AC WireWarning™

StudSensor™ Pro SL-AC Stud Finder

with AC WireWarning™ and

SpotLite® Pointing System

WORKING WITH DIFFERENT MATERIALS

StudSensor Pro SL-AC is for use on dry, interior walls only. Although StudSensor Pro SL-AC can scan through up to

11⁄2 in. (38 mm) of common construction materials in DeepScan mode, three pri- mary factors can affect sensing depth: thickness, density, and moisture content.

StudSensor Pro SL-AC can scan effectively through most sheet materials, including:

The Zircon StudSensor™ Pro SL-AC detects wood and metal studs and joists in walls, floors, and ceilings. It features two scanning modes, recessed LEDs, a durable high-impact case, and the patented SpotLite® Pointing System. It also has WireWarning™

to continuously detect hot AC voltage in both modes.

INSTALLING THE BATTERY

1	Squeeze sides of
	clip to help
release clip end.
2	Slide 9-V battery
	into compartment,

terminal side first, matching (+) and (–) terminals from battery to case.

When the top green LED is lit, a steady

tone sounds, and the SpotLite® shines, you have located the edge of the stud. Mark this spot.

•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 through it to avoid damage

to texturing.)

StudSensor Pro SL-AC is not designed to scan materials with inconsistent density such as:

•Ceramic floor tile

•Carpeting and padding

•Wallpaper with metallic fibers

•Freshly painted walls that are still damp (must dry at least a week)

•Lath and plaster walls

•Foil covered insulation board

FCC Part 15 Class B Registration Warning

This equipment has been tested and found to comply with the limits for a Class B digital device, pur- suant to Part 15 of FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the

equipment is operated in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with

the instructions, may cause harmful interference to radio communications. However, there is no guar- antee that

interference will not occur in a particular installation. If

this equipment does cause harmful interference to radio or television reception, which can be deter- mined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

(1)Reorient or relocate the receiving antenna.

(2)Increase the separation between the equipment and receiver.

(3)Connect the equipment into an outlet on a circuit, different from that which the receiver is connected (if applicable).

3	Replace the clip.
	Battery will last

approximately two years under normal conditions.

CALIBRATION AND SCANNING IN STUD SCAN OR DEEPSCAN® MODES

Note: Unit calibrates on each use.

Use Stud Scan Mode for depths to about 3⁄4 in. (19 mm) and DeepScan for depths up to

11⁄2 in. (38 mm) or double layers.

Note: Keep unit flat against wall. Do not lift or tilt unit during calibration or scanning.

4	Slide the Mode Selector
	switch to the desired
scanning mode. The mode can
be selected with the unit on
or off.
5	With StudSensor Pro SL-AC
	turned off, position the unit
flat against the wall.
6	Without moving unit, squeeze
	and hold On/Off button.
TruCal® LED should be lit.
7	Continue to hold
	in the On/Off
button then slowly slide
unit horizontally across
the wall, right or left.
8	As you begin to approach a stud, the red LEDs
	will light successively, from bottom to top.

10 Continue scanning beyond marked

spot until green LED goes out. Slide unit in reverse direction to locate other edge of stud.

11 Mark this second spot. Middle of stud

is centered between the two marks.

CONTINUOUS AC VOLTAGE DETECTION (WireWarning™)

12 The StudSensor Pro SL-AC detects from 90 to 250 V at 50 to 60 Hz

AC in a hot electrical wire. The voltage detection feature works continuously in both Stud Scan and DeepScan modes. When sensing voltage, the small AC light comes on.

Caution: The StudSensor Pro SL-AC will not detect hot wires inside metal pipe or conduit, behind metallic wall covering, or behind some plywood or other dense materials. Use extra caution in these situations. Always turn the power off when nailing, cutting, or drilling near electrical wires.

OPERATING CAUTIONS

13	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 in. (406 mm) or 24 in. (610 mm) 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. Always turn off the power when working near electrical wires.

(4)Consult the dealer or an experienced radio/TV technician for help.
