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.

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.

The official Wndsn Quadrant Telemeter manual. The cover design pays homage to medieval mathematical and astronomical books; the styling of the title as a "Grimoire" is a play on textbooks of magic with instructions on how to make spells, talismans, and the like, "Grimoire Quadrantis Telemetrum" -- Textbook of the magic of Quadrants and Telemeters. Finally; the author's name at the top; "Filiusventi" is a hint at the practice of Renaissance scientists to latinize their names; venti is wind, and filius the son.

The manual provides advanced tutorials on the following topics:

• Measuring the Depth of a Well
• Determining Local Latitude
• Finding Tangent
• Measuring from an Elevation
• Measuring an Elevated Object
• Finding Sine and Cosine
• Extending the Scales
• Powers of 10 and Scale Jumps
• Measuring Size Instead of Distance
• Resection: Triangulation, Trilateration, Triangulateration
• Resection Error Margins
• Small-Angle Calculations

Also, a section on metrology covers:

• Uncertainty
• Accuracy vs. Precision
• Accuracy Estimations
• Calibrating Device Resolution

All new or substantially revised:

• Sun Sighting
• Sun Calculations
• Measuring Local Latitude
• Measuring Sun Altitude
• Using The Obliquity Arc
• Calculating Sun Declination
• Calculating Sun Altitude

• Using the Calendar
• Measuring Time
• Seasonal ("Unequal") Hours
• Equinoctial ("Equal") Hours
• Solar Time

• Great Circle Calculations
• Determining Sunrise Bearing
• The Hour Angle
• Sun Azimuth from Hour Angle
• Sun Azimuth from Sun Altitude
• Latitude from Sun Altitude
