The Process Units window is used to add, edit, and delete process units and process properties (types of process units), and to specify which process unit within each process property is the default.
To access this window select Setup > Edit Process Units from the Project tab.

Initially the window displays all units of all process properties.
Add a new process unit
-
To add a new process unit, first select the Process Property of the new Unit from the dropdown list. The list of process units then changes to display only the process units of the selected process property (select ALL from the dropdown list to display all units).
-
Click Add Item. A new row of fields is added to the bottom of the list. Enter the details of the new unit in these fields.
-
To edit an existing type, select the desired unit row and edit the details as required.
-
To delete an existing unit, select the desired unit row and select Remove Item.
-
Select Yes to confirm deletion and proceed.
-
To set a unit as the default unit for a process property, check its Default checkbox.
If a unit is set as the default, and if the Apply Default Units checkbox of the Process Data grid is checked, when a value of the unit's process property is entered for an instrument in the Process Data grid, this unit is automatically applied to that value and added to it in the grid.
Create a new process property
-
To create a new process property, select the empty space in the dropdown list (beneath ALL in the list), and enter the name of the new process property.
-
Select Add New Process Property. A process property with the entered name is then created.
-
To delete a process property, delete all the units of that property.
-
To save changes and exit the window, select Save.
-
If more than one unit within a process property has been set as the default, an error message is displayed. The save will not take place and the window will remain open. Rectify the problem and select Save again.
-
To exit the window without saving any changes, select Cancel.
