Using the Selection Keys
There are six Selection keys—four “arrow” keys, the Enter key, and the
sign (+/–) key. The functions of the arrow keys depend on the Counter’s
operating mode (i.e., sequencing through choices in the Menu, numeric
entry, state change, etc.). This section describes how the Selection keys
function in these different operating modes.
Sequencing Through the Menu
To access the Menu, press the Shift key, and then press the Menu
(Reset/Local) key.
• Press the up- or down-arrow key to go forward to the next menu
function or back to the previous menu function. Pressing either of these
keys repeatedly cycles through the list of menu functions.
• Press the right-arrow key to select a function. When you do this, the
flashing annunciator ( ) changes direction and the current setting
flashes to indicate that you can now use the up- and down-arrow keys
to cycle through the available settings.
• Press the up- or down-arrow key to move through the list of available
settings for a function. Pressing either of these keys repeatedly cycles
through the list of settings.
• Press the Sign (+/–) key to change the sign of numeric values.
• Press the Enter key to accept the currently displayed setting and exit
the Menu.
NOTE In most cases, when you reach the top or bottom of a list of settings, or the
left or right end of a numerical field, the focus rolls over to the opposite
end of the list of settings, or wraps around to the opposite end of the
numeric field. In some situations, however, this does not occur, because if
it did, you could choose an illegal setting. For these settings, you have to
use the opposite button to cycle back through the values or settings.
