Zircon StudSensor L40 Manual

INTRODUCTION

INSTALLING THE BATTERY

Push in the battery door tab at the bottom of the tool and open the door. Insert a new 9 V battery, matching the positive (+) and negative (-) terminals to the icons printed on the back. Snap the battery into place and replace the door.

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 16 or 24 in. (41 or 61 cm) apart and are 11⁄2 in. (38 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 16 and 24 in. (41 and 61 cm) stud spacing practices.

Always turn off the power when working near electrical wires.

WORKING WITH DIFFERENT MATERIALS

StudSensor^™ L40 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^™ L40 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^™ L40 is not designed to scan materials such as:

• Ceramic floor tile
• Carpeting and padding
• Wallpaper with metallic fibers
• 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:
STUD SCAN for finding wood or metal studs or DEEPSCAN^® for finding studs behind walls more than 3⁄4 in. (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 STUD SCAN, place the tool flat against the wall, then press and hold the Power button. Do not move the unit until calibration is complete. When calibration is complete, the green READY light will illuminate.

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 arrow segments will begin to turn on.

When the top red EDGE light is lit, the SpotLite^® pointer shines, and a steady tone sounds, you have located the edge of the stud. Mark this spot.

Without releasing the Power button, continue scanning beyond the marked spot until the red EDGE light turns off. Slide unit in reverse direction to locate other edge of stud.
Mark this second spot. Middle of stud is centered between the two marks.

WIREWARNING^® DETECTION

WireWarning^® detection works continuously in STUD SCAN and DEEPSCAN^® modes. When live AC voltage is detected, the WireWarning^® light comes on. 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 wires are more than 2 in. (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.
