6. USB: Connect to PC for configuration and data export.

Tip: Keep signal cables away from power cables to minimize interference.

Operating Modes

Three primary operating modes: Monitoring, Control, and Data Logging.

1. Monitoring Mode: Displays real-time measurements with color-coded status indicators.
2. Control Mode: Activates relay outputs based on alarm conditions (ON/OFF control or PID).
3. Data Logging Mode: Records measurements at configured intervals.
4. Viewing Data: Access historical data via trend graphs or numerical tables.
5. Alarm Acknowledgment: Acknowledge active alarms via touchscreen or remote command.
6. Calibration Mode: Access via secure menu for field calibration using reference standards.

WARNING! Do not enter calibration mode during normal operation. Ensure stable reference conditions.

Data Logging & Export

1. Logging Configuration: Set sampling interval, select channels to log.
2. Memory Management: View used/free memory, clear logged data if needed.
3. Data Export Options:
   • USB flash drive: Insert USB drive, select data to export in CSV format
   • Network export: FTP or email automated reports (requires configuration)
   • Serial export: Stream data via RS-485 to SCADA systems
4. Report Generation: Create custom reports with timestamps, measurements, alarm events.

Care & Maintenance

Regular maintenance ensures optimal performance and longevity.

1. Cleaning: Use soft, dry cloth for display; mild detergent for enclosure if needed.
2. Calibration: Perform annual calibration using certified reference standards.
3. Battery: Internal clock battery (CR2032) typically lasts 5 years; replace when low battery warning appears.
