2. Connect the BNC connector of the pH electrode to the meter by aligning the pins and twisting clockwise until secure.
3. Remove the protective storage cap from the electrode tip before use. Ensure the electrode tip is always kept moist when not in use, preferably in a storage solution or pH 7 buffer.

5. 操作手順

5.1 電源のオン/オフ

• メーターをオンにするには、 オン/オフ ボタン。
• To turn the meter OFF, press the オン/オフ button again. The meter also features an automatic shut-off function to conserve battery life.

5.2 キャリブレーション

Regular calibration is crucial for accurate pH measurements. The MW101 PRO supports a two-point calibration process using pH 7.01 and pH 4.01 or pH 10.01 buffer solutions.

1. メーターをオンにします。
2. Rinse the electrode thoroughly with distilled or deionized water and gently blot dry.
3. Immerse the electrode tip into the pH 7.01 buffer solution. Stir gently and wait for the reading to stabilize.
4. Using the small screwdriver provided, adjust the pH 7 ディスプレイに「7.01」と表示されるまで、トリマー（前面パネルにあります）を回します。

5. 電極を蒸留水または脱イオン水で再度洗い流します。
6. Immerse the electrode tip into either the pH 4.01 or pH 10.01 buffer solution (depending on your expected measurement range). Stir gently and wait for the reading to stabilize.
7. 調整する pH 4/10 trimmer until the display shows the value of the second buffer solution (e.g., "4.01" or "10.01").
8. Your meter is now calibrated and ready for use.

5.3測定を行う

1. メーターが調整されていることを確認してください。
2. Rinse the electrode with distilled or deionized water before each measurement.
3. 電極の先端をsに浸しますamp適切なソリューションを選択し、感知電球が完全に水没していることを確認します。
4. Gently stir the solution to ensure homogeneity and wait for the reading on the LCD display to stabilize.
5. Record the pH value displayed.
6. After measurement, rinse the electrode thoroughly and place it back into its storage solution or pH 7 buffer.

5.4温度補償

The MW101 PRO features manual temperature compensation. pH readings are temperature-dependent. For accurate results, adjust the temperature compensation dial to match the temperature of your sampルソリューション。

• Measure the temperature of your sample solution using a thermometer.
• 回転する 温度補正 dial on the meter's front panel to the corresponding temperature value (in °C). The dial ranges from 0 to 50 °C.

6. メンテナンス

6.1 電極の手入れと保管

• Always keep the electrode sensing bulb moist. Store it in a dedicated electrode storage solution or pH 7 buffer solution when not in use. Never store the electrode dry or in distilled/deionized water.
• Rinse the electrode with distilled or deionized water before and after each use.
• If the electrode becomes sluggish or readings are unstable, it may need cleaning. Refer to the electrode manufacturer's instructions for cleaning procedures.
• Replace the electrode if it is damaged or if calibration becomes difficult or impossible.
