Proper setup ensures accurate measurements and extends the life of your instrument. Follow these steps for initial assembly:
- Пакеттен чыгаруу: 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.
- Кубат туташуу: Connect the provided 110/220 VAC power adapter to the meter's power input and then to a suitable power outlet.
- Баштапкы күйгүзүү: Кубат баскычын басыңыз (⑂) to turn on the meter. The display should illuminate.

This section outlines the basic operation for pH and conductivity measurements.
3.1. рН өлчөө
- Даярдоо: Rinse the pH electrode with distilled water and gently blot dry with a lint-free tissue.
- Калибрлөө:
- басыңыз РЕЖИМ рН режимин тандоо үчүн баскыч.
- басыңыз CAL/MEAS калибрлөө режимине өтүү үчүн баскыч.
- Immerse the pH electrode into the first pH buffer solution (e.g., pH 7.00). Wait for the reading to stabilize.
- Басыңыз ENTER/RANGE калибрлөө пунктун ырастоо үчүн.
- Rinse the electrode and repeat for subsequent buffer solutions (e.g., pH 4.01 and pH 10.00).
- Калибрлөө аяктагандан кийин, эсептегич өлчөө режимине кайтып келет.
- Sample өлчөө:

4. Техникалык тейлөө
Regular maintenance ensures the longevity and accuracy of your Oakton pH/CON 700 meter.
- Электродду тазалоо:
- After each use, rinse electrodes and probes thoroughly with distilled or deionized water.
- For stubborn deposits, consult the electrode's specific cleaning instructions.
- Электродду сактоо:
- Store pH electrodes in a proper storage solution or pH 4 buffer. Never store dry.
- Conductivity probes can typically be stored dry after rinsing.
- Эсептегичти тазалоо: Эсептегичтин сыртын жарнама менен сүртүңүзamp cloth. Do not use abrasive cleaners or solvents. Ensure no liquid enters the meter casing.
- Калибрлөө жыштыгы: Calibrate the meter regularly, ideally before each measurement session or when high accuracy is required. Calibration frequency depends on usage and sample characteristics.
