The Action Keys
As shown in Figure A-5, the action keys are the six blue, white, and
black keys located above the alphanumeric keys. The function of each
key is described as follows:
ON/OFF Key
Use this key to power the HART Communicator. When the
communicator is turned on, it searches for a transmitter on the
4–20 mA loop. If a device is not found, the communicator displays
the message, “No Device Found. Press OK.”
If a HART-compatible device is found, the communicator displays the
Online Menu with device ID and tag.
Directional Keys
Use these keys to move the cursor up, down, left, or right. The right
arrow key also selects menu options, and the left arrow key returns to
the previous menu.
HOT Key
Use this key to quickly access important, user-defined 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 HART Communicator
manual for more information.
Function Keys
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 label may appear above the F1 key. In menus providing
access to the Home Menu, the label may appear above the F3 key.
Simply press the key to activate the function. See your HART
Communicator manual for details on specific Function Key definitions.
