2. Setup u Assemblea

Proper setup ensures accurate measurements and extends the life of your instrument. Follow these steps for initial assembly:

Spakkjar: Carefully remove all components from the packaging. Verify that all items listed in the packing list are present: the pH/CON 700 meter, pH electrode, conductivity/temperature probe, electrode stand, and power adapter.
Positioning the Meter: Place the meter on a stable, level surface away from direct sunlight, heat sources, and strong electromagnetic fields.
Assembling the Electrode Stand:
- Attach the base of the stand to the main support rod.
- Secure the electrode holder arm to the support rod at a suitable height.
- Ensure the stand is stable and can securely hold the electrodes.
Connecting Electrodes and Probes:
- Connect the pH electrode to the designated BNC connector on the back of the meter.
- Connect the conductivity/temperature probe to its respective port.
- Carefully place the electrodes into the electrode holder on the stand.
Konnessjoni tal-Enerġija: Connect the provided 110/220 VAC power adapter to the meter's power input and then to a suitable power outlet.
Qawwa Inizjali Mixgħula: Agħfas il-buttuna tal-enerġija (⑂) to turn on the meter. The display should illuminate.

3. Istruzzjonijiet Operattivi

This section outlines the basic operation for pH and conductivity measurements.

3.1. Kejl tal-pH

Preparazzjoni: Rinse the pH electrode with distilled water and gently blot dry with a lint-free tissue.
Kalibrazzjoni:
- Agħfas il- MODALITÀ buttuna biex tagħżel il-mod tal-pH.
- Agħfas il- CAL/MEAS buttuna biex tidħol fil-modalità tal-kalibrazzjoni.
- Immerse the pH electrode into the first pH buffer solution (e.g., pH 7.00). Wait for the reading to stabilize.
- Agħfas ENTER/RANGE biex tikkonferma l-punt tal-kalibrazzjoni.
- Rinse the electrode and repeat for subsequent buffer solutions (e.g., pH 4.01 and pH 10.00).
- Once calibration is complete, the meter will return to measurement mode.
SampKejl tal-le:
- Rinse the calibrated pH electrode with distilled water.
- Għaddas l-elettrodu fl-sample solution. Ensure the electrode junction is fully submerged.
- Allow the reading to stabilize. The pH value and temperature will be displayed.
- Agħfas ŻOMM to freeze the current reading on the display. Press again to release.

3.2. Kejl tal-konduttività

Preparazzjoni: Rinse the conductivity/temperature probe with distilled water.
Kalibrazzjoni:
- Agħfas il- MODALITÀ button to select Conductivity mode.
- Agħfas il- CAL/MEAS buttuna biex tidħol fil-modalità tal-kalibrazzjoni.
- Immerse the probe into a standard conductivity solution (e.g., 1413 µS/cm). Wait for the reading to stabilize.
- Agħfas ENTER/RANGE biex tikkonferma l-punt tal-kalibrazzjoni.
- Rinse the probe and repeat for other standard solutions if multi-point calibration is desired.
SampKejl tal-le:
- Rinse the calibrated conductivity probe with distilled water.
- Għaddas is-sonda fis-sample solution. Ensure the probe tip is fully submerged and free of air bubbles.
- Allow the reading to stabilize. The conductivity value and temperature will be displayed.

4. Manutenzjoni

Regular maintenance ensures the longevity and accuracy of your Oakton pH/CON 700 meter.

Tindif tal-Elettrodu:
- After each use, rinse electrodes and probes thoroughly with distilled or deionized water.
- For stubborn deposits, consult the electrode's specific cleaning instructions.
Ħażna ta 'elettrodi:
- Store pH electrodes in a proper storage solution or pH 4 buffer. Never store dry.
- Conductivity probes can typically be stored dry after rinsing.
Tindif tal-Meter: Imsaħ il-barra tal-miter b'reklamaramp cloth. Do not use abrasive cleaners or solvents. Ensure no liquid enters the meter casing.
Frekwenza tal-Kalibrar: Calibrate the meter regularly, ideally before each measurement session or when high accuracy is required. Calibration frequency depends on usage and sample characteristics.

5 Issolvi l-problemi

Irreferi għal din it-taqsima għal kwistjonijiet komuni u s-soluzzjonijiet potenzjali tagħhom.

Problema	Kawża Possibbli	Soluzzjoni
Unstable pH readings	Dirty electrode; air bubbles; electrode not conditioned; expired buffer.	Clean electrode; ensure no air bubbles; recondition electrode; use fresh buffer.
Inaccurate pH readings	Improper calibration; faulty electrode; temperature not compensated.	Recalibrate with fresh buffers; replace electrode; ensure ATC probe is connected and functioning.
No conductivity reading	Probe not connected; damaged probe; air bubbles in probe cell.	Check probe connection; replace probe; tap probe to dislodge bubbles.
