4. الإعداد

4.1. تركيب البطارية

The pH meter comes with two 1.5V button cells pre-installed. If replacement is needed:

1. Slide off the battery compartment cover located at the top of the meter.
2. Remove the old batteries and insert two new 1.5V LR44 button cells, ensuring correct polarity.
3. قم باستبدال غطاء حجرة البطارية.

4.2. التحضير الأولي

Before first use or after prolonged storage:

1. قم بإزالة الغطاء الواقي من القطب.
2. اشطف القطب بالماء المقطر.
3. Gently blot dry with a clean tissue. Do not rub.
4. It is recommended to calibrate the meter before initial use.

5. المعايرة

Calibration ensures accurate readings. The VIVOSUN pH meter supports one-point, two-point, or three-point calibration. It is recommended to calibrate the pH meter before each use, especially if it hasn't been used for a while or has been exposed to moisture for an extended period.

5.1. Preparing Buffer Solutions

The meter comes with three pH buffer powders (pH 4.00, pH 6.86, pH 9.18). To prepare the solutions:

1. Empty one packet of buffer powder into a clean 250ml beaker or container.
2. Add 250ml of distilled water to the beaker.
3. قلّب حتى يذوب المسحوق تماماً.
4. Repeat for each buffer powder.

5.2. Calibration Procedure (Three-Point Recommended)

1. Turn on the pH meter by pressing the "ON/OFF" button.
2. Immerse the electrode into the pH 6.86 buffer solution (at 25°C).
3. Press and hold the "CAL" button for 5 seconds. The display will flash "6.86" three times, indicating successful calibration at this point.
4. اشطف القطب الكهربائي بالماء المقطر وجففه برفق.
5. Immerse the electrode into the pH 4.00 buffer solution (at 25°C).
6. Press and hold the "CAL" button for 5 seconds. The display will flash "4.00" three times.
7. اشطف القطب الكهربائي بالماء المقطر وجففه برفق.
8. (Optional for three-point calibration) Immerse the electrode into the pH 9.18 buffer solution (at 25°C).
9. (Optional) Press and hold the "CAL" button for 5 seconds. The display will flash "9.18" three times.
10. After calibration, the meter will automatically save the calibration data and return to measurement mode.

ملحوظة: If the meter cannot identify the buffer solution, it will display "----" and exit calibration mode. Ensure buffer solutions are correctly prepared and the electrode is clean.

6. تعليمات التشغيل

6.1. Measuring pH

1. قم بإزالة الغطاء الواقي.
2. اشطف القطب الكهربائي بالماء المقطر وجففه برفق.
3. Turn on the meter by pressing the "ON/OFF" button.
4. Immerse the electrode into the solution to be tested. Ensure the electrode is fully submerged.
5. Gently stir the solution and wait for the reading to stabilize. The display will show the pH value.
6. The meter features Automatic Temperature Compensation (ATC), which adjusts the pH reading based on the solution's temperature, ensuring accuracy across varying temperatures.

6.2. بعد القياس

1. اشطف القطب بالماء المقطر.
2. Gently blot dry with a clean tissue.
3. استبدل الغطاء الواقي.
4. Turn off the meter by pressing the "ON/OFF" button.

7. الصيانة

7.1. تنظيف القطب الكهربائي

Regular cleaning of the electrode is crucial for accurate readings and extending the meter's lifespan.

• After each use, rinse the electrode thoroughly with distilled water.
• If the electrode is heavily contaminated, soak it in a mild cleaning solution (e.g., pH electrode cleaning solution or a dilute acid solution like vinegar) for 10-20 minutes, then rinse with distilled water.
• Never touch the electrode with your fingers or abrasive materials.

7.2. التخزين

• Always replace the protective cap after use to keep the electrode moist. If the electrode dries out, soak it in pH 4.00 buffer solution or electrode storage solution for at least 30 minutes before use.
• قم بتخزين العداد في مكان بارد وجاف، بعيدًا عن أشعة الشمس المباشرة ودرجات الحرارة القصوى.

8. استكشاف الأخطاء وإصلاحها

• قراءات غير دقيقة:
  • Ensure the meter is properly calibrated. Recalibrate if necessary.
  • Clean the electrode thoroughly.
  • تحقق من مستوى شحن البطارية واستبدلها إذا كان منخفضًا.
  • Ensure the electrode is fully submerged in the solution.
• استجابة بطيئة:
  • The electrode might be dry. Soak it in pH 4.00 buffer solution or electrode storage solution for 30 minutes.
  • The electrode might be dirty. Clean it as per maintenance instructions.
• Display Shows "----":
  • During calibration, this indicates the meter could not recognize the buffer solution. Recheck buffer preparation and ensure the correct solution is used for the calibration point.
  • Outside calibration, this might indicate a sensor error or extremely out-of-range measurement.
• العداد لا يعمل:
  • التحقق من تركيب البطارية والقطبية.
  • استبدال البطاريات بأخرى جديدة.
