5. Udhëzimet e funksionimit
5.1. Ndezja/Fikur
Shtypni ON/FIKUR button to power on the device. Press and hold the ON/FIKUR button for approximately 3 seconds to power off.
5.2. Kalibrimi
Regular calibration is crucial for accurate measurements. Refer to the specific calibration procedure for pH and Redox measurements outlined below.
5.2.1. Kalibrimi i pH
- 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.
- Përsëriteni për tretësirat tampon pasuese.
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. Marrja e matjeve
- 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. Mirëmbajtja
