CALIBRATION AND SCANNING

OPERATING NOTES
Depending on the proximity of electrical wiring or pipes to the wall surface, the StudTech 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 plumbing, electrical, etc., remember that studs or joists are normally spaced 16 in. (406mm) or 24 in. (610mm) apart and are 1-1/2 in. (38mm) in width. Anything closer together or a different width may not be a stud, joist or firebreak. Always turn off the power when working near electrical wires.
When red LED is lit, the beep sounds, locating the edge of the stud. Mark this spot. Continue scanning beyond the marked spot until the top red LED goes out. Slide unit in reverse direction to locate other edge of stud. Mark this second spot. Middle of stud is centered between the two marks.
WORKING WITH DIFFERENT MATERIALS
The StudTech is designed for use on dry interior walls only. Three primary factors can affect sensing depth: Thickness, density and moisture content. The StudTech is not designed to handle materials with inconsistent density such as: Ceramic floor tile Carpeting and padding Wallpaper with metallic fibers Freshly painted walls that are still damp (must dry at Least a week) Lath and plaster
