This document introduces Leica Geosystems tripod bases, including the use of bases, torsional rigidity, Leica Geosystems bases, professional series and basic series bases, and bases of other brands.
The manual describes the purpose of the base, which is to level the measurement equipment and align ground reference points. Properly bolting the base to the tripod head ensures reliable installation and measurement accuracy.
It also details the two series of Leica bases – Professional and Basic – including their displacement error limits, torsional stiffness characteristics, and recommended applications such as GPS reference stations and high‑precision angle measurements. This manual is written in Chinese.
| Professional series base displacement error | 1 (3cc) |
|---|---|
| Basic series base displacement error | 3" (10cc) |
| Optical collimator accuracy at 1.5 m height | 0.5 mm |
The base is used to level the measurement equipment and align ground reference points, ensuring stable and reliable measurements.
