Zircon MultiScanner i320 OneStep - Multifunction Wall Scanner Manual

INSTALLING THE BATTERY

Press battery door release in with your finger or a coin and lift up to remove door. Connect 9-volt battery to cable. Place into the compartment and press into place. Replace battery door and snap shut. Battery will last approximately 2 years under normal conditions.

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; or METAL SCAN for locating metal.

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 with 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.

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 can't locate a stud, try STUD DEEPSCAN^® mode.

OPERATING TIPS

For optimum scanning results, it is important to properly hold the MultiScanner^® i320 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.

WireWarning^® Detection

Zircon's WireWarning^® detection feature works continuously in all 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. If this occurs, release the Power button, move the tool over, and recalibrate in a new location. Once calibration has completed, begin to slide the tool in the direction of your initial calibration.

Wires deeper than 51 mm from the surface, in plastic conduit, or behind plywood shear wall, or metallic wall covering may not be detected. Metal shielded wires or those in metal conduit will not be detected. Use extreme caution under these circumstances or whenever live AC wiring is present.

Always turn off power when working near electrical wires.

CALIBRATING THE TOOL IN STUD SCAN/STUD DEEPSCAN^®

MultiScanner^® i320 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^® i320 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.
  

WORKING WITH DIFFERENT MATERIALS

Wallpaper: The MultiScanner^® i320 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 the MultiScanner^® i320 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^® i320 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 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^® i320 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.

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 of wood or metal studs. 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 that allows you 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 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.
   

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.
