Adjust the external mirrors to capture ambient light, or switch on the battery-powered illumination kit if working in low light.
For the modern user, the manual is surprisingly accessible. Unlike contemporary digital manuals that focus on software interfaces, this manual focuses on principles of measurement
Do not force the screws. The instrument must be partially stripped down and cleaned with an organic solvent like white spirit, then lubricated with light instrument oil. Optical axis not perpendicular to the horizontal axis
“Always store the theodolite with the vertical clamp slightly loose and the horizontal clamp tight. This prevents differential thermal stress on the axis.” hilger watts theodolite manual
Field accuracy begins with a solid setup. A Hilger & Watts theodolite typically mounts to a heavy-duty timber or fiberglass tripod using a standard
The Hilger & Watts Microptic theodolite is a precision optical-mechanical instrument, featuring a transit telescope and internal glass circles for measuring vertical and horizontal angles. Key operations include precise leveling, using optical plummets for centering, and taking both face-left and face-right measurements to eliminate instrumental errors. You can find a PDF of the manual at wakanokumot.weebly.com . Microptic transit theodolite, 1954
The Hilger Watts theodolite is a precision instrument that requires careful handling and operation to ensure accurate and reliable measurements. By following the guidelines outlined in this article and consulting the Hilger Watts theodolite manual, users can ensure that their instrument is properly calibrated, maintained, and operated to achieve optimal results. Whether you are a surveyor, engineer, or researcher, this comprehensive guide provides the knowledge and expertise you need to get the most out of your Hilger Watts theodolite. Adjust the external mirrors to capture ambient light,
The Hilger & Watts manual remains the gold standard for understanding classic optical theodolites. Whether you are performing a historical survey or restoring a piece of engineering history, this manual provides the technical "soul" of the machine. digital PDF copy or information on a specific model like the Microptic No. 2
By combining Watts' mechanical precision with Hilger's advanced optical capabilities, the company produced the iconic line of theodolites. These instruments replaced bulky, exposed brass vernier scales with enclosed glass circles read through an internal optical microscope system. Production continued successfully for decades before the company was eventually absorbed by Rank Precision Industries in the late 1960s. 2. Key Models and Specifications
One of the most defining characteristics highlighted in any Hilger Watts theodolite manual is the . Instead of reading degrees and minutes off a metal vernier, operators look through a dedicated reading eyepiece positioned near the main telescope. When you look through the reading eyepiece: The instrument must be partially stripped down and
Depending on the model (No. 1 or No. 2), you will see illuminated glass scales.
We can create a step-by-step guide on performing a to check and adjust the instrument's collimation error.
