The default equipment (EQ) number is the value that is set to display whenever equipment units are generated on a template (for example, on cover sheets using the <Units_EqNumbField_List> variable).
To change the default EQ number, navigate to the project template (Project Menu > Set Up > Project Template). Under the "Project Settings" tab, find the "Default EQ Number" setting and update the value to the desired output.
Note: The value that it initially selected comes from the project template settings (see article: Project Templates)
If a specific code requires a different EQ value to be generated, the value can be modified for the individual doc code. To make the adjustment, navigate to Project Menu > Cards > Code List and from the "Eq#" column, select a different value directly in the grid for the appropriate doc code.
