- Bar graph display shows temperature, deviation, and power and previous history of parameters
- 9 channel temperature profiler with zoom and data analysis features
- Powerful data logging with data log viewer for SPC
- Compatible with popular Windows spreadsheet or data base software
- Event log captures all operator actions and alarm conditions
- Password protection, access only predefined menu items.
- Flexible easy to use setup menu adapts to almost any type of process or equipment
- Hypertext help system includes technical information, installation, operation guide, troubleshooting and spare parts information
- Conveyor speed parameter setup with high and low limits for conveyorized heating applications
- ActiveX interface for remote control and monitoring from network
Menu Items:
