The Keys

Data Entry Fields

Direct-Entry Fields
4-2
The following keys on the Optica's front panel are used for
programming:
•
ENTER Performs the function shown on a selected control button.
•
TAB Moves cursor to the next field or control button to select it.
•
SHIFT An alternate action key—each press toggles SHIFT-KEY
mode on or off. When SHIFT-KEY mode is on, a green
annunciator is displayed in the lower left corner of the screen.
SHIFT-KEY mode does the following:
•
accesses the alphabetic characters below the keys on the
alphanumeric keyboard.
•
causes the TAB key to move the cursor backwards through the
fields.
•
Ten alphanumeric keys For entering numbers, letters and math
functions.
•
BSP (Backspace) During direct data entry, deletes the character to
the left of the cursor.
•
Four softkeys:
•
during normal operation, control the sensor heating and
cooling, and balance function.
•
during programming, move the cursor on the screen and select
specific characters for each key on the alphanumeric keyboard.
There are two types of data entry fields:
•
direct entry
•
drop-down boxes
Direct-entry fields allow new values to be entered directly from the
alphanumeric keyboard. Use the left and right softkeys to move the
flashing cursor on the screen to the desired character.
•
To enter numeric data, just press the appropriate key.
•
To enter alphanumeric data, first press SHIFT to access the letters
on the keypad, and then press the appropriate key containing the
desired letter. Finally, press the UP or DOWN arrow softkeys to
step through the letters available for that key, both upper and lower
case.
