5. セットアップ
5.1. 取り付け
The converter can be mounted using the integrated mounting points (screws visible in Figure 1). Ensure the mounting location is stable, free from excessive vibration, and within the specified operating temperature range.
5.2. Connecting the pH Electrode
- Ensure the converter is powered off.
- Carefully connect your pH electrode's BNC connector to the BNC input on the right side of the GPHU 014 MP/BNC converter (refer to Figure 1 and 2).
- 接続が確実であることを確認しますが、締めすぎないようにしてください。
5.3. 電源接続
Connect the appropriate power supply to the converter. Refer to the device labeling for specific voltage and current requirements. Ensure the power source is stable and matches the device's specifications.
5.4. 初期キャリブレーション
Before first use, or after prolonged storage, the pH converter and electrode system must be calibrated. Refer to your pH electrode's manual for specific calibration buffer requirements.
- デバイスの電源を入れます。
- Access the calibration menu using the SET button. (Specific steps may vary, consult the device's on-screen prompts or a more detailed technical manual if available).
- Follow the on-screen instructions to perform a 2-point or 3-point calibration using standard pH buffer solutions (e.g., pH 4.01, 7.00, 10.01).
- Rinse the electrode thoroughly with distilled water between buffer solutions.
- Confirm calibration settings.
6.運用
6.1.測定を行う
- Ensure the pH electrode is properly connected and calibrated.
- Immerse the pH electrode into the sample solution, ensuring the sensing bulb and reference junction are fully submerged.
- Allow sufficient time for the reading to stabilize on the digital display. The display will show the current pH value.
- Note any temperature readings if the electrode has an integrated temperature sensor and ATC (Automatic Temperature Compensation) is active.
6.2. メニューナビゲーション
The SET, ▼, and ▲ buttons are used to navigate through the device's menu options. Press SET to enter the menu or confirm a selection. Use ▼ and ▲ to scroll through options or adjust values.
- SET (1): Enter/Exit menu, confirm selection.
- ▼ (2): Scroll down, decrease value.
- ▲ (3): Scroll up, increase value.
Specific menu functions (e.g., setting alarm limits, output configuration) will be detailed in a more advanced technical manual or on-screen prompts.
7. メンテナンス
7.1. Cleaning the Converter
Wipe the exterior of the converter with a soft, damp 布で拭いてください。研磨剤入りの洗剤や溶剤は使用しないでください。液体がデバイス内に入らないようにしてください。
7.2. pH電極のメンテナンス
Proper maintenance of the pH electrode is crucial for accurate readings and extended lifespan. Refer to your specific pH electrode's instruction manual for detailed care instructions. General guidelines include:
- Always keep the electrode's sensing bulb hydrated, typically in a storage solution or pH 7 buffer. Never store dry.
- Rinse the electrode with distilled or deionized water after each measurement.
- Clean the electrode regularly to remove sample residues. Specific cleaning solutions may be required depending on the application.
- Recalibrate the electrode regularly, especially if readings become unstable or inaccurate.
7.3. ストレージ
When not in use for extended periods, store the converter in a clean, dry environment at room temperature. Ensure the pH electrode is properly stored according to its manufacturer's recommendations.
