3.3. Instrument setting up
Locate the total station on a stable tripod or on a concrete pillar to guarantee its correct use and follow
these guidelines for instrument setting up.
1. Setting up the Tripod and the Instrument
a. Adjust the tripod's three legs to nearly equal lengths that
meet the height requirements for comfortable measurement.
b. Position the tripod over the station point. The three toes are
firmly supported on the ground as equidistantly as possible,
the center of the circle formed by the toes is close to the
station point, and the tripod plate is nearly horizontal.
c. Take out the instrument and make sure that the instrument
and its tribrach are firmly connected. Place the instrument
onto the top plate of the tripod, fix the instrument with one
hand, align the central knob of the tripod with the center hole
of the tribrach with the other hand and tighten it.
d. Gently push the tribrach to make sure it is securely attached
to the tripod plate.
e. Refine the tripod’s three legs adjustment using the tribrach
spherical level as reference.
Note 1. The quality of the tripod setting up can affect the survey result. Remember to locate the
tripod on a stable surface sticking the metal tips in the ground.
Note 2. It is recommended to check the stability of the tripod before each survey.
2. Leveling up the Instrument
Use tribrach leveling screws to level up the instrument, taking the plate level as reference.
Turn the instrument till the plate level is parallel to a line
shaped with screws A and B. Adjust the screws A and B to make
the bubble in the center of the level.
