Watts Theodolite Manual - Hilger

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.

The Microptic T0 & T1

These were smaller, less precise instruments (often 20-60 arc-second), designed for construction and mining.

8. Specifications (Typical Watts No. 1)

Summary for the Operator: Treat the Hilger & Watts theodolite as a mechanical clock. It is robust but relies on friction and precise glass wedges. The key skill is the Coincidence Reading—aligning those lines perfectly before writing down the number. If your FL and FR angles differ by more than a few seconds on horizontal measurements, re-level the plate bubble.
