I think from looking on my YouTube channel, you've bought one of my aero books, no? It should all be explained there, but basically you run a hose to each area you're interested in (ie above and below the bonnet) and find the locations with the biggest difference (high under the bonnet and low on top). It's very interesting doing the testing - and don't forget to do it on a windy day too (because the results will be slightly different). Make sure you select a gauge with the right range - should be in the book.
