I checked by looking at the beam while driving - ie making sure the dip beam was below a level that would dazzle oncoming drivers. It is easy to see because the beam has a very sharp cut off on dip. You can fine tune the level with the dial on the dash board. The number of turns is dependent on how far out it was to start with.
The other way to do it is as they do it in the garage (I have not tried this myself). See this thread and the link provided by NH Dan for UK set up:

DVTA Vehicle Testing - View Test Stages: Stage 2
" Headlamp Alignment Testing Criteria
The most common type of headlamps fitted to vehicles are those known as European type headlamps which are checked for aim on the dip beam.
These headlamps have an asymmetric dipped beam pattern with a distinctive horizontal cut-off on the right, and a 15 degree wedge of light above the horizontal (the 'Kick up') towards the left.
Any of the following points will result in the vehicle being refused a certificate:
- The beam pattern blurred and does not show a distinctive cut-off point.
- The beam 'kick-up' is to the offside, i.e. The headlamp dips to the right.
- The image break point is not between the vertical -2.0% line (blue vertical line) and the vertical 0% line (black vertical line).
- Headlamp centres not more than 850mm above the ground. The beam horizontal cut-off line (pitch) is not between -0.5% and -2% line (red lines).
OR
- Headlamp centres more than 850mm above the ground. The beam horizontal cut-off line (pitch) is not between -1.25% and -2.75% line (green lines). "
