Figure 2Ć13: Numeric input using the numeric keys
This example shows how to change the clock frequency to 12.3 Hz when the
value before entering the input state was 100.0 Hz. When the 1, 2, ., 3, and
ENTER keys are pressed in that order, the numeric input window changes as
shown in Table 2-7.
Table 2Ć7: Numeric input example
Press keys in this order Numeric input window display State of the value
Pressing a units button after a value has been entered confirms both the value
and the unit in a single operation. Pressing a units button before entering the
input state changes only the unit without changing the value.
If you switch to another menu item after entering a value but without pressing
either the ENTER key or a units button, the entered value is discarded and the
value returns to its previous value. If a value outside the allowable range of a
parameter is set, the value will be replaced with the largest or smallest value
allowable for that parameter.
