| Unit: | SDL_meter | | Class: | TMeter | | Declaration: | property ValueSec: double; |
The ValueSec property specifies the value dislayed by the secondary needle. Setting the ValueSec property to a new value automatically moves the index of the secondary needle into the appropriate position. In addition, the over- or underflow indicators are set accordingly (if turned on), and the events OnNormalRange, OnOverFlow, OnUnderFlow are triggered according to the value.
| Hint: |
The secondary needle is invisible by default. Thus you have to set the sub-property Visible of the property NeedleLayoutSec to TRUE in order to make the secondary needle visible. |
