Stud Sensor Information
The Stud Sensor CMHT77620/CMHT77621 uses electronic signals
to locate the center of wood or metal studs, or live AC wires
through drywall or other common building materials.
PLEASE NOTE:
• The stud sensor will not detect objects in concrete, mortar,
block, brick work, plaster, carpeting, foil- faced materials,
metallic surfaces, or ceramic tile.
• The stud sensor is not designed to locate non-ferrous or plastic
objects, such as pipes.
Once the center of a wood or metal stud has been detected in one
pass across the surface, the Stud Sensor CMHT77620/CMHT77621
turns on an LED and sounds an audible tone. A marking hole
allows you to easily note the stud center

the warnings and instructions in this manual may
result in serious personal injury.
SAVE THESE INSTRUCTIONS
WARNING:
The following label information can be found on your tool
for your safety.
CAUTION:
Protect your eyes. Wear safety goggles.
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 on the display
is just an indicator and in some situations the voltage
detection option may not accurately indicate the
presence of voltage in a wall in the event of internal
device failure or improper operation, and therefore
should not be solely 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 follow proper safety practices and use a
separate detection method to verify a de-energized
condition prior to commencing work.
WARNING:
Always turn off AC power when working near wiring.
WARNING:
Shielded wires or wires in metal conduits, casings,
metalized walls, or thick, dense walls may not be
detected.
