Stanley Stud Sensor 100

Product Overview

The Stanley Stud Sensor 100 is an electronic device designed to locate the edges of studs, joists, or live AC wires through common building materials like drywall. It features red LED indicators and an audible tone to signal detection, along with a marking channel for easy marking of stud edges.

Note: The unit automatically shuts off when the activation button is released.

Operating Instructions

Installing the Battery

1. Open the battery compartment on the back of the unit.
2. Connect a 9-volt alkaline battery (Type 6LR61, not included) to the clip.
3. Place the battery back into the case and close the compartment door.

Recommendation: Replace the battery when the low battery indicator (flashing green LED) appears.

Detecting Wood / Metal Studs

1. Hold the Stud Sensor 100 flat against the surface with firm contact.
2. Press and hold the activation button. The green and top red LEDs will illuminate.

3. Note: The unit cannot be moved before calibration is complete.

4. Slowly slide the Stud Sensor 100 across the surface in a straight line. Red LEDs will illuminate as it detects a stud edge.
5. When the stud edge is detected, the top LED will illuminate, and an audible tone will sound. Use the marking channel at the top of the unit to mark the stud edge.
6. Repeat the process from the opposite side of the stud to mark the other edge.
7. The midpoint between the two marks indicates the center of the stud.

Detecting Live AC Wires

1. The live wire red LED will illuminate, and the Stud Sensor 100 will emit an audible tone when in proximity to a live wire (typically within 4" to 18" or 101mm to 457mm along the surface).

Warning! This tool is not a measuring device and should not be used as a substitute for a voltmeter.

Warning! The LED or Live Wire Detection symbol are indicators only and may not accurately indicate the presence of voltage in case of internal device failure or improper operation. Do not rely solely on this feature for identifying hazardous voltages. Always use construction blueprints or visual identification of wiring entry points.

Always turn off AC power when working near wiring. Always follow proper safety practices and use a separate detection method to verify a de-energized condition prior to commencing work.

Surface and Material Considerations

The Stud Sensor 100 scans through common building materials including:

• Gypsum drywall
• Plywood sheathing
• Linoleum over wood
• Wallpaper

The sensor cannot scan through:

• Carpeting
• Foil-faced materials
• Ceramic tile
• Cement or concrete
• Metal & plaster walls

Wallpaper: The function of the Stud Sensor 100 is not affected by wallpaper or fabric unless they contain metallic foil or fibers.

Ceilings: For rough surfaces like sprayed ceilings, use a piece of cardboard when scanning. Calibrate the unit with the cardboard to ensure best performance. Keep your free hand away from the unit.

Note: The thickness, density, and moisture content of the surface material will affect the sensing depth.

Important Safety Notice

• Always hold the Stud Sensor 100 in the handle area only. Grasp between fingers and thumb while making contact with your palm.

• Warning: Shielded wires or wires in metal conduits, casings, metallized walls or thick, dense walls will not be detected.

Operating Tips

• The Stud Sensor 100 is designed for use only on interior surfaces.
• Prevent Interference: To ensure best performance, keep your free hand at least 6 inches away from the unit and wall surface while testing or scanning.
• Static Electrical Charges: Static charges on drywall can spread the voltage detection area. To aid in locating wires, scan holding the unit 1/2" (12mm) away from the wall surface or place your other hand on the surface approximately 12" (304mm) from the sensor.

Conventional Construction

Doors and windows often have additional studs and headers for stability. The Stud Sensor 100 detects the edges of these double studs and solid headers as a single, wide stud.
