MultiScanner i700
Multifunction Wall Scanner
Congratulations on purchasing the most technically advanced wall
scanner ever created! Zircon introduced the StudSensor in 1980 and has
put over 25 years of research into developing OneStep, the advanced
technology at the core of the MultiScanner i700. OneStep technology
senses, processes and adapts to wall surfaces to provide high-definition
visibility into walls, floors and ceilings. MultiScanner i700 is the fastest,
most accurate and easiest-to-use wall scanner on the market today.
1. INSTALLING THE BATTERY
Press battery door release in with your finger or a coin and lift up to
remove door.
Place 9V battery into the compartment and press into place.
Replace battery door and snap shut. Battery will last approximately 2
years under normal conditions.
2. SELECTING THE MODE
Move selector switch to the desired mode: STUD SCAN for finding wood
or metal studs; METAL SCAN for locating metal; or AC SCAN for locating
hot AC wiring.
Move selector switch to the OFF position when not in use to prevent the
tool from accidentally powering on and wearing down the battery.
3. FINDING A STUD
Always start with the scanner placed against the wall, then press the
handle down. Wait for beep to confirm calibration has completed before
moving tool.
Slowly slide tool across surface. EDGE
display will illuminate, indicating location
of the stud edge.
Continue sliding tool. When the centre of
the stud is located with three bars on the
Signal Strength Indicator, the buzzer will
sound and the four middle bars, CENTRE
display and SpotLite will illuminate.
In cases of deeper studs (or thicker walls)
two bars will show on the Signal Strength
Indicator and only the SpotLite and four
middle bars will illuminate. If you still can’t
locate a stud, try the next step.
Quickly (within one second) release and
re-press the handle down. The scanner
will enter the
High Sensitivity Mode
and
the Stud Scan Mode Indication will flash
continuously. The centre of a very deep
stud will be indicated by the four middle
bars illuminating.
4. TIPS FOR PROPER OPERATION
For optimum scanning results it is important to
properly hold MultiScanner i700 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.
• Make sure your other hand or any other part of
your body is not touching the surface being
scanned. This could interfere with the tool’s
performance.
5. CALIBRATING THE TOOL
MultiScanner i700 is the world’s first StudSensor that can be calibrated
anywhere on the wall.
• Place MultiScanner i700 against the wall and press the handle until it
lays flat against the wall. Pressing the tool to lay flat against the wall will
automatically power on the tool via the internal on/off switch.
• Once powered on, tool will automatically perform all calibrations. The
LCD will display all icons until calibration is complete. Upon completion
of calibration, the SpotLites and buzzer will momentarily activate and the
tool will begin continuous measurements. Continue to press 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.
• One of the most important factors in ensuring scanning accuracy is
calibrating the tool away from a stud, so the tool will sense increased
density over the stud. 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 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.
6. SCANNING IN METAL MODE
Press the tool flat against the wall and slowly slide the scanner across
the surface. MARK the spot where the display bars peak and the steady
tone sounds. The SpotLites will also shine a beam of light. 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 metal object.
7. SCANNING IN AC MODE
Press the tool flat against the wall and slowly slide the scanner across
the surface. MARK the spot where the display bars peak and the steady
tone sounds. The SpotLites will also shine a beam of light. 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 electrical object.
Note: AC SCAN mode will only detect hot AC wiring.
AC WireWarning
Zircon’s AC WireWarning feature works continuously in all modes. When
AC voltage is detected, the AC Alert warning icon will appear in the
display.
CAUTION: Wires deeper than 2 inches (51mm) from the surface, in
conduit, or behind plywood shear wall may not be detected. Use extreme
caution under these circumstances or whenever hot AC wiring is present.
Always turn off power when working near electrical wires.
8. WORKING WITH DIFFERENT MATERIALS
Wallpaper:
The MultiScanner i700 functions normally on walls covered
with wallpaper or fabric, unless the materials are metallic foil, contain
metallic fibres or are still wet after application.
Lath and Plaster:
Due to irregularities in plaster thickness, it is difficult
for the MultiScanner i700 to locate studs in STUD SCAN mode. Change
to METAL SCAN mode to locate nail heads holding laths to stud. If plaster
has internal mesh reinforcement, MultiScanner i700 will be unable to
detect through that material.
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. Calibrate with cardboard in place.
Wood flooring, subflooring or gypsum drywall over plywood
sheathing:
Use STUD SCAN 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 i700 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 stud is
positioned.
Note: Sensing depth and accuracy can vary due to moisture content of
materials, wall texture and paint.
9. MARKING THE LOCATION
Once an object is located, you can MARK the location by gently pulling
down the MARK button with the tip of your finger. Pulling back the MARK
button will cause a pencil point to extend from the front of the handle,
placing a short erasable line on the wall.
10. CHANGING THE MARKER TIP
Pull and hold the MARK button to fully extend the marker tip. Grasp the
marker and pull it off the marker post. To install a new marker tip, pull and
hold the MARK button to fully extend the marker post. Push the new
marker onto the marker post.
Note: MultiScanner i700 comes with three spare marker tips. These tips
are stored in a compartment behind the battery.
11. REMOVING OR REPLACING THE SCANNING HEAD
MultiScanner i700’s scanner head may be removed from the handle to
facilitate cleaning or repair. Or the scanning head may also become
separated from the handle if accidentally dropped or twisted. Follow the
directions below to replace the scanning head:
To remove head:
Place the back of the head in the palm of one hand
and grasp the body of the unit in the other hand. Slowly and gently lift
and turn the body, removing one arm from the socket at a time.
To replace the head:
Align the end of the arms over the sockets and
gently snap them back into their sockets, one arm at a time.
12. HELPFUL HINTS
(See also number 4, Tips for Proper Operation)
Situation
Probable Cause
Solution
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 the wall.
• Scan the area in METAL and AC SCAN modes to
determine if metal or hot AC is present.
• Check for other studs equally spaced to either side (12, 16
or 24in [305, 406 or 610mm]) apart or the same stud at
several places directly above or below the first.
Use CAUTION when nailing, sawing or drilling in walls, floors and
ceilings where these items may exist
Area of voltage appears
much larger than actual wire
(AC only)
• Static charge may develop on dry
wall, spreading voltage detection as
much as 12in (305mm) laterally from
each side of an actual electrical
wire.
• To narrow detection, turn unit off and on again at the edge
of where the wire was first detected and scan again.
• Place your free hand flat against the wall near the tool
during the entire scan to drain static.
Difficulty detecting metal
• Tool calibrated over metal object.
• Metal targets too deep.
• 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.
Image of metal object
appears wider than
actual size
• Metal has greater density than wood
• To reduce sensitivity, recalibrate MultiScanner i700 over
either of the first two marks.
Constant readings of studs
near windows and doors
• Double and triple studs are usually
found around doors and windows.
Solid headers are above them.
• Detect outer edges so you know where to begin.
You suspect electrical wires
but do not detect any.
• Wires may be shielded in metal
conduit or behind metallic wall
covering.
• Wires deeper than 2in (51mm) from
surface might not be detected.
• Wires may not be hot.
• Try METAL SCAN to see if you can find metal, wire or
metal conduit.
• Always turn off the power when working near electrical
wires.
• Try turning on switches to outlet.
• Try plugging a lamp into outlet and turning on switch.
