Slide the Mode selector switch until you reach |
|
desired scanning mode. The mode can be |
selected with the unit on or off.
CALIBRATING IN STUD SCAN OR STUD DEEPSCAN MODES
Keep unit flat against wall during calibration or scanning.
5 |
Position the TriScanner |
|
flat against the wall. |
Select mode. Press and hold
On/Off button.
SCANNING IN STUD SCAN OR STUD DEEPSCAN MODES
Use Stud Scan mode for depths to about 3⁄4 in. (19 mm) and Stud DeepScan for depths up to 11⁄2 in. (38 mm) or double layers.
7 |
Slowly slide unit |
|
horizontally across wall, |
left or right.
8 When center pair of green LEDs light,
steady tone sounds you have found the stud edge. Mark this spot.
9 Continue holding ON/OFF button in and
scan beyond marked spot until the center green and 3 pairs of red LEDs go out.
10 While holding in button, reverse to locate the other
edge of stud. Mark this second spot. Middle of stud is centered between the two marks.
CALIBRATING IN METAL MODE
11 Select Metal mode. Press and hold ON/OFF button.
Calibrate TriScanner in air, away from metal objects. Position unit flat against wall.
SCANNING IN METAL MODE |
OPERATING CAUTIONS |
|
|
|
|
Metal can be detected up to 11⁄2 in. (38 mm) deep in walls and up to 3 in. (77 mm) deep in concrete.
12 |
While holding in On/Off |
|
button slowly move unit |
on surface to locate targets. |
|
Reverse directions to locate |
|
other edge of target. Lights will |
|
indicate metal in the same way |
|
as in finding studs. When tone |
|
sounds and LEDs light up, you are close to metal. Mark this spot to help ensure that you’re not nailing into a pipe.
CONTINUOUS AC VOLTAGE
DETECTION
13 The TriScanner detects from 90 to 250 V at 50 to 60 Hz AC in a HOT unshielded electrical
wire that is within 11⁄2 in. (38 mm) of wall surface. The voltage detection feature works continuously in all modes. The sensor is located in the center of the back of the unit.
Caution: The TriScanner will not detect hot wires inside metal pipe or metal conduit, behind metallic wall covering, or behind some plywood or other dense materials. Use extra caution in these construction situations. Always turn the power
off when nailing, cutting, or drilling near electrical wires.
VERIFYING IF THE UNIT WORKS
14 |
Turn unit on in the air. |
|
If the LEDs light when |
you bring your hand up to the back, then the unit is working properly.
16 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.
WORKING WITH DIFFERENT MATERIALS
Wallpaper: TriScanner functions normally on walls covered with wallpaper or fabric, unless the materials are metallic foil, contain metallic fibers, or are still wet after application.
Textured Ceilings: When scanning on an uneven surface, place thin cardboard on ceiling and scan over the cardboard. Calibrate with cardboard in place.
Note: TriScanner cannot scan through carpeting and pad or, in most cases, lath and plaster. If you are having difficulty scanning through any of these or other materials, use the Metal mode to locate nails in the stud or joist. Try to locate several nails to get a better idea of how the stud is oriented.
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, pursuant 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 guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined 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:
