2. Operating tips
For optimum scanning results, it is important to properly hold the ST100 and move slowly when
scanning. The following tips will provide more accurate scanning results:
• Grasp the handle with your thumb on one side and your fingers on the other side. Make sure your
fingertips are resting on the handle and not touching the surface being scanned or the scanning
head of the tool.
• Hold the tool straight up and down, parallel to the studs, and do not rotate the tool. Keep tool flat
against the wall and do not rock, tilt, or press hard when slowly sliding across the surface being
scanned.
• Avoid placing your other hand, or any other part of your body, on the surface being scanned. This
will interfere with the tool’s performance.
• If you’re receiving erratic scanning results, it may be a result of humidity, moisture within the wall
cavity or drywall, or recently applied paint or wallpaper that hasn’t fully dried. While the moisture
may not always be visible, it will interfere with the tool’s sensors. Please allow a few days for the
wall to dry out.
• Depending on the proximity of electrical wiring or pipes to the wall surface, the scanner may
detect them in the same manner as studs. Caution should always be used when nailing, cutting, or
drilling in walls, floors, and ceilings that may contain these items.
• To avoid surprises, remember that studs or joists are normally spaced 16 or 24 in. (41 or 61 cm)
apart and are 1-1
⁄
2 in. (38 mm) in width.
• Anything closer together or a different width may not be a stud, joist, or firebreak. Always
turn off power when working near electrical wires.
