Operation
Entering Values
a prompt for the next digit or decimal entry, and the display will show an
asterisk (
*
) indicating that numeric entry is active . An example of a
numeric entry in progress (numeric entry active) is illustrated below:
Once the numeric value has been entered, press the
ENTER
key to accept
the numeric value. Values are not applied to the operation of the Model
430 Programmer until the
ENTER
key is pressed and the asterisk
disappears from the display. Attempts to set a parameter to a value
outside of the valid range are ignored, and if attempted the Model 430
Programmer will beep once indicating an error and revert to the previous
setting.
If the
ESC
key is pressed while numeric entry is active and digits have
been entered, the entered digits will be cleared and the cursor will remain
for reentry of a new desired value. If the
ESC
key is pressed with no
entered digits on the display, the setting will revert to the previous value
and numeric entry will be made inactive. Thus, if digits have been entered,
the first time ESC is pressed, the entered digits are cleared, but numeric
entry remains active; if
ESC
is then pressed again (with no entered digits
displayed), the setting reverts to its previous value and numeric entry is
made inactive. Note that if the
ESC
key is pressed when numeric entry is
not active, the current submenu will be exited and the next higher level
submenu will be entered.
