Operation
4. Align the guide laser (the sensor's right and left edge lines) with your
intended scan position, and apply the scanner to the gypsum board.
5. Move the scanner slowly side to side
on the partition's surface.
6. Scan results are shown on the
display.
• In the case of a wooden pillar behind
a gypsum board, the depth may not
be shown.
7. Make markings at the detected pillar locations. (See page 34.)
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 material used for the pillar behind the gypsum board,
detection marks may appear narrower in width. In addition to scan results,
see other information such as architectural drawings.
