Zircon StudSensor L70 Manual

BEFORE YOU BEGIN
ZIRCON STUD FINDERS WORK BY SENSING DENSITY CHANGES BEHIND THE WALL. OTHER OBJECTS CAN BE DETECTED
ESPECIALLY IF THEY ARE VERY CLOSE TO THE WALL. DO NOT ASSUME EVERYTHING DETECTED IS A STUD.
- Always use a new 9V alkaline battery with an extended expiration date at least 3 years beyond the current date.
Match battery direction to images inside of battery cavity.
- Do not rely exclusively on the scanner to locate items behind a surface. Use other information to help locate such items
before penetrating the surface, including construction plans, visible points of entry of pipes and wiring into walls such as
in a basement, and standard stud-spacing practices.
- Always start your scan in StudScan Mode which scans through surfaces up to 19 mm deep. Scanning in DeepScan
Mode may detect an object further behind the wall that may or may not be a stud.
- Always scan for studs at several different heights on the wall and mark the location of every target indicated by the
stud finder. This is called "mapping the wall." Pipes and other objects will likely not give consistent readings from floor
to ceiling, like a stud would.
- Readings should always be consistent and repeatable.
- Zircon stud finders are recommended for interior use only.
- Studs normally run from floor to ceiling, except above and below windows, and above doors.
- Other objects commonly contained in walls, floors, or ceilings are water pipes, gas lines, firestops, and electrical wiring.
- Sensing depth and accuracy can vary depending on scanning environment conditions such as mineral content, moisture,
texture and consistency of the wall materials.
- Always turn off power when working near electrical wires.
- 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.
- Studs and joists are normally spaced 40 or 60 cm apart on centre, are normally 38 mm wide, and may be separated
by firestops. Anything closer together, or of a different width, may not be a stud or joist.

LIKELY CAUSE
• Hold the tool with thumb on one side and fingers on the other side. Do not
touch the surface being scanned or the scanning head of the tool.
• Move the tool straight up and down, parallel to the studs. Do not rotate
the tool.
• When scanning an uneven surface, place thin cardboard on the surface
to be scanned and scan over the cardboard in DeepScan
• With tool on, quickly release and re-press the Power Button to enter
DeepScan
If you are using tool on a recently taped, painted, or wallpapered wall, allow
time to dry and try again.
Check for other studs equally spaced to either side at 30, 40, or 60 cm, or
check for the same stud at spots directly above or below the first scan area.
Studs will run straight up and down, from floor to ceiling, while pipes
may change direction. Standard studs measure approximately 38 mm
between edges. Anything larger or smaller is likely not a stud (unless near
door or window).
Narrow the scan detection: 1. Turn tool off. 2. Turn it on again at the edge of
where the wire was first detected. 3. Repeat scan.
If there is an outlet switch, turn it to ON position while scanning, but turn
OFF when working near the wires. Use extra caution if the area
has plywood, thick wood backing behind drywall, or walls that are
thicker than normal.
See above.
Plug a lamp into the outlet and turn it on to test whether wires are live.
Install a new 9V alkaline battery with an extended expiration date.
