings become unstable. Follow the electrolyte preparation steps in the "Setup" section.
3. Membrane Inspection/Replacement: Inspect the probe membrane for damage, tears, or contamination. Replace the membrane if necessary, following the instructions for membrane installation.
4. Sostituzione della batteria: When the low battery indicator appears on the display, replace the 4 x 1.5V AAA batteries.
5. Magazzinaggio: Store the meter and probe in the provided storage box in a cool, dry place when not in use. Ensure the probe cap is on to protect the membrane.
