Image Enhancement Processing; System Test - Sensors & Software Conquest Series Manual

Conquest
To only use the Alpha Lines, move to the Slice View button and change Combo to Alpha and
then select the Slice View button to process the grid data and generate Depth Slice images.
To only use the Numeric Lines, move to the Slice View button and change Combo to Num and
then select the Slice View button to process the grid data and generate Depth Slice images.
To use the Concrete Type from a specific line display the line in Grid Scan mode and select the
Concr Type button to determine the Concrete Type for that line. The concrete type value will
appear in the bottom right corner of the Concr Type button. Then, move to the Slice View button
and change Combo to User. Finally, select the Slice View button to process the grid data and
generate Depth Slice images.
Another way is to collect a Line Scan first to find a clean target, ensuring that the target has been
crossed perpendicularly, and determine the Concrete Type. Collect a grid scan in the usual way
and then use the user-defined Concrete Type option to adjust concrete type before generating
the depth slice images.

Image Enhancement Processing

The IEP feature automatically and continuously tests the system for proper calibration during
operation. If the system is ever found to be out of calibration, the user is immediately prompted to
run the System Test and re-calibrate. The IEP option ensures that Conquest always collects the
highest quality data and displays the most accurate images.
The IEP option is found in the Tools menu and is automatically enabled when Conquest is turned
on and is normally left on. In fact, if the IEP is turned off, the user is informed on all Line Scan,
Grid Scan and Depth Slice screens. As well, the next time that Conquest is turned on, the IEP will
be enabled.
There may be situations when the operator is constantly prompted to run the System Test
resulting in the inability to collect data (see System Test). In these cases, the IEP can be
temporarily turned off. If the IEP is disabled, allow the system to warm up for 5 minutes before
starting data collection. Even if data are collected without IEP, it can still be applied in the
ConquestView software after the data are transferred to a PC.

System Test

The System Test, accessed through the Tools menu, is run to ensure that all Conquest functions
are working properly and the system is properly calibrated.
If the IEP option is enabled, as it usually is, the user is prompted to run the System Test if the
system detects that it is out of calibration.
There are several reasons why system requires the System Test:
1. Replacing hardware components like the sensor head or cable,
2. Large changes in the surface materials in the scan area, for example a grid scan
partially collected on a metal plate on the surface.
3. Working in extremely variable temperature conditions.
