5.2 Keys And Interface
The AreaRAE Plus/Pro has three keys:
In addition to their labeled functions, [Y/+], [MODE], and [N/-] act as “soft keys” that control different
parameters and make different selections within the instrument’s menus. From menu to menu, each key
controls a different parameter or makes a different selection.
Three panes along the bottom of the display are “mapped” to the keys. These change as menus change,
but at all times the left pane corresponds to the [Y/+] key, the center pane corresponds to the [MODE]
key, and the right pane corresponds to the [N/-] key. Here are examples that show the relationships of the
keys and functions:
In addition to the functions described above, any of the keys can be used to manually activate display
backlighting. Press any key when the backlighting is off to turn it on. A subsequent key press is required
to carry out an actual function corresponding to that key.
5.2.1 Reverse Direction
Sometimes you want to go back to a previous screen rather than advance through an entire set of screens
before “wrapping around” to that screen again.
To reverse direction:
1. Press and hold [N/-] for 3 seconds.
2. When the arrow changes from pointing to the right to pointing to the left, release your finger.
Now when you press [N/-], you step back through the screens.
To change direction again: Press and hold [N/-] for 3 seconds and then release.
Note: Changing direction does not work with all screens. It works primarily in submenus.
