3.3 Modes of Operation

The instrument has three modes of operation: Program, Online, and Maintenance. Each mode has its own menus. Most menu items provide access to sub-level menus. The SET MODE item switches the instrument from one mode to another. Your instrument may have reduced menus if options are not present.

Program mode

Program Mode is an off-line mode for programming (configuring) the instrument. In this mode, all inputs and outputs are frozen. If any of the five relays are assigned as DAT outputs the recorder will stop pulsing them when it is placed into Program Mode. The outputs will remain frozen in their present state, either On or Off.

Online Mode

Online Mode enables full use of the instrument with its inputs, outputs and internal programming. In this mode, it is fully interactive with all externally connected elements.

Maintenance Mode

Maintenance Mode is an off-line mode for maintaining proper and complete functioning of the instrument. Functions include calibration, off-line diagnostic testing, and various setups for operation. In Maintenance Mode, all inputs and outputs are frozen. If any of the five relays are assigned as DAT outputs the recorder will stop pulsing them when it is placed into Maintenance Mode. The outputs will remain frozen in their present state, either On or Off.
