1. INSTALLING THE BATTERY
Press battery door release in with your finger or a coin and lift up to remove
door. Connect new 9-volt battery to cable. Place into the compartment
and press into place. Replace battery door and snap shut.
2. OPERATING TIPS
For optimum scanning results, it is important to properly hold the
MultiScanner
™
i
520 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 or above
the running board 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.
WORKING WITH DIFFERENT MATERIALS
Wallpaper:
MultiScanner
™
i
520 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. If it is difficult to locate a stud in
STUD SCAN mode on fresh paint, switch to METAL SCAN
mode to locate nails or drywall screws holding drywall
to studs.
Lath & plaster:
Due to irregularities in plaster
thickness, it is difficult for MultiScanner
™
i
520 to
locate studs in STUD SCAN mode. Change to METAL
SCAN mode to locate the nail heads holding wood
lath to the studs. If the plaster has metal mesh
reinforcement, MultiScanner
™
i
520 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 STUD DEEPSCAN
™
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 sheathing:
Use
DEEPSCAN
™
mode and move the tool slowly. The Signal Strength Indicator may only
display 1 or 2 bars when the tool locates a stud through thick surfaces.
MultiScanner
™
i
520 cannot scan for wood studs and joists through 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.
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 41 and 61 cm stud spacing practices.
3. SELECTING THE MODE
Move selector switch to the desired mode: STUD SCAN for finding wood or metal
studs; DEEPSCAN
™
for scanning walls over 19 mm thick; METAL SCAN for locating
metal; or AC SCAN for locating live AC wiring.
Unit will remain off if Power button is not pressed.
4. FINDING A STUD
Always
scan for studs with the scanner placed flat against the wall. Move the
mode switch to STUD SCAN, place the tool flat against the wall, then press and
hold the Power button. Wait for beep to confirm calibration has completed before
moving scanner.
Slowly slide tool across surface. EDGE display
will illuminate, indicating location of the stud edge.
Continue sliding tool. When the center of a stud
is located, three bars on the Signal Strength Indicator,
the four Middle bars, CENTER display, and SpotLite
™
Pointing System will all illuminate and the buzzer
will sound.
Note: If any bars display on the screen, metal is present. Small targets or targets deep
within the surface may only illuminate some of the bars and not the center line or audio
tone. In this case, use the highest indication to determine the metal position.
8. SCANNING IN AC MODE
As with METAL SCAN Mode, AC SCAN Mode has interactive calibration and works in
the same manner.
1.
(Figure A)
Move mode switch to AC SCAN mode. Press the tool flat against the
wall, then press and hold the Power button. Wait for the beep to confirm calibration
has completed before moving the tool. Once calibration has completed, slowly slide
the scanner across the surface. Mark the location where you get the highest AC
indication (the most Middle bars on the screen). If it is a strong target, the SpotLite
™
Pointing System will also shine a beam of light and a steady beep will sound. Continue
in same direction until display bars reduce. Reverse direction and mark the spot where
the display bars peak from the reversed direction. The midpoint of the two marks is
the location of the center of the live AC wiring. If the unit indicates live electricity over
a large area, you can reduce the sensitivity of the tool to refine the scanning area and
more accurately locate the live AC wiring by following steps 2 and 3 below.
2.
(Figure B)
To further pinpoint the location of the live AC wiring, scan the area
again. Release the Power button and then turn the unit back on, this time starting on
the wall over one of the previous marks. This will reset the tool to a lower sensitivity
and narrow the scan area.
3.
(Figure C)
Scan in both directions as in Step 2. The area indicated should
become smaller so you can more precisely identify the location of live AC wires.
This procedure can be repeated to narrow the field even further.
Note: AC SCAN will only detect live (hot) unshielded AC wiring. Please refer to the
WARNING statement in number 6, WireWarning
™
Detection, for more important details
and warnings about AC detection.

cannot locate a stud, try STUD DEEPSCAN
™
mode. In STUD
DEEPSCAN
™
mode, the Stud icon will continuously flash.
5. CALIBRATING THE TOOL IN
STUD SCAN/STUD DEEPSCAN
™
MODE
MultiScanner
™
i
520 can be calibrated anywhere on the wall. It provisionally monitors
the subsurface environment 10 times per second and automatically recalibrates, when
needed, to successfully find the center of studs in one step.
