- Ensure all connections are clean and dry before use.
5. Upute za rad
5.1. Uključivanje/isključivanje
Pritisnite tipku UKLJUČENO/ISKLJUČENO button to power on the device. Press and hold the UKLJUČENO/ISKLJUČENO button for approximately 3 seconds to power off.
5.2. Kalibracija
Regular calibration is crucial for accurate measurements. Refer to the specific calibration procedure for pH and Redox measurements outlined below.
5.2.1. pH kalibracija
- Prepare fresh pH buffer solutions (e.g., pH 4.00, 7.00, 10.00).
- Rinse the pH electrode thoroughly with distilled water and blot dry.
- Immerse the electrode in the first buffer solution (e.g., pH 7.00).
- Enter calibration mode as per the device's menu.
- Follow on-screen prompts to confirm the buffer value.
- Repeat for subsequent buffer solutions.
5.2.2. Redox Calibration
Redox electrodes typically do not require calibration in the same way as pH electrodes. However, their functionality can be checked using a known Redox test solution.
5.3. Uzimanje mjerenja
- Ensure the device is calibrated.
- Rinse the probe(s) with distilled water and blot dry.
- Immerse the probe(s) into the sample solution. Ensure the sensing part of the probe is fully submerged.
- Allow the reading to stabilize on the display.
- Record the measurement.
- After measurement, rinse the probe(s) thoroughly and store according to maintenance guidelines.
6. Održavanje
6.1. Čišćenje uređaja
Wipe the device housing with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure no liquid enters the device openings.
6.2. Probe Care and Storage
- pH elektroda: Always keep the pH electrode wet. Store it in a suitable storage solution (e.g., 3M KCl solution or pH 4 buffer). Never store in distilled water.
- Redoks elektroda: Store in a suitable storage solution or distilled water if not used for extended periods.
- Temperaturna sonda: Clean with distilled water after each use.
- Regularly inspect probes for damage or contamination.
6.3. Zamjena baterije
Zamijenite baterije kada se na zaslonu pojavi indikator slabe baterije. Upute za umetanje baterija potražite u odjeljku 4.1.
7. Rješavanje problema
| Problem | Mogući uzrok | Otopina |
|---|---|---|
| Nema zaslona/Uređaj se ne uključuje | Istrošene ili nepravilno postavljene baterije | Provjerite polaritet baterija; zamijenite baterije. |
