1. INSTALLING THE BATTERY
Push in the battery door tab at the bottom of the
tool and open the door. Insert a new 9V battery,
matching the positive (+) and negative (-)
terminals to the icons printed on the back.
Snap the battery into place and replace the door.
Low Battery Indicator:
The Low Battery Indicator
icon displays when the battery level is getting low.
While the tool will still operate, the battery will need to
be replaced soon. When the battery icon begins to flash
and is the only icon displayed on the screen, the battery
level is too low and not sufficient to power the tool for
proper operation. Please replace the 9V battery with a
brand new battery immediately.
Zircon stud finders and detectors, particularly those with LCD screens,
require and consume a great deal of current from batteries. For optimal
performance, brand-new, recently purchased alkaline batteries are strongly
recommended for use in these tools. If you are experiencing any trouble
with your tool, please replace the battery in your tool with a brand-new
one, contact your Zircon dealer or e-mail at [email protected].
2. OPERATING TIPS
For optimum scanning results, it is important to properly hold MultiScanner
™
L
550 and move slowly when scanning. The following tips will ensure 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 or tilt the
tool 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.
• Depending on the proximity of electrical wiring or pipes to the wall surface, the
scanner 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 surprises, remember that studs or joists are normally spaced 40 or
60 cm apart and are 38-45 mm in width.
Anything closer together or a
different width may not be a stud, joist, or firebreak.
Always turn off power when working near electrical wires.
SCANNING DIFFERENT SURFACES
Wallpaper:
The MultiScanner
™
L
550 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 the
MultiScanner
™
L
550 to locate studs in StudScan 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
™
L
550 will 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 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
™
L
550 cannot scan for wood studs and joists through carpeting
and pad. In problematic situations, try using Metal Scan to locate nails or
drywall screws that 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 40 and 60 cm stud spacing practices.
3. SELECTING THE MODE
Move selector switch to the desired mode: StudScan for finding wood or metal
studs; DeepScan
®
for scanning walls over 19 mm; Metal Scan for locating
metal; or AC Scan for locating live AC wiring.
Unit will remain off if Power Button is not pressed.
4. TURNING ON/CALIBRATING THE TOOL
MultiScanner
™
L
550 can be calibrated anywhere on the wall. It constantly
monitors the subsurface environment 10 times per second and automatically
recalibrates, when needed, to successfully find the centre of studs in one step.
• Place MultiScanner
™
L
550 against the wall
before
pressing the Power
Button in StudScan or DeepScan
®
.
• 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
®
Pointer 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.
6. WIREWARNING
®
DETECTION
Zircon’s WireWarning
®
detection feature works continuously in StudScan, DeepScan
®
,
and Metal Scan modes. When live AC voltage is detected, the WireWarning
®
detection
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 50 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 StudScan mode (or DeepScan
®
mode on thicker
walls) to quickly locate the centre and edges. Use Metal Scan to determine if the
previous reading in StudScan 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 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 centre 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 Target Indication bars on the screen). If it is a strong target,
the SpotLite
®
Pointer 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 centre 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.
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 centre 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 Target
Indication bars on the screen). If it is a strong target, the SpotLite
®
Pointer 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 centre 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 Mode 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.
Detects other objects besides studs
in StudScan Mode.
Finds more targets than there
should be.
Area of voltage appears much
larger than actual wire (AC only).
Difficulty detecting metal.
Image of metal object appears
wider than actual size.
Constant readings of studs near
windows and doors.
You suspect electrical wires, but do
not detect any.
Flashing Low Battery Indicator and
tool not operating
• Electrical wiring and metal/plastic pipes may be
near or touching back surface of wall.
• Voltage detection can spread on drywall as much as 30 cm
laterally from each side of an actual electrical wire.
• Tool calibrated over metal object.
• Metal targets too deep or small.
• Metal has greater density than wood.
• Double and triple studs are usually found around doors
and windows. Solid headers are above them.
• Wires are shielded by metal conduit, a braided wire layer,
metallic wall covering, plywood shear wall, or other dense
material.
• Wires deeper than 50 mm from surface might
not be detected.
• Wires may not be live.
• Battery level too low for proper operation.
• Scan the area in Metal Scan and AC Scan modes to determine if metal or hot AC is present.
• Check for other studs equally spaced to either side 30, 40, or 60 mm apart or for the
same stud at several places directly above or below the first scan area.
• A stud reading would measure approximately 38-45 mm apart from each edge; any-
thing larger or smaller is most likely not a stud if not near a door or window.
• To narrow detection, turn unit off and on again at the edge of where wire was first
detected and scan again.
• The scanner may have been calibrated over a metal object, reducing sensitivity.
Try calibrating in another location.
• Scan in both horizontal and vertical directions. Metal sensitivity is increased when
metal object is parallel to sensor, located under Zircon logo.
• To reduce sensitivity, recalibrate MultiScanner
™
L
550 over either of first two marks
(Metal Mode only).
• Detect outer edges so you know where to begin.
• Try Metal Scan to see if you can find metal, wire, or metal conduit.
• Use extra caution if the area has plywood, thick wood backing behind drywall, or
thicker than normal walls.
• If a switch controls an outlet, make sure it is ON for detection, but turned off when
working near electrical wires.
Use CAUTION when nailing, sawing, or drilling in walls, floors, and ceilings
where these items may exist.
• Replace with brand new 9V battery.

During scanning, the tool will automatically
recalibrate itself when needed. This recalibration
is usually transparent and no indication is made.
If the tool is initially calibrated near a stud and
then moved away (it will detect the density of
the wall decreasing), an arrow icon will be
illuminated, indicating the direction of the missed stud.
5. FINDING A STUD
Always scan for studs with the scanner placed flat against the wall. Move the mode switch
to StudScan, 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 indication
will illuminate, indicating
location of the stud edge.
Continue sliding tool. When the centre of a stud is
located, the three bars on the Signal Strength Indicator,
the middle segments of the Target Indication bars,
CENTER indication, and SpotLite
®
Pointer will all
illuminate and the buzzer will sound.
In cases of deeper studs (thicker walls), when the centre of
the stud is located only two bars will show on the Signal
Strength Indicator and only the SpotLite
®
Pointer and middle
segments of the Target Indication Bars will illuminate. If you
still cannot locate a stud, try DeepScan
®
mode.
