SCANNING IN METAL OR AC MODE
Select mode. After calibrating (see
2
), continue to hold the power
button and slowly slide the unit across the surface. Mark the spot where the display bars peak and a steady tone
sounds. The SpotLite will also shine a beam of light. Continue in the same direction until display bars reduce.
Reverse direction and mark the spot where the display bars peak from that direction. The midpoint of the two marks is
the approximate center of the object.
In Metal Scan mode, if you calibrate directly over metal, you probably will not detect any metal. Move the unit a few
inches right or left, release the power button, and start over.
In AC Scan mode, if you calibrate over AC voltage, the unit will automatically
recalibrate when you move it.
AC WireWarning
™
For your safety AC WireWarning
™
works continuously in all modes. When AC voltage is detected, the AC Alert warning
icon will be displayed on screen.
Caution: Wires deeper than 2 in. (51 mm), in conduit, or behind plywood shearwall may not be detected. Use extreme
caution under these circumstances or whenever hot AC wires are present. Always turn off power when working near
electrical wires.
SCANNING IN STUD SCAN OR DEEPSCAN
®
MODE
After calibrating (see
2
), continue to hold the power button and slowly slide the unit across the surface. As you
approach the edge of a stud, bars on the display will indicate you are getting close. Continue moving the
scanner slowly until the display indicates the EDGE of the stud.
Continue moving the scanner slowly. The audio signal, SpotLite, and display will indicate the CENTER of the stud (see illus-
trations at the top of next column). Continue in the same direction to find the other edge.
Note: DeepScan
®
may report other things besides studs.

and Helpful Hints.
Depending on the proximity of electrical wiring or pipes to the wall surface, the MultiScanner OneStep may detect
them in the same manner as studs, especially in DeepScan mode. Caution should always be used when nailing,
sawing, or drilling into walls, floors, and ceilings that may contain these items. Because of its increased sensitivity,
DeepScan mode may also detect other things in walls that are not studs.
To avoid surprises, remember that studs or joists are normally spaced 16 in. (406 mm) or 24 in. (610 mm) 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 the power when working near electrical wires.
Working With Different Materials
•
Wallpaper:
The MultiScanner OneStep 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 MultiScanner OneStep to locate studs in Stud
Scan mode. Change to Metal mode to locate nail heads holding laths to studs. If plaster has metal mesh reinforcement,
MultiScanner OneStep 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 mode. Calibrate with cardboard in place.
•
Wood flooring, subflooring, or gypsum drywall over plywood sheathing:
use DeepScan mode.
• MultiScanner OneStep cannot scan for wood studs and joists through ceramic floor tile 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 posi-
tioned.

scanner uses four different scanning modes to detect studs, metal, and hot unshielded AC wiring behind walls, floors, and ceilings, as well as detecting rebar in concrete. For safety, in all modes, MultiScanner
OneStep always looks for and warns users of the presence of hot AC. MultiScanner OneStep is the first tool that shows the
center of studs. It features the SpotLite

Pointing System, which automatically displays a beam of light over the center of a
stud and near metal or AC voltage.

MODE SELECTION
• When looking for studs, always start with the scanner in Stud Scan mode, which scans through surfaces up to
3
⁄
4
inch thick.
• DeepScan
®
mode should only be selected if you know the surface is built-up and thicker than normal construc-
tion. You should always scan the area in Stud Scan mode first, to verify that DeepScan is needed. DeepScan is for
depths between
3
⁄
4
inch and 1
1
⁄
2
inches.
• When scanning for metal pipes or rebar, select Metal Scan mode.
• When scanning for electrical wires, select AC Scan mode.

Calibration.
Place unit flat on wall. Press and hold the power button.
Do not move the unit until calibration is complete (1-2 seconds).
When calibration is complete, the unit will stop blinking and display
the operating mode you selected.
•
Operation.
Move the unit slowly, while keeping it flat against the wall. Do not rock or lift it.
•
Restart At New Location.
If you see this message in Stud Scan mode, you probably started over a stud. Move
the unit a few inches right or left, release the power button, and start over.
• If you calibrate over a stud in DeepScan mode, you probably will not detect any studs. Move the unit a few
inches right or left, release the power button, and start over.
• If you receive a Center or Edge indication immediately after calibration without moving the unit, it probably
wasn’t flat against the wall. Release the power button and start over.
