4 Setup
Setup
An instrument setup with good measuring stability will increase the precision in the measurement result
and allow you to utilize the measurement precision of the FOCUS 35 Total Station to its full extent.
Setup Stability
When an instrument is setup it is important to consider the following:
1. Set tripod legs wide apart to increase the stability of the setup. A setup where one leg is placed on,
for example, asphalt and the other two on soil will still be a stable setup provided that the tripod legs
are set wide enough apart. If it is not possible to set the tripod legs wide apart due to obstacles, then
the tripod can be lowered to increase stability.
2. Make sure that all the screws on the tripod and/or tribrach are tightened to avoid any play.
3. Any high quality tripod and tribrach can be used. However, Spectra Geospatial strongly recommends
the use of tripod heads made of steel, aluminum or similar material. Tripod heads of fiberglass or
other composite materials are not recommended.
