Wndsn Quadrant Telemeter Tutorials
Making the most out of our graphical telemetry computers.
Like with many complex instruments, there are multiple ways to solve certain problems and to measure the required inputs. Combining the various functions leads to a multitude of advanced uses.
Inch Scale on the Telemeter
Wndsn Telemeters with an inch scale (models 2021 and later) can be used as a coordinate scale for the ubiquitous 7.5° USGS topo maps. On these 1:24k maps, 1 inch equals 2,000 ft.
Standard U.S. maps have a scale of 1:24,000 since 1" = 2,000' and 1:62,500 which is close to 1" = 1 mile. The real inches/mile is 63,360, but 62,500 gets you close, and 62,500 × 16 = 1 million, or ¼ of a ¼ quad.
