Step 3: Move it flat against the wall to scan.
Step 4: Mark where the strongest signal appears.
Note:
1. AC Scan will only detect live (hot) unshielded AC wiring.
2. Factors like humidity, temperature, and even the minor electric
readings from your hand, which all have an impact on the readings from
the wall.
SCANNING DIFFERENT SURFACES
Press MODE button switch to the desired mode: Stud mode 1 for finding
wood or metal studs for 1⁄2 in. (12 mm) ; Stud mode 2 for finding wood or
metal studs for 1 in. (25 mm); Stud mode 3 for finding wood or metal
1½
studs for
in. (38 mm); Metal Scan for locating metal; or AC Scan for
locating live AC wiring.Unit will remain off if Power button is not pressed.
Wallpaper: Multifunctional wall scanner TH511 functions normally on
walls covered with wallpaper or fabric, unless the materials are metallic
foil, contain metallic fibers, or are still wet after application. Wallpaper
may need to dry for several weeks after application.
Freshly painted walls: May take one week or longer to dry after
application.
Lath & plaster: Due to irregularities in plaster thickness, it is difficult for
Multifunctional wall scanner TH511 to locate studs in Stud modes.
Change to Metal Scan mode to locate the nail heads holing wood lath to
the studs. If the plaster has metal mesh reinforcement, Multifunctional
wall scanner TH511 may be unable to detect through that material.
Extremely textured walls or acoustic ceilings:
When scanning a ceiling or wall with an uneven surface, place thin
cardboard on the surface to be scanned and scan over the cardboard in
1½
Stud
in. scan mode. If irregular scanning results are received, switch
to Metal Scan mode to locate nails or drywall screws that line up
vertically where a stud or joist is positioned.
Wood flooring, subflooring, or gypsum drywall over plywood
1½
sheathing: Use Stud
in. scan mode and move the tool slowly. The
Signal Strength Indicator may only display limited bars when the tool
locates a stud through thick surfaces.
Multifunctional wall scanner TH511 cannot scan for wood
studs and joists through concrete or carpet and padding.
In problematic situations, try using Metal Scan to locate
nails or screws that may line up vertically where a stud or
joist is positioned.
Note: Sensing depth and accuracy can vary due to moisture,
content of materials, wall texture, and paint.
WARNING
1. Electrical field locators may not detect live AC wires if wires are more
than 2 in. (51 mm) from the scanned surface, in concrete, encased in
conduit, present behind a plywood shear wall or metallic wall covering, or
if moisture is present in the environment or scanned surface.Always turn
off power when working near electrical wires.
2. Do not assume there are no live electrical wires in the wall. do not
take actions that could be dangerous if the wall contains a live electrical
wire. always turn off the electrical power, gas, and water supplies before
penetrating a surface. failure to follow these instructions may result in
electric shock, fire, and/or serious injury or property damage.always turn
off power when working near electrical wires.
3. Do not rely exclusively on the detector to locate items behind the
scanned surface. Use other information sources to help locate items
before penetrating the surface. Such additional sources include
construction plans, visible points of entry of pipes and wiring into walls,
such as in a basement, and in standard 16 and 24 in. (41 and 61 cm)
stud spacing practices.
