##### Freezing and Unfreezing Limits

Freezing and Unfreezing Limits – You can freeze or unfreeze control limits for selected variables.

Clicking the Freeze Limits icon (or selecting the Monitor | Freeze Control Limits menu item) makes it so that the database does not recalculate control limits when new data gets added to the database. Control limits are calculated using the current data and saved to the database.

Clicking the Unfreeze Limits (or selecting the Monitor | Unfreeze Control Limits menu item) icon unfreezes the control limits to their previous state, allowing the system to recalculate control limits, the system will recalculate control limits for the selected variables whenever new data is added to the database.

To view the state of the limits, select View | Variables | Form Editor within the DataPage/RT Editor. See your DataPage/RT Editor documentation for more information.
