If the device indicates live electricity over a large area, you can reduce
the sensitivity of the device to refine the scanning area and more
accurately locate the live AC wiring by following steps 2 and 3.
2.
(Figure B) To further pinpoint the location of the live AC wiring, scan
the area again.
Release the Scan button and then turn the device back on, this time
starting on the wall over one of the previous marks. This will reset the
device to a lower sensitivity and narrow the scan area.
3.
(Figure C) Scan in both directions as in Step 2. The area indicated
should become smaller so you can more precisely identify the location
of live AC wires. This procedure can be repeated multiple times to
narrow the field even further. Scan in the opposite
direction and mark
the peak highest point to accurately locate the AC position.
Note
: If any bars display on the screen, AC voltage is present. Small
targets or targets deep within the surface may only illuminate some of the
bars and not the center line or audio tone. In this case, use the highest
indication to determine the AC position.
Note
: AC Scan will only detect live (hot) unshielded AC wiring. Please refer
to the
WARNING statement in
chapter 12, AC wire warning, for more
important details and warnings about AC detection.

AC wire warning
AC warning
detection feature works continuously in Stud 1⁄2 in

, Stud 1 1⁄2 in

Scan modes, and Metal Scan Mode. When live AC
voltage is detected, the AC detection warning indicator will appear in the
display. If scanning begins over a live AC wire, the AC Wire Warning will
show continuously. Use extreme caution under these circumstances or
whenever live AC wiring is present.
WARNING Electrical field locators may not detect live AC wires if
wires are more than 2 in. (51 mm) from the scanned surface, in
concrete, encased in conduit, present behind a plywood shear wall
or metallic wall covering, or if moisture is present in the
environment or scanned surface.
DO NOT ASSUME THERE ARE NO LIVE ELECTRICAL WIRES IN THE
WALL. DO NOT TAKE ACTIONS THAT COULD BE DANGEROUS!
IF THERE IS AN ACTIVE ELECTRICAL WIRE IN THE WALL. ALWAYS
TURN OFF THE ELECTRICAL POWER, GAS, AND WATER SUPPLIES
BEFORE PENETRATING A SURFACE. FAILURE TO FOLLOW THE
INSTRUCTIONS MAY RESULT IN ELECTRIC SHOCK, FIRE, AND/OR
SERIOUS INJURY OR PROPERTY DAMAGE.
