Selecting Scanner Depth Mode:
• Depress and hold activation button once (1x) to select to 1/2" (12mm) read depth detection.
The 1/2" (12mm) mode LED will illuminate.
• Double click (depress two times - 2x) and hold activation to select to 1" (25mm) read depth
detection.The 1" (25mm) mode LED will illuminate.
• Triple click (depress three times - 3x) and hold activation button to select 1-1/2" (38mm) read
depth detection.The 1-1/2" (38mm) mode LED will illuminate.
Note: For best results the depth mode selected should be based on the thickness of the surface
material being scanned.
Note: The unit cannot be moved before calibration is complete.
• When the red LED goes off, the unit is calibrated.
• Keep holding the activation button during all of the following procedures.
Note: Once the activation button is released, the unit shuts off.
• If the red LED stays lit, move the Stud Sensor 150 to a different location and try again.Releasing
the activation button will turn off the sensor.
Note: While calibrating, the Stud Sensor 150 must not be placed directly over a stud, dense
material such as metal, or over a wet or newly painted area, or it will not properly calibrate.
• Slide the Stud Sensor 150 slowly across the surface in a straight line.As it detects a stud, the red
LED's will go on.
2)When it detects the stud edge, the top LED will go on and an audible tone will sound. Use the
marking notch located at the top of the unit to mark the stud edge.
3-4) Repeat the above steps from the other side of the stud. Coming from the opposite direction,
mark the other edge of the stud.
• The midpoint of the two marks indicates the stud center.
Detecting Live AC Wires
The live wire red LED will illuminate and the Stud Sensor 150 sounds an audible tone, warning
when in the proximity (typically within 4" (10cm) to 18" (46cm) along the surface) of a live wire.
Warning! This tool is not a measuring device and should not be used as a substitute for a
voltmeter.
Warning! The live wire red LED on the display is just an indicator and in some situations
the voltage detection option may not accurately indicate the presence of voltage in the event
of internal device failure or improper operation, and therefore should not be relied upon for
identification of the presence of hazardous voltages. Other evidence such as construction
blueprints or visual identification of wiring or conduit entry points should also be utilized.
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.
Note: Static electrical charges that can develop on drywall and other surfaces will spread the
voltage detection area many inches on each side of the actual electrical wire. To aid in locating the
wire position, scan holding the unit ½" (12mm) away from the wall surface or place your other
hand on the surface approximately 12" (30cm) from sensor.
Warning: Shielded wires or wires in metal conduits, casings, metallized walls or thick, dense walls
