Turn the theodolite until the long plate bubble is parallel to two of the three leveling footscrews.
Coarse locking screws paired with fine-adjustment tangent screws for both the horizontal (azimuth) and vertical (elevation) movements. 3. Step-by-Step Operating Instructions

Websites such as the Virtual Archive of Wild Heerbrugg, the Surveying Museum, and various university civil engineering archives often host scanned PDF copies of Watts Microptic brochures and operating handbooks.
Looking for the Hilger Watts theodolite manual? This classic optical theodolite—used for precise angular measurements in surveying and engineering—has a well-regarded manual that covers setup, leveling, collimation, reading micrometer verniers, maintenance, and care. Key points to highlight in a post: Turn the theodolite until the long plate bubble
The manual is divided into several sections, each covering a specific aspect of the instrument:
. Turn the instrument 90 degrees and repeat until the bubble stays centered in all directions. Measurement reading micrometer verniers
If the theodolite gets wet in the field, dry it thoroughly with a soft cloth before placing it back in its case. Leave the case open in a dry room overnight to ensure all residual moisture evaporates, preventing internal fungus growth on the optics.
A typical Hilger & Watts theodolite consists of a telescope mounted on a base that rotates around both horizontal and vertical axes. The manual for these instruments outlines several critical components: 0;3b8;0;40a;
to align the etched scale lines before taking a final reading in degrees, minutes, and seconds. Maintenance and Care Microptic transit theodolite, 1954
