Appendix B: Read the Latitude Scale APPENDIX B: How to Read the Latitude Scale The Latitude scale has three sets of measurements, one for each latitude range: 0 to 30°, 30° to 60° and 60 to 90°. Note that there are five extra degrees beyond both 0 and 90°. This allows you to add for latitudes just slightly below 0 and just slightly above 90 degrees. For instructions as to how to set up the wedge for your latitude range, see page 8, latitude adjustment. A short tick marks on the scale represents one-half degree, a long tick marks represents one degree. Line up your latitude with the indicator line at the edge of scale. Count the longer tick marks down to the indicator Line up your latitude with the indicator In the example above, lets say you have chosen the latitude range of 30 to 60 degrees. This is the middle set of numbers (30, 40, 50 and 60). Count the number of longer tick marks from 40 down to the indicator. Always count from the set of numbers closest to the indicator. As there are four longer ticks down to the indicator, the scale reads 44 degrees. If you had chosen the 0 to 30 degree range, the scale reads 14 degrees. Additionally, if you chosen the 60 to 90 degree range, the scale reads 74 degrees. 23