• Place MultiScanner
™
i
520 against the wall
before
pressing the Power button in
STUD SCAN or STUD DEEPSCAN
™
mode.
• Once powered on, tool will automatically perform all calibrations. The LCD will
display all icons until calibration is complete. Upon completion of calibration, the
SpotLite
®
Pointing System and buzzer will momentarily activate and the tool will
begin continuous measurements. Continue to press Power button down and keep
the tool flat against the wall and begin scanning.
Note: It is important to wait for calibration to complete (1–2 seconds) before moving
the scanner.
ACT
™
(Auto Correcting Technology)
During scanning, the tool will
automatically recalibrate itself when
needed. This recalibration is transparent
and no indication is made. If an arrow
icon illuminates, the tool calibrated near
or over a stud and then moved away.
The arrow indicates the direction of the
missed stud.
6. WIREWARNING
™
DETECTION
Zircon's WireWarning
™
detection feature works continuously in in STUD SCAN,
STUD DEEPSCAN
™
, and METAL SCAN modes. When live AC voltage is detected,
the AC detection warning indicator will appear in the display. If scanning begins over
a live AC wire, the AC indicator will flash continuously. Use extreme caution under
these circumstances or whenever live AC wiring is present.
Electrical field locators may not detect live AC wires if wires
are more than 51 mm from the scanned surface, encased in
conduit, present behind a plywood shear wall or metallic wall covering, or if
moisture is present in the environment or scanned surface.
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.
7. SCANNING IN METAL MODE
Note: When scanning for studs, use STUD SCAN mode (or Stud DEEPSCAN
™
mode on
thicker walls) to quickly locate the center and edges. Use METAL SCAN to determine
if the previous reading in STUD SCAN was a wood stud, metal stud, or pipe. In METAL
SCAN, only metal drywall screws will be found in wood studs, while metal will be
indicated everywhere on a metal stud or pipe.
METAL SCAN has interactive calibration to adjust to its sensitivity to metal, which
can be used to find the precise location of metal objects in walls, floors, and ceilings.
Maximum sensitivity is ideal for quickly finding the approximate location
of metal. However, sensitivity can be reduced by calibrating the tool closer to metal.
With reduced sensitivity, the area where metal is indicated will be smaller. But in
both cases, the metal target is in the center of the area where the tool indicates metal
is present.
1. Move mode switch to METAL SCAN mode. For maximum metal sensitivity, turn the
tool on in the air by pressing and holding the Power button. This will ensure that it
calibrates away from any metal objects.
(The tool can only be calibrated
off the wall in METAL SCAN mode.)
2.
(Figure A)
While holding the Power button, press the tool flat against the
wall and slowly slide the scanner across the surface. Mark the point where you
get the highest metal indication (the most Middle bars on the screen). If it is a
strong target, the SpotLite
™
Pointing System will also shine a beam of light and a
steady beep will sound. Continue in the same direction until display bars reduce.
Reverse direction and mark the spot where the display bars peak from the
reversed direction. The midpoint of the two marks is the location of the center
of the metal object.
If the unit indicates metal over a large area, you can refine the scanning area to
more accurately locate the metal target by following steps 3 and 4 below.
3.
(Figure B)
To further pinpoint the location of the metal target, scan the area again.
Release the Power button and then turn the unit back on, this time starting on the
wall over one of the previous marks. This will reset the tool to a lower sensitivity and
narrow the scan area.
4.
(Figure C)
To continue to reduce sensitivity and further refine the scanning area,
repeat step 3. This procedure can be repeated multiple times to narrow the field
even further.
WARNING
WARNING
MultiScanner

Multifunction Wall Scanner
Detects other objects besides studs
in STUD SCAN mode.
Finds more targets than there
should be.
• Electrical wiring and metal/plastic pipes may be
near or touching back surface of wall.
• Scan the area in METAL SCAN and AC SCAN to determine if metal or hot AC is present.
• Check for other studs equally spaced to either side 31, 41, or 61 cm apart or for the same stud at several places
directly above or below the first scan area.
• A stud reading would measure approximately 38 mm apart from each edge; anything larger or smaller is most
likely not a stud if not near a door or window.
