Zircon MultiScanner i520 OneStep - Multifunction Wall Scanner Manual

INTRODUCTION

This MultiScanner^™ i520 OneStep^™ features four scanning modes:

STUD SCAN: Locates the center and edges of wood and metal studs up to 19 mm deep
STUD DEEPSCAN ™: Locates the center of wood and metal studs up to 38 mm deep
METAL SCAN: Detects and locates ferrous (magnetic) metal (such as 13 mm rebar) up to 76 mm deep and non-ferrous (non-magnetic) metal up to 38 mm deep
AC SCAN: Detects and locates live unshielded AC wires up to 51 mm deep

WireWarning ™ detection automatically detects and alerts of live AC wires in STUD SCAN, STUD DEEPSCAN ™, and METAL SCAN modes. When AC voltage is detected, the AC WireWarning ™ icon will be displayed on screen.

warning Note: This product is intended only for use with an optimum voltage range of 110–127 V.

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.

OPERATING TIPS

For optimum scanning results, it is important to properly hold the MultiScanner^™ i520 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.

PARTS AND FEATURES

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^™ i520 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 ™ i520 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 ™ i520 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 ™ i520 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.

warning 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.

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.

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.
FINDING A STUD

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 ™ Pointing System and four Middle bars will illuminate. If you still cannot locate a stud, try STUD DEEPSCAN ™ mode. In STUD DEEPSCAN ™ mode, the Stud icon will continuously flash.

CALIBRATING THE TOOL IN STUD SCAN/STUD DEEPSCAN™ MODE

MultiScanner ™ i520 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 ™ i520 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.

warning 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.
ACT ™ (Auto Correcting Technology)

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.

SCANNING IN METAL MODE

warning 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.

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.)
(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.
(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.
(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 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.

SCANNING IN AC MODE

As with METAL SCAN Mode, AC SCAN Mode has interactive calibration and works in the same manner.

(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^TM 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.
(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.
(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.

warning 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.

HELPFUL HINTS

(See also number 2, Operating Tips)

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 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.
Area of voltage appears much larger than actual wire (AC only).	Voltage detection can spread on drywall as much as 31 cm laterally from each side of an actual electrical wire.	To narrow detection, turn unit off and on again at the edge of where wire was first detected and scan again.
Difficulty detecting metal.	Tool calibrated over metal object. Metal targets too deep or small.	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 ™ i520 over either of first two marks (Metal mode only).
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 are shielded by metal conduit, a braided wire layer, or metallic wall covering. Wires deeper than 51 mm from surface might not be detected. Wires may not be live.	Try METAL SCAN mode to see if you can find metal, wire, or metal conduit. Try turning on switches to outlet. Try plugging a lamp into outlet and turning on switch.
Unit flashes and beeps 6 times, then LCD display remains blank with backlit screen on.	Low battery.	Replace with new battery.
