Numeric designer control is the one that gets displayed on implementer interface when an Obs Control is associated to a concept with datatype 'numeric'. Example of concept which has datatype numeric is 'pulse'.
On the left pane, you will be able to see properties relevant to Numeric control (and Obs Control) and can select or unselect them.
More information about properties can be found in Configuring Properties.
Numeric Runtime Control
In runtime mode, Numeric Control is rendered with all the properties that were saved during design time. The properties can't be edited in this mode. Runtime Numeric Control is rendered in the observation forms (templates) on Bahmni. Observations can be captured for the concepts associated to these controls.
