Zircon StudSensor Pro55 - Edge-Finding Stud Finder Manual

Introduction

BEFORE YOU BEGIN

ZIRCON^® STUD FINDERS WORK BY SENSING DENSITY CHANGES BEHIND THE WALL. OTHER OBJECTS CAN BE DETECTED ESPECIALLY IF THEY ARE VERY CLOSE TO THE WALL. DO NOT ASSUME EVERYTHING DETECTED IS A STUD.

• Always use a new alkaline battery with an extended expiration date at least 3 years beyond current date. Match battery direction to image inside of battery cavity.
• Do not rely exclusively on the scanner to locate items behind a surface. Use other information to help locate such items before penetrating the surface, including construction plans, visible points of entry of pipes and wiring into walls such as in a basement, and standard stud-spacing practices.
• Always start your scan in StudScan Mode which scans through surfaces up to 19 mm deep. Scanning in DeepScan™ Mode may detect an object further behind the wall that may or may not be a stud.
• Always scan for studs at several different heights on the wall and mark the location of every target indicated by the stud finder. This is called "mapping the wall." Pipes and other objects will likely not give consistent readings from floor to ceiling, like a stud would.
• Readings should always be consistent and repeatable.
• Zircon stud finders are recommended for interior use only.
• Studs normally run from floor to ceiling, except above and below windows, and above doors.
• Other objects commonly contained in walls, floors, or ceilings are water pipes, gas lines, firestops, and electrical wiring.- Sensing depth and accuracy can vary depending on scanning environment conditions such as mineral content, moisture, texture and consistency of the wall materials.
• Always turn off power when working near electrical wires.
• 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.
• Studs and joists are normally spaced 40 or 60 cm apart, are normally 38 mm wide, and may be separated by firestops. Anything closer together, or of a different width, may not be a stud or joist.

Overview

2 scanning modes:

• StudScan locates edges of stud (wood or metal) up to 19 mm deep
• DeepScan locates edges of stud up to 38 mm deep

WireWarning Detection automatically detects and alerts for live, unshielded AC (alternating current) wires in both modes. When AC voltage is detected, the WireWarning Detection Indicator shows on display.

INSTALL 9-VOLT BATTERY

Always use a new alkaline battery with an extended expiration date at least 3 years beyond current date. Match battery direction to image inside of battery cavity.

Do not rely exclusively on the scanner to locate items behind a surface. Use other information to help locate items before penetrating the surface, including construction plans, visible points of entry of pipes and wiring into walls such as in a basement, and standard stud-spacing practices.

SELECT MODE / POWER UP

Move Mode Selector Switch to desired mode: StudScan or DeepScan.

To activate tool, press and hold Power Button.
If button is not pressed and held, unit shuts off.

FIND A STUD

For best results, hold the tool as shown (Figure A) and move slowly when scanning.
Do not touch the surface during calibration or scan.

1. Hold tool flat against wall, then press and hold Power Button.
   In 1–2 seconds, the unit will calibrate. A short beep confirms that calibration is complete.
   DO NOT MOVE TOOL DURING CALIBRATION.
2. While holding down the Power Button, slide the tool slowly along the wall. (Figure B)
   
3. When the tool reaches the edge of the stud, all bars show, the SpotLite Pointer will shine, and a steady tone will sound. Mark the spot. (Figure C)
   
4. Without releasing Power Button, continue the scan direction until the Target Indicator Bars and the SpotLite Pointer turn off, then reverse direction. (Figure D)
   
5. Slide tool until the other edge of the stud is detected, and mark this as well. (Figure E)
   The centre of the stud is the midpoint between the two marks.
   

DEEPSCAN MODE

DeepScan Mode will detect studs up to 38 mm deep, or twice the depth of StudScan. Move the Mode Selector Switch to DeepScan Mode, then follow steps 1–5 under FIND A STUD.

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, 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.

OVER-THE-STUD WARNING

If scanning begins directly over a stud, the tool will emit a continual beep and Target Indicator Bars will flash. If this happens, restart the scan in a different location.

WIREWARNING DETECTION

The Zircon^® WireWarning Detection feature works continuously in both modes. When live, unshielded AC voltage is detected, the WireWarning Detection Indicator shows. If scanning begins over a live, unshielded AC wire, the indicator will flash continuously. (Figure F)

Use extreme caution under these circumstances, or whenever live AC wiring is present.

THE TOOL MAY NOT DETECT LIVE CURRENT IF WIRES ARE MORE THAN 50 mm BELOW THE SCANNED SURFACE, IN CONCRETE, ENCASED IN CONDUIT, BEHIND A PLYWOOD SHEAR WALL OR METALLIC WALL COVERING, OR IF MOISTURE IS PRESENT IN THE ENVIRONMENT OR SCANNED SURFACE.

WORKING WITH DIFFERENT MATERIALS
This tool can scan effectively through most sheet materials, including:

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

It is not designed for use with:

• Ceramic tile, slate, granite, marble and other rock surfaces
• 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
• Glass or any other dense material
• Bathroom inserts such as bathtubs and showers
• Surfaces thicker than 38 mm

Wallpaper
This tool 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
It may take a week or longer to dry after application.

Lath and plaster
Due to irregularities in plaster thickness, this tool is not recommended for use on lath and plaster.

Highly 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 DeepScan Mode.

Wood flooring, subflooring, or gypsum drywall over plywood sheathing
Use DeepScan Mode and move the tool slowly.
This tool cannot scan for studs and joists through carpet and padding.

NOTE:
Sensing depth and accuracy can vary depending on scanning environment conditions such as mineral content, moisture, texture and consistency of the wall materials.

Electrical wiring and pipes
Depending on the proximity of electrical wiring or pipes to the wall surface, the tool 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.

Studs and joists
are normally spaced 40 or 60 cm apart, and are 38 mm wide. Anything closer together, or of a different width, may not be a stud or joist.
