The calculator relies on VBA macros for its automated calculations. When you open the file, you will likely see a yellow security warning bar at the top of the Excel window. Click the "Enable Content" button to allow the macros to run. If you don't see this bar, you might need to configure your security settings manually: go to File > Options > Trust Center > Trust Center Settings > Macro Settings , and select "Enable all macros" or "Disable all macros with notification." For security, the latter option is generally safer as it allows you to enable macros on a file-by-file basis.
Follow these steps to safely install and set up your DIN 5480 Excel calculator spreadsheet or macro-enabled workbook. Step 1: Enable the Developer Tab
