scanner's pan axis. If the bubble is inside the larger black circle, the inclination of the scanner is
within 5° and the background color of the level is green. If the inclination is larger, the background
color of the level turns red and the accuracy of the inclination measurement might then be reduced.
The two linear levels help to understand the direction of inclination: If the bubble in the upper level
is on the left side, the scanner is tilted to the right (if you are standing in front of the display). If the
scanner is tilted towards you, the bubble in the left level is in the upper half.
Compass
The built-in electronic compass measures the orientation of the scanner on the earth‘s surface. This
information is attached to each scan and can be used during scan registration (for more
information, refer to the Trimble TX5 SCENE Software User Guide). If you want the TX5 SCENE
software to automatically use the compass data during scan registration, switch the Use Compass
button to ON, else switch it to OFF. This setting affects the current scanning parameters and has the
same function as the equivalent button in the parameters settings. See Setting the scan
parameters, page 46.
To see the current orientation of the scanner, tap the Update Compass button. For the
measurement, the scanner needs to turn horizontally by 360°. Make sure that the scanner can
move freely and do not sway the scanner during the measurment.
As soon as the scanner has completed the rotation and determined its orientation, a compass is
displayed as it would appear if mounted on top of the scanner. The compass illustrates the current
scanner orientation and the measured orientation value is displayed in degrees. The given
orientation refers to the direction to which the scanner's left side is currently facing (the left side if
you are standing in front of the scanner‘s display).
To get updated orientation data, for example if the scanner has been moved to another position,
tap Update Compass again.
This manual compass measurement only affects the output on this screen and it is not necessary for
the orientation data measured during scanning. During scanning an orientation measurement is
performed automatically.
