## 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.

## Quadrant Telemeter Official Manual

The Wndsn Quadrant Telemeter manual provides the description and describes the use of the Telemeter, Horary, and Sine Quadrant.

Mastery of Time and Space is an addendum to the Grimoire Quadrantis Telemetrum which covers setup, history, as well as the functions and tutorials regarding the mastery of space. The addendum explains the functions provided to help master time and date, by observing and calculating the movement of the Sun across the ecliptic, and year.

**This third edition of the manual**, once again revised and expanded, will be of interest to those who want to know what these instruments and the ancient features are all about, to those who have just acquired a Quadrant Telemeter looking for a hands-on introduction to the topic, as well as to the experts who want to push the boundaries of what their Telemeter can do.

The novice as well as the seasoned practitioner with practical interest and the teacher looking to demonstrate concepts in tangible ways are equally addressed and will find big picture information as well as detailed explanations. Various additional reference materials have also been included to create a Rosetta stone of trigonometry and a standalone resource for emergency or austere situations.

### Advanced tutorials
