10 Measuring with a Total Station
Connecting to a total station
When you start the software, it automatically looks for a connection to the total station through a
cable connection. If the instrument is a robotic total station, the connection can also be made
through the internal radio of the controller or an external 2.4 GHz radio. When the connection is
made, the Level Compensator screen (see page 93) appears.
If you leave the controller in GPS mode, it cannot find the connection even if it is connected directly
to a total station. If you are using Bluetooth wireless technology to connect to the total station
(SPS700, SPSx10, SPSx20 or SPSx30), you must first turn on the total station, enable the Bluetooth
connection using the face 2 display menu, and then manually force the connection to it.
If you are using a radio to connect to the total station, you need to manually force the connection
to it.
To force a connection using either a radio or Bluetooth wireless connection:
1. Go to the Trimble icon menu and select Total Station.
2. Select Trimble as a Brand.
3. Select SPS Series as instrument.
4. Select Bluetooth or Radio.
5. Select the Radio channel and Network ID.
6. Follow the instructions that appear on the screen.
Leveling the total station
The compensator inside the total station provides dual-axis correction for any mislevel of the
instrument during operation, for a working range of up to 6' of arc. The display enables you to level
the total station accurately using the foot-screws on the tribrach:
