4. Asennus
4.1. Akun asennus
- Avaa laitteen takaosassa sijaitsevan paristolokeron kansi.
- Aseta ilmoitetut paristot paikoilleen varmistaen oikea napaisuus (+/-).
- Sulje paristolokeron kansi kunnolla.
4.2. Mittapään liitäntä
- Connect the pH electrode to the designated BNC connector on the device. Ensure a firm connection.
- Connect the temperature probe to its dedicated input jack.
- Ensure all connections are clean and dry before use.
5. Käyttöohjeet
5.1. Virta päälle / pois
Paina ON/OFF -painiketta laitteen käynnistämiseksi. Pidä -painiketta painettuna ON/OFF button for approximately 3 seconds to power off.
5.2. Kalibrointi
Regular calibration is crucial for accurate measurements. Refer to the specific calibration procedure for pH and Redox measurements outlined below.
5.2.1. pH-kalibrointi
- Valmista tuoreita pH-puskuriliuoksia (esim. 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.
- Toista seuraaville puskuriliuoksille.
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. Mittausten tekeminen
- Varmista, että laite on kalibroitu.
- 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.
- Anna lukeman vakiintua näytössä.
- Kirjaa mittaustulos muistiin.
- After measurement, rinse the probe(s) thoroughly and store according to maintenance guidelines.
6. Huolto
6.1. Laitteen puhdistaminen
Wipe the device housing with a soft, damp liinalla. Älä käytä hankaavia puhdistusaineita tai liuottimia. Varmista, ettei nestettä pääse laitteen aukkoihin.
6.2. Probe Care and Storage
- pH-elektrodi: 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.
- Redox-elektrodi: Store in a suitable storage solution or distilled water if not used for extended periods.
- Lämpötila-anturi: Clean with distilled water after each use.
- Regularly inspect probes for damage or contamination.
6.3. Pariston vaihto
Vaihda paristot, kun näytössä näkyy heikon pariston ilmaisin. Katso paristojen asennusohjeet kohdasta 4.1.
7. Vianmääritys
| Ongelma | Mahdollinen syy | Ratkaisu |
|---|---|---|
| Ei näyttöä/laite ei käynnisty | Tyhjät tai väärin asennetut paristot | Tarkista paristojen napaisuus; vaihda paristot. |
| Epävakaat lukemat | Dirty or damaged probe; insufficient immersion; air bubbles; incorrect calibration | Clean probe; ensure proper immersion; remove air bubbles; recalibrate. |
| Incorrect pH readings | Expired buffer solutions; dirty/damaged pH electrode; incorrect calibration | Use fresh buffer solutions; clean/replace electrode; recalibrate. |
| Näytöllä näkyy virheilmoitus | Probe fault; internal device error | Check probe connection and condition. If error persists, contact support. |
