The unit is set in a stand facing south to enable the maximum amount of sun to be recorded edit

Is the author unaware that a southern terrestrial hemisphere exists? — Preceding unsigned comment added by 2.101.29.223 (talk) 12:00, 24 February 2015 (UTC)Reply

Why...? edit

Why is it "read in 10th of an hour"? That seems to be a convention only, as the recording itself is continouus. A clarification seems necessary, because when you word it like in the image caption: "The amount of sunshine is recorded in tenths of an hour" it becomes clearly wrong. To do that one would have to cover the recorder from the sun and only expose it, 10 times an hour, for periods of less than six minutes. -- Theoprakt (talk) 08:18, 1 March 2010 (UTC)Reply
