This digital protractor / clinometer is a useful angle measurement tool for Solar PV installers when setting the angle of inclination for a solar panel.

This upper surface also allows of notes and calculations being made, positions transferred from one chart to another by tracing and so,on.Necessary cookies are absolutely essential for the website to function properly. To plot lines of position and other such problems This can easily be done as the upper surface of the protractor readily allows of lines being ruled and rubbed out. Then reverse the protractor so that the pencil lines are in contact with the objects charted and prick through position as usual. This can easily be done without calculation by using the italic figures if necessary. To fix positions by angles - Lay off the angles observed on the matt side in the opposite direction to that in which they are observed. By using the protractor in the same way the True Course or bearing can be found from the magnetic, or given both true and magnetic the Compass Error may be determined. 340° and then given the Compass Error as 5° W treat the protractor as a movable compass card and move it 5° to the West. To find Magnetic Course or Bearing from true - Set the protractor to the course or bearing, e.g. The same applies to laying or reading off a position for Lat. Another perpendicular will cut off on the 0° - 180° line the number of divisions equaling the difference of latitude. between two positions - Align the protractor to the nearest meridian and a perpendicular from the course line (at the distance given) will cut off on the 90° - 270° line the numbers of divisions equally the departure. Step 1 Calculate gambrel angles with graph paper and a protractor. By this means a bearing or course can be moved anywhere over the chart with no chance of unknown displacement. Secure the tar paper to the plywood sheets with roofing staples. Align the protractor by one of its parallel lines as necessary on the bearing or on the compass and move protractor to the point required by drawing pencil lines either side, of the protractor as necessary. To use a parallel rule - or to take a bearing to or from a compass on the chart. It is here that the great use of the parallel lines is so noticeable, as any line can be used within the limits of the size of the protractor. Align the protractor to the course or bearing and the angle can be read off at once from the nearest meridian or parallel. The left edge can always be distinguished by the writing "Douglas Combined Protractor and Parallel Rule". Use the left side as a ruling edge and the graduation in italic figures on the meridian or parallel - rule the desired course or bearing. How to use the Douglas Navigational Protractor This 4-in-1 drawing tool can be used as a compass, a ruler in inches, a ruler in centimeters and a protractor.
