Electronic Stud Sensor.
Installing the Battery
With a small tool or coin, slide the pocket clip up and off of
Insert a 9-volt battery so that the minus (-) sign on the battery
matches the minus (-) sign on the side of the battery compartment.
Slide the pocket clip on to the case and press it down hard until
it snaps closed.
Scanning for Studs
Place the iSensor against the wall with the pocket clip near the
palm of your hand and your fingers no higher than the word "Zircon"
(see Figure 1).
Keeping your other hand at least 6 inches away from the iSensor,
press and HOLD in the ON/OFF switch located on the left side of
Slide the iSensor slowly across the wall, left or right, until the
LED comes on and stays on. This is the stud edge. Mark this spot.
Continue moving across the stud until the LED turns off and then,
still holding the switch in, reverse direction and locate the other
edge of the stud and mark it in the same way.
The midpoint of the two marks is the center of the stud.
1. The position where you start is important. iSensor finds
dense objects beneath the wall surface. To work right, the tool
must start (by holding the button) over a part of the wall that
is not dense. If iSensor seems weak or inconsistent, try starting
at a new spot some distance to either side of the first. iSensor
will not work if started directly over a stud, metal, wet paint
or wet wallpaper.
2. iSensor will only detect the outer edge of double studs
and headers around doors, windows and corners.
3. iSensor usually finds studs but can some-times find pipes
or other objects. Be sure you've found a stud by finding other
studs equally spaced to either side (16 or so inches apart),
and finding the same stud at several places directly above and
below the first.
You can check that your iSensor is working by holding it in
one hand and pressing in on the ON/OFF switch. While holding
the switch in, bring the palm of your other hand up against
the back of the iSensor. The LED should turn on. If it does
not, try replacing the battery.
Double Stud & Solid Headers: These supporting members are
usually found around doors, windows and corners. The iSensor
will only detect the outer edge of this grouping.
If electrical wiring, metal or plastic pipes are close to or touching
the inside surface of the wall, the iSensor may detect them in the
same manner as studs. Caution should always be used when nailing,
cutting, or drilling into walls, floors, and ceilings that may contain
To avoid surprises, remember that studs are normally spaced 16 inches
or 24 inches apart on center and are 1-1/2 inches in width. Anything
closer together or a different width may not be a stud, or fire
Note: Always turn off the power if working near electrical
