Hilger Watts Theodolite Manual

The stamped on your theodolite (e.g., Microptic No. 1, No. 2, or a specific serial number code).

Rotate back to the original position and verify. Repeat until the bubble remains perfectly centered through a full 360-degree rotation. Step 4: Centering with the Optical Plummet

Often found in olive-drab carrying cases. The manual for the M2 includes sections on:

The manual is written in a clear and concise manner, making it easy to understand for users with a background in surveying or engineering. The text is accompanied by numerous diagrams, illustrations, and photographs, which help to clarify complex concepts and instrument components.

Many models use a direct reading glass circle system, reducing reading errors. Rugged Build Quality: Designed for stability in the field. Precision Optics: Offering sharp, high-contrast images. hilger watts theodolite manual

A step-by-step guide is given in the 1986 training film: "Setting up a theodolite -- Measuring horizontal angles -- Measuring vertical angles -- Packing up".

Hilger & Watts changed designs subtly over decades.

This article provides a comprehensive deep-dive into the history of Hilger Watts, the specific models they produced, how to locate a , and how to use that manual to keep your instrument in perfect working order.

Tangent screws and leveling screws may require specialized, thin, oil-free grease.

Geodetic surveying, triangulation, high-precision industrial alignment, and laboratory metrology.

Typically a three-screw leveling base used to perfectly level the instrument using the circular and plate bubbles.

Hilger & Watts optical theodolites are masterpieces of mid-20th-century precision engineering. Renowned for their robust construction and exceptionally clear optics, these instruments remain highly valued by surveyors, collectors, and instrument restorers worldwide.

Move your eye slightly up and down or side to side behind the eyepiece. If the crosshairs appear to move relative to the target, adjust the main focus slightly until the movement stops. Step 4: Reading the Angles (The Microptic System)

This feature transforms a static PDF or printed manual into a hands-on restoration and maintenance tool, addressing the specific needs of surveyors and collectors dealing with aging equipment.
