Scanning parameters like resolution, quality or the scanning angles are the parameters used by the scanner for recording the scan data. There are two ways to set the scanning parameters: Change them manually or select a scan profile which is a predefined set of scanning parameters. When selecting a scan profile, the scanning parameters will be overwritten by the settings of this scan profile.
To choose a predefined scan profile or to change the scanning parameters manually tap the Parameters button on the Home screen.
Selected Profile – Shows the name of the selected scan profile. Tap to select a scan profile. If the scanning parameters differ from the selected profile, altered is appended to its name. Selecting a scan profile overwrites the scanning parameters with the settings of this scan profile.

Horizontal and Vertical Scan Range – Displays the scan range with the horizontal and the vertical start and end angles in degrees. Tap to adjust them.
Select Sensors – Tap to enable or disable the automatic use of data from the built-in sensors for scan registration in TX5 SCENE software.
Note – The available sensors vary depending on the scanner model.
Scan with Color – Switch colored scan recording on or off.
Advanced Settings – Enable or disable the Clear Contour and Clear Sky filters.
Eye Safety Distance – The axial and radial eye safety distance (NOHD). Both values depend on the selected resolution and quality setting. For more information, seeLaser safety, page 16.
Scan Size [Pt] – Shows the size of the scan in points horizontally x vertically. The vertical size may only be changed by setting a new resolution or by changing the scan area angle.
Scan Duration, Scan File Size – Expected scan time and file size in Megabytes according to the chosen resolution, quality value, and scan range. The values shown here are approximate values.
Selecting a scan profile
Prior to capturing a scan, you may select a scan profile that fits the needs of the scene and the desired scan quality.
This view shows a list of all available scan profiles. This list contains factory predefined profiles which are read-only and custom profiles which can be created and manipulated under Manage Profiles.
For more information, seeCreating a scan profile, page 71.
Tap a profile to select it. The selected profile is highlighted. To view the details of the selected profile, tap it again.

Setting resolution and quality
Resolution – The resulting scan resolution. You can choose among 1/1, 1/2, 1/4, 1/5, 1/8, 1/10, 1/16, 1/20 and 1/32. Use the slider on the left to change the resolution of the next scan.
Quality – Affects the quality of the scan and the scanning time at constant scan resolutions. Move the slider up to reduce the noise in the scan data and increases the scan quality. This results in a longer scanning time. Move the slider down to reduce the scanning time and increase the efficiency of your scan project. The Quality slider sets quality levels either via diverse measurement rates or by applying additional noise compression. For more information, seeScanning parameters overview, page 51.
The resulting scan duration, vertical and horizontal scan points (Scan Size [Pt]), as well as the resulting scan size in Mega points (MPts) are displayed in the middle of the view. Point Distance [mm/10m] / [in/30ft] is the distance between the captured scan points in mm (in) in a scan distance of 10 meters (30 ft.).
Depending on the chosen scan resolution only appropriate quality values are selectable (see Scanning parameters overview, page 51).
If you plan to capture several scans from the same position (with different resolutions) and if it is important that these scans have the same horizontal start angle, then you should not switch off the scanner or change the quality between the recordings of these scans.

Setting the scan range
Vertical area – The size of the vertical scan area in degrees. Use the left up and down buttons to change the vertical start angle. Use the right up and down buttons to adjust the vertical end angles.
Horizontal area – The size of the horizontal scan area in degrees. Use the left buttons to change the horizontal start angle. Use the right buttons to adjust the horizontal end angles.
Default Area button – Tap to reset the values to the default scan area (vertical from -60° to 90° and horizontal from 0° to 360°).
The rectangle in this view illustrates the full scan area. If there are scans on the inserted SD card, the preview picture of the last recorded scan is displayed. If there is no preview picture available, a grid is displayed, where the space between the horizontal and vertical lines is equivalent to 30°. The yellow rectangle illustrates the selected scan area.

Selecting the sensors
Use Inclinometer – Enable or disable the automatic use of the inclination measurement of the built-in dual axis compensator (built-inclbuilt-inometer) for scan registration built-in TX5 SCENE software. However, the data of this sensor is always measured and attached to each scan. If the use of the inclinometer data is switched ON, it is automatically used to register the scans in TX5 SCENE software; if it is switched off, the data is ignored. You can change this behavior later in the TX5 SCENE software. For more information, refer to the Trimble TX5 SCENE Software User Guide.
Note – To get the most reliable data from the dual axis compensator, make sure that the scanner‘s inclination is less than 5°. For more information, seeInclinometer (Dual Axis Compensator), page 90.
Use Compass – Enable or disable the automatic use of data from the built-in compass for scan registration in TX5 SCENE software. The data of the compass is always measured and attached to each scan during scanning. If this button is switched to ON the data is automatically used for scan registration. For more information, seeCompass, page 91.
Use Altimeter – Enable or disable the automatic use of altimeter data for scan registration in TX5 SCENE software. The data of the altimeter is always measured and attached to each scan during scanning. If this button is switched to ON the data is automatically used for scan registration. You may want to enter a reference height before starting your scan project. This reference height then acts as basis for all measurements made by the altimeter. Altimeter settings are in Manage / Sensors / Altimeter. For more information, seeAltimeter, page 92.
Click the Recommended Settings button to enable the use of all sensors.

Advanced Settings
Clear Contour – Enables the dynamic contour filter. While scanning, this hardware filter removes incorrect measurements at the edges of objects. It removes scan points resulting from hitting two objects with the laser spot which mainly happens at the edges of objects.
Clear Sky – Enables the dynamic sky filter. While scanning, this hardware filter removes scan points resulting from hitting no objects at all which mainly happens when scanning the sky.
Recommended Settings button – Enables both filters.
