7. Make markings at the detected pillar locations.
NOTE
• Detection may be instable when the scanner has just been started up.
To stably detect buried objects, wait for a while before you start scan
operation. Confirm scan results after several times of scan.
• Depending on the detection environment or the material of objects behind
gypsum board, the waveforms may be difficult to see. In addition to scan
results, see other information such as architectural drawings.
