1. INSTALLING THE BATTERY
Push in the battery door tab at the bottom of the tool and open
the door. Insert a
new
9-volt 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 9-volt battery with
a brand new battery immediately.
2. OPERATING TIPS
For optimum scanning results, it is important to properly hold
the MultiScanner
®
HD
800
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
the handle 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.
• 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 16 or 24 in. (41 or 61 cm) 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 power when working near electrical wires.
SCANNING DIFFERENT SURFACES
Wallpaper:
MultiScanner
®
HD
800 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 MultiScanner
®
HD
800 to locate studs in Stud
modes. Change to Metal Scan mode to locate the nail heads
holding wood lath to the studs. If the plaster has metal mesh
reinforcement, MultiScanner
®
HD
800 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 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
®
HD
800 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.
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.
3. SELECTING THE MODE
Move selector switch to the desired mode: StudScan for finding wood or metal
studs; DeepScan
®
for scanning walls over
3
⁄
4
in. (19 mm) thick; or Metal Scan for
locating metal.
Unit will remain off if Power button is not pressed.
4. TURNING ON/CALIBRATING THE TOOL
MultiScanner
®
HD
800 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
®
HD
800 against the wall
before
pressing the Power button in
StudScan or 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
®
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.
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.
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.

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 center 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
center 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.
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 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.
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 center 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 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
®
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 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.

Multifunction Wall Scanner
Detects other objects besides studs
in StudScan 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 to determine if metal is present.
• Check for other studs equally spaced to either side 12, 16, or 24 in. (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 1
1
