5. Kalibravimas

Regular calibration is essential for accurate pH measurements. The MP511 features automatic calibration with buffer recognition.

  1. Prepare Buffers: Ensure you have fresh pH buffer solutions (e.g., pH 4.00, 7.00, 10.01) at room temperature.
  2. Skalavimo elektrodas: Rinse the electrode thoroughly with distilled water and gently blot dry with a lint-free tissue.
  3. Įjunkite kalibravimo režimą: With the meter powered on and in pH mode, press the CAL button. The display will indicate calibration mode.
  4. First Buffer Calibration: Immerse the electrode into the first buffer solution (e.g., pH 7.00). The meter will automatically recognize the buffer and stabilize. Press ENTER patvirtinti.
  5. Subsequent Buffer Calibration: Rinse the electrode again. Immerse it into the next buffer solution (e.g., pH 4.00 or pH 10.01). The meter will recognize and stabilize. Press ENTER to confirm. Repeat for additional buffer points as needed.
  6. Išeiti iš kalibravimo: After completing all desired calibration points, the meter will automatically return to measurement mode or prompt to save calibration.

6. Matavimo režimai

The MP511 offers three distinct measurement modes:

  • Stable Measurement Display Mode: Displays the pH reading once it has stabilized. This is the standard mode for most measurements.
  • Timing Measuring Mode: Allows for measurements at set intervals, useful for monitoring changes over time.
  • Nepertraukiamo matavimo režimas: Provides real-time, continuous pH readings, suitable for dynamic processes.

Refer to the detailed instructions in the full manual for specific steps on how to select and configure each measurement mode.

7. Duomenų valdymas

The MP511 incorporates GLP (Good Laboratory Practice) standard data management features:

  • Duomenų saugykla: The meter can store up to 500 sets of measurement data.
  • Laikymo metodai: Data can be stored manually or automatically at user-defined timing intervals.
  • Duomenų išvestis: An RS232 port is provided for connecting the meter to a computer to transfer stored data using the included software.

8. Priežiūra

Proper maintenance ensures the longevity and accuracy of your pH meter.

  • Elektrodų priežiūra:
    • Always keep the electrode bulb immersed in storage solution when not in use. Never store it dry.
    • Rinse the electrode with distilled water before and after each measurement.
    • Clean the electrode regularly according to the electrode's specific cleaning instructions, especially if readings become sluggish or inaccurate.
  • Skaitiklio valymas: The MP511 meter unit meets IP54 waterproof and dustproof standards. Clean the exterior with a damp audinys. Venkite naudoti stiprių cheminių medžiagų ar abrazyvinių medžiagų.
  • Maitinimo šaltinis: The meter is battery-powered (though also uses a DC 9V adapter). Ensure the power adapter is used correctly. If using internal batteries, replace them as needed.
