Hilger Watts Theodolite Manual !!install!! Page

Hilger & Watts produced several theodolite models, each with unique features. Understanding the model is the first step to finding the correct manual, which is often listed by model number (e.g., ST-156) or catalogue number (e.g., CS 16/4).

Located parallel to or alongside the main telescope; displays the internal glass scale readings.

Read the vertical circle through the micrometer eyepiece.

If the difference deviates significantly, use the small adjusting screws near the telescope eyepiece to gently shift the reticle retical plate sideways until half the error is eliminated. Care and Cleaning hilger watts theodolite manual

Always lock the transit clamps lightly when storing the instrument in its fitted metal or wooden case. Carry the case using the provided handles; never drop or subject it to heavy vibrations. 5. Troubleshooting Common Issues

Proper setup is crucial for accuracy. Following the procedures ensures a stable instrument.

The Hilger Watts theodolite is a type of optical theodolite that uses a telescope and a rotating alidade to measure horizontal and vertical angles. Its high degree of accuracy and reliability makes it an essential tool for surveyors, engineers, and researchers. The instrument is designed to withstand harsh environmental conditions and is built with high-quality materials to ensure durability and longevity.

Adjust the focus until the crosshair and the ground mark are both sharp.

Identify the index line. Read the full degrees and tens of minutes passed by the index.

If you need an actual for a specific Hilger Watts model (e.g., Microptic 2″ ), I can point you to archive sources or help interpret a manual you already have. Let me know which model you’re working with. Read the vertical circle through the micrometer eyepiece

Physical copies can be difficult to find and are often prone to "field wear" (stains and torn pages).

Look at the lower micrometer window to read the remaining single minutes and exact seconds. Add the values together (e.g., Main Scale: , Micrometer: 6. Field Adjustments and Maintenance

Slide the theodolite across the flat tripod head until the plummet crosshairs sit exactly over the ground mark. Tighten the tripod centering screw completely. Step 4: Leveling the Instrument
