6.1.2 Non-editable Fields
If the selected menu line is a non-editable field, the current value for the menu
item will be displayed as well as the “<-Back” menu line. Only the “<-Back”
menu line may be used, which will return the user to the previous screen.
6.1.3 Editable Fields
If the selected menu line is an editable field, the current value for the menu item
will be displayed as well as the “<-Back” menu line. Highlighting the menu item
and pressing enter will change the menu line color from green to black, indicating
that the value may be changed.
Numerical Fields
If the menu item is a numerical value, the up and down arrows may be used to
change the value of the menu item. Each press of the up/down arrow keys will
increment/decrement the numerical value by a value of 1. Pressing and holding
the up/down arrow keys will increment/decrement the numerical value by a
value of 1 for the first 10 counts. After 10 counts, the numerical value will start to
increment/decrement by a value of 5 for the next 10 counts, after which the
value will increase by a value of 50. Releasing the key at any time will restart the
count increment at 1. When the appropriate value is reached, press Enter to keep
the value, and the menu line should change from black to green.
Text Fields
If the menu item is a text value, use the keyboard to type the appropriate text into
the field. Text fields only accept alpha-numeric characters and spaces. No other
character should be used. When the appropriate value is entered, press enter to
keep the value, and the menu line should change from black to green.
The backspace may be used to delete unwanted characters in the event a mistake
was made. No other special control keys are available to help edit the text.
Special Fields
If the menu item is a special field, the up and down arrows may be used to scroll
through the available values for the particular field. When the appropriate value is
reached, press enter to keep the value, and the menu line should change from
black to green.
Note: If the arrow is pressed and held, the same rules apply as though it
were a numeric field. Holding the arrow for more than 10 counts, may
result in some unusual behavior but will not cause harm to the
instrument.
