V. Important Considerations

1. Installation & Wiring: Installers should be electricians familiar with national electrical codes and relevant wiring standards. Ensure proper grounding of the transmitter to avoid electrical hazards and measurement errors.

2. Sensor Selection & Maintenance: Select sensors compatible with the measurement medium and temperature range. Regularly clean and calibrate sensors to maintain measurement accuracy. Although the transmitter is compatible with various sensors, ABB sensors are recommended for optimal performance.

3. Environmental Conditions: Ensure the operating ambient temperature is within the specified range (-20°C to 60°C). Avoid installation locations with extreme temperatures, highly corrosive gases, or strong mechanical vibration.

4. Calibration & Configuration: Calibration and configuration should be performed by technicians with knowledge of pH/ORP/pION measurement and electronic instrumentation. Use fresh standard buffer solutions for calibration.

5. Safe Operation: Operators and maintenance personnel should be aware of process risks and follow safety procedures. Always read and understand the product manual before attempting any operation, maintenance, or repair procedure.

6. Lightning Protection: If the model includes a Lightning Suppressor, it helps protect the device from surge damage. However, additional surge protection measures are still recommended in areas prone to thunderstorms.
