Zircon StudSensor HD55 - Stud Finder Manual

The StudSensor^™ HD55 features two scanning modes:

• StudScan: Locates the edges of wood and metal studs up to 19 mm deep
• DeepScan^®: Locates the edges of wood and metal studs up to 38 mm deep

WireWarning^® detection automatically detects and alerts the user to live AC wires in StudScan and DeepScan^® modes. When AC voltage is detected, the AC WireWarning^® icon will be displayed on screen.

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.

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 brandnew one, or contact your Zircon dealer or e-mail at techsupport@zircon.com.

OPERATING TIPS

For optimum scanning results:

• 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.
• 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.

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 tool's sensors. Please allow a few days for the wall to dry out.

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.

Always turn off the power when working near electrical wires.

WORKING WITH DIFFERENT MATERIALS

StudSensor^{™ HD}55 is for use on dry interior walls only.

Note: Sensing depth and accuracy can vary due to moisture, content of materials, wall texture, and paint.

StudSensor^{™ HD}55 can scan effectively through most sheet materials, including:

• Bare wood flooring (in DeepScan^® mode)
• Linoleum on wood base
• Gypsum drywall over plywood sheathing
• Wallpapered walls (if dry)
• Textured ceilings if uniform thickness (place a thin piece of cardboard on ceiling and scan over it to avoid damage to texturing)

StudSensor^{™ HD}55 is not designed to scan materials such as:

• Ceramic floor tile
• Carpeting and padding
• Wallpaper with metallic fibres
• Freshly painted walls that are still damp (may take one week or longer to dry after application)
• Lath and plaster walls
• Foil covered insulation board
• Glass or any other dense material

SELECTING THE MODE

Move selector switch to the desired mode:

StudScan for finding wood or metal studs or DeepScan^® for finding studs behind walls more than 19 mm thick.

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 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.

Continue to hold the Power button, then slowly slide unit horizontally across the wall, left or right. As you begin to approach a stud, the outer Target Indication bars will begin to turn on.

When the full Target Indication bars are first displayed across the display, the SpotLite^® Pointer and Target Spotlight shine, and a steady tone sounds, you have located the edge of the stud. Mark this spot.

Without releasing Power button, continue scanning beyond marked spot until some Target Indication bars turn off. Slide unit in reverse direction to locate other edge of stud.

Mark this second spot. Centre of stud is midway between the two marks.

WIREWARNING^® DETECTION

WireWarning^® detection works continuously in StudScan and DeepScan^® modes. When live AC voltage is detected, the WireWarning^® indicator will appear on the display. If scanning begins over a live AC wire, the WireWarning^® indicator will flash continuously. Use extreme caution in these circumstances or whenever live AC is present.

Electrical field locators may not detect live AC wires if moisture is present in the wall, or if wires are more than 50 mm from the scanned surface, in plastic conduit or behind a plywood shear wall or metallic wall covering.

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.
