Parentah Operasi
Kalibrasi
Regular calibration is essential for accurate pH measurements. Calibrate the meter using at least two standard pH buffer solutions (e.g., pH 4.01, 7.00, and 10.00).
- Nyiapkeun Buffer: Ensure buffer solutions are at room temperature.
- Éléktroda Bilas: Rinse the pH electrode and ATC probe with distilled water and gently blot dry.
- Mimitian Calibration: Refer to the meter's on-screen prompts or specific button sequence (usually a "CAL" button) to enter calibration mode.
- Buffer Kahiji: Immerse the electrode and ATC probe into the first buffer solution (e.g., pH 7.00). Wait for the reading to stabilize, then confirm.
- Second Buffer: Rinse the electrode and probe, then immerse them into the second buffer solution (e.g., pH 4.01 or 10.00). Wait for stabilization and confirm.
- Kalibrasi lengkep: The meter will indicate when calibration is complete.
Nyokot Pangukuran
- Éléktroda Bilas: Rinse the calibrated electrode and ATC probe with distilled water.
- Immerse in Sample: Immerse the electrode and ATC probe into the sample solution. Ensure the electrode junction and temperature sensor are fully submerged.
- Ngastabilkeun Maca: Allow sufficient time for the reading to stabilize. The meter will typically display a "READY" indicator when stable.
- Record Reading: Note the pH and temperature values displayed.
- Beresih Saatos Paké: Rinse the electrode and probe thoroughly with distilled water after each measurement.
Pangropéa
- Panyimpenan éléktroda: Always store the pH electrode in its protective cap filled with electrode storage solution or pH 7 buffer. Never store in distilled water.
- beberesih: Clean the electrode regularly to prevent buildup. For general cleaning, soak in a mild detergent solution, then rinse thoroughly. For stubborn deposits, consult the electrode's specific cleaning instructions.
- Meter Cleaning: Wipe the meter's exterior with a damp lawon. Ulah make bahan kimia kasar atawa cleaners abrasive.
- Frékuénsi Calibration: Calibrate the meter daily or before each use for optimal accuracy, especially when measuring samples with significantly different pH values.
Pamérésan masalah
| Masalah | Mungkin Cukang lantaranana | Solusi |
|---|---|---|
| Bacaan teu stabil | Dirty electrode; air bubbles; electrode not fully immersed; expired buffer; damaged electrode. | Clean electrode; gently tap electrode to remove bubbles; ensure full immersion; use fresh buffer; replace electrode. |
| Bacaan teu akurat | Improper calibration; expired buffer; electrode not conditioned; temperature difference. | Recalibrate with fresh buffers; condition electrode; ensure ATC probe is functioning. |
| Méter teu hurung | Power adapter disconnected; faulty power outlet; meter malfunction. | Check power connections; try a different outlet; contact technical support. |
