Installation and Commissioning
Installation Steps
- Select a flat, vibration-free wall or bracket for mounting the transmitter.
- Connect the sampling tube to the analyzer inlet, ensuring no leakage.
- Connect power and signal cables, ensuring reliable grounding.
- Turn on the power and preheat for 30 minutes.
Commissioning Points
- Use standard solutions for zero calibration and span calibration.
- Set appropriate measurement cycle and cleaning interval.
- Check if the peristaltic pump tube is aged and replace if necessary.
Routine Maintenance and Troubleshooting
Regular maintenance ensures long-term stable operation of the CA80AM. Monthly inspections are recommended.
- Reagent Replacement: Regularly replace ammonia nitrogen reagents as required by the manual to avoid expiration.
- Electrode Cleaning: If using the electrode method, wipe the sensitive membrane with a soft cloth to avoid scratches.
- Tubing Cleaning: Clean the sampling tubing quarterly to prevent blockages.
- Common Faults: For reading drift or frequent alarms, first check reagents and electrodes, then contact the manufacturer.
Precautions
- Be sure to read the CA80AM Ammonia Nitrogen Measurement Manual before operation.
- Reagents are corrosive; wear protective gloves and goggles during operation.
- Dispose of waste reagents and waste liquid in accordance with local environmental regulations.
