Hot Key

Function Keys

Use this key to quickly access important, user-selectable options when connected to a HART-compatible device. Pressing the HOT KEY turns the HART Communicator on and displays the Hot Key Menu. See “Customizing the Hot Key Menu” in the Rosemount 275 HART Communicator manual for more information.

Use the four software-defined function keys, located below the LCD, to perform software functions. On any given menu, the label appearing above a function key indicates the function of that key for the current menu. As you move among menus, different function key labels appear over the four keys. For example, in menus providing access to on-line help, the HELP label may appear above the F1 key. In menus providing access to the ONLINE MENU, the HOME label may appear above the F3 key. Simply press the key to activate the function. See your Rosemount 275 HART Communicator manual for details on specific function key definitions.

Data Entry

FIGURE A-8. Data Entry Key Sequence.

Some menus require data entry. Use the alphanumeric and shift keys to enter all alphanumeric information into the HART Communicator. If you press an alphanumeric key alone from within an edit menu, the bold character in the center of the key appears. These large characters include the numbers zero through nine, the decimal point (.), and the dash symbol (–).

To enter an alphabetic character, first press the shift key that corresponds to the position of the letter you want on the alphanumeric key. Then press the alphanumeric key. For example, to enter the letter “R”, first press the right shift key, then the “6” key (see Figure A-8). Do not press these keys simultaneously, but one after the other.
