10 Measuring with a Total Station
Working with a mechanical total station
In addition to the Trimble SPS series of total stations, the software also supports Nikon® and
Trimble mechanical total stations. Most of the functions work exactly like when using a robotic total
station.
1. Set up the total station over a known point and then level it using the bubble and electronic
level of the instrument.
2. Enter atmospheric and other distance correction values using the instruments' on-board
software.
3. Select the method of the station establishment and proceed as described in this chapter.
Measuring with a mechanical total station
Measuring with a mechanical total station works exactly the same as using a robotic total station.
Walking and Vehicle mode are not available with mechanical total stations.
Staking with a mechanical total station
Guidance to a stakeout point works similar to staking with a robotic total station. An additional
arrow on the top right of the Measurement screen indicates how many degrees you need to
manually turn the total station until reaching the direction of the stakeout point.
After the person on the rod was brought in line with the total station, the total station button on
the bottom right will take a measurement. The distance to the point which should be staked is
indicated in the Info bars. Make sure you have GO, horizontal, and vertical angle turned on in the
info bar.
Once the rod is within the stakeout tolerance, tap the button with the stakeout flag to stake the
point and receive the stakeout report. The software creates a Stake Marker report. A graphical
diagram shows how to put an elevation mark on the stake. The way the software calculates the
elevation mark and cut/fill depends on the Stakeout Settings in the Trimble icon menu.
