Figure 3-7: Changing Parameter Values for Different Parameter Types
3.9.1. Confirmation Mechanism
Having changed a value, when the or key is released, the display will blink after a
period of 1.5 seconds, indicating that the new parameter value has been accepted. If any
other key is pressed during the 1.5 second period the parameter value is accepted
immediately.
There are exceptions for specific parameters. Examples of these are:-
Output Power adjustment when in Manual mode. The value is written continuously as the
value is changed.
Alarm Acknowledge. If the Alarm Acknowledge is changed from ‘No’ to ‘Acknowledge’ a
confirmation message appears. Press key to confirm the change. If no key is pressed for
10 seconds the value is restored to its previous value.
3.9.2. Invalid key actions
At any time some state transitions may be invalid, due, for example, to contention with digital
inputs or to the current operating state of the instrument.
Examples are:-
1. Digital inputs have priority over the operator buttons.
2. If a parameter value cannot be changed the ! prompt is not shown
3. If the or button is pressed for a read only parameter a number of dashes, ----, is
displayed.
