All that matters is the axis of the dome. It should be horizontal, and parallel to the axis of the camera lens.

I usually just hold the meter over my head, pointing toward my back, the same direction as the camera from the subject position. If the lighting is uniform this works well. If dense clouds shade the subject, not so well.
