Installation and Commissioning Steps
Pre-installation Preparation
- Confirm that on-site power, signal cables, and sampling pipelines are in place.
- Check the instrument appearance for damage and whether accessories are complete.
- Read the safety warnings in the manual to ensure compliance with local electrical codes.
Installation Process
- Fix the analyzer on a bracket or wall to ensure it is vertical and stable.
- Connect the sampling tube to the water inlet and the drain pipe to the drain outlet, avoiding bending.
- Connect to 220V power supply and connect the 4-20mA or RS485 signal cable.
- Turn on the power and observe whether the display starts normally.
Commissioning and Calibration
- Enter the menu to set the range, output mode, and calibration cycle.
- Use standard solutions for zero and span calibration.
- Start the automatic cleaning program and confirm the pipeline is unobstructed.
- Record calibration data and save parameters.
Daily Maintenance and Troubleshooting
- Regular reagent replacement: Based on usage frequency, usually replace every 1-3 months.
- Clean the colorimetric cell: Clean at least once a month to prevent dirt from affecting measurement.
- Check pipelines: Check weekly whether the sampling tube and drain tube are blocked or leaking.
- Common faults: If readings are abnormal, first check whether the reagent has expired, whether the colorimetric cell is contaminated, and whether calibration is overdue.
