To avoid surprises, remember that studs or joists are normally spaced
16 or 24 in. (406 or 610 mm) apart and are 1½ in. (38 mm) 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.

Working With Different Materials

• Wallpaper: The MultiScanner® 440 functions normally on walls
covered with wallpaper or fabric, unless the materials are metallic foil,
contain metallic fibers, or are still wet after application.

• Lath & plaster: Due to irregularities in plaster thickness, it is difficult for
the tool to locate studs in STUD SCAN mode. Change to METAL SCAN
mode to locate nail heads holding laths to studs. If plaster has metal mesh
reinforcement, tool will be unable to detect anything through that material.

• Textured walls or acoustic ceilings: When scanning a ceiling or
wall with an uneven surface, place thin cardboard on ceiling or wall
and scan over the cardboard using DEEPSCAN
cardboard in place.

• Wood flooring, subflooring, or gypsum drywall over plywood
sheathing: use DEEPSCAN

• Tool cannot scan for wood studs and joists through ceramic floor tile,
concrete, or carpeting and pad.

• In problem situations, try using METAL SCAN to locate nails or drywall
screws that line up vertically where a stud is positioned.

Note: Sensing depth and accuracy can vary due to moisture, content of
materials, wall texture, and paint. Indoor use only.

WARNING

• Scan the same area with METAL SCAN and AC SCAN. If tool indicates
the presence of metal or hot AC, do NOT assume the original stud
indication is a stud.

• Turn tool off, move over a few inches, press Power Button, and
start again.

• On rough surfaces, place thin cardboard on wall, scanning through
it to help slide scanner more smoothly.

• Move tool over a couple of inches and recalibrate.

• Switch to METAL SCAN mode, where combined with WireWarning
detection, pipes and electrical wiring should be detected.

• Check for other studs equally spaced to either side (12, 16, or 24 in.
apart [305, 406, or 610 mm]) or the same stud at several places
directly above or below the first.

• Use CAUTION when nailing, sawing, or drilling into walls, floors,
and ceilings where these items may exist.

• To narrow detection, turn tool off and on again at the edge of
where wire was first detected and scan again.

• Place your free hand flat against wall near tool to drain static.

• Interpret the pair of LCD bars closest to the center as stud edge.

Switch to DEEPS CAN®, where more bars may appear, to locate the stud.

•

• Always calibrate in air for best sensitivity and to avoid calibrating
over any metal.

• Scan in both horizontal and vertical directions. Metal sensitivity is
increased when metal object is parallel to sensor, located at front
end of tool beneath crosshair.

• To reduce sensitivity, recalibrate tool over either of first
two marks.

• Detect outer edges so you know where to begin.

• Try METAL SCAN to see if you can find metal, wire, or metal conduit.

• Always turn off the power when working near electrical wires.

• Try turning on switches to outlet.

• Try plugging a lamp into outlet and turning on switch.
