Troubleshooting - Greenlee SF-530 Manual De Instrucciones

3. Continue tracing by watching for the same indication as you move along
other areas of the wall.
The SF-530 detects from 90 V to 250 V at 50 Hz to 60 Hz AC in a hot electrical
wire. The voltage detection feature works continuously in all modes for safety.
Working with Different Materials
• Wallpaper: The unit functions normally on walls covered with wallpaper or
fabric, unless the materials are metallic foil, contain metallic fibers, or are still
wet after application.
• Lath and plaster: Due to irregularities in plaster thickness, it is difficult for
the unit to locate studs in Stud Scan mode. Change to Metal mode to locate
nail heads holding laths to stud. If plaster has metal mesh reinforcement, the
unit will be unable to detect anything through that material.
• Acoustic ceilings: When scanning ceiling with uneven surface, place thin
cardboard on ceiling and scan over the cardboard using DeepScan mode.
Calibrate with cardboard in place.
• Wood flooring, subflooring, or gypsum drywall over plywood sheathing: Use
DeepScan mode.
• The unit cannot scan for wood studs and joists through ceramic floor tile or
carpeting and pad.
• In problem situations, try using Metal mode to locate nails or drywall screws
that line up vertically where a stud is positioned.
Note: Sensing depth and accuracy can vary due to moisture content of
materials, wall texture, and paint.

Troubleshooting

Situation
Flashing Display!
Error Indicator
Working in DeepScan mode and
can't detect studs.
Detects other objects besides
studs in Stud Scan and DeepScan
modes.
Finding more targets than there
should be.
Area of voltage appears much
larger than actual wire (AC only).
Center arrow doesn't appear on
LCD.
Difficulty detecting metal.
Image of metal object appears
wider than actual size.
Constant readings of studs near
windows and doors.
You suspect electrical wires, but
do not detect any.
Low Battery Indicator.

Probable Causes
• Scan began on dense part of wall or over a
stud.
• Unit not flat against wall.
• Unit tilted or lifted during scan.
• You may have calibrated over a stud.
(DeepScan mode is very sensitive. The error
condition has been disabled in this mode.)
• You may be holding the unit like a TV remote,
aiming it at the wall.
Electrical wiring and metal or plastic pipes may
be near or touching back surface of wall.
Static charge may develop on drywall, spreading
voltage detection as much as 305 mm (12")
laterally from each side of an actual electrical
wire.
Wall is particularly thick or dense.
• Unit not properly calibrated.
• Metal targets too deep.
Metal has greater density than wood.
Double and triple studs are usually found
around doors and windows. Solid headers are
above them.
• Wires may be shielded in metal conduit or
behind metallic wall covering.
• Wires deeper than 51 mm (2") from surface
might not be detected.
• Wires may not be hot.
Battery is running out.

Metal Scan Mode: Up to 38 mm (1-1/2") for copper; up to 76 mm (3") for
rebar
Note: Sensing depth and edge detection can vary due to moisture content
of materials, wall texture, paint, etc.
AC Position Accuracy: Typically 90 V to 250 V at 50 Hz to 60 Hz within 150 mm
(6") of a hot unshielded wire
AC Depth: Typically 50 mm (2")

Humidity: 80% RH (noncondensing)
Solutions
• Turn unit off, move over a few inches, press On/Off button, and start
again.
• On rough surfaces, place thin cardboard on wall, scanning through it to
help slide unit more smoothly.
• Always hold unit parallel to and move perpendicular to object you're
trying to locate.
• Move unit over a few inches and recalibrate.
• Hold unit so two Velcro™ strips on the back make contact with wall.
• Switch to Metal mode, where combined with Continuous AC detection,
pipes and electrical wiring should be detected adequately.
• Check for other studs equally spaced to either side at 305 mm, 406 mm,
or 610 mm (12", 16", or 24") or the same stud at several places directly
above or below the first.
• Use caution when nailing, cutting, or drilling in walls, floors, and
ceilings where these items may exist.
• To narrow detection, turn unit off and on again at the edge of where wire
was detected and scan again.
• Place your free hand flat against wall near tool to drain static.
• Interpret the pair of LCD bars closest to center as stud edge.
• Switch to DeepScan, where more bars may appear, to locate the stud.
• Always calibrate in air for best sensitivity and to avoid calibrating over
any metal.
• Scan in both horizontal and vertical directions. Metal sensitivity is
increased when metal object is parallel to sensor, located at front end of
unit beneath crosshair.
To reduce sensitivity, recalibrate unit over either of first two marks.
Detect outer edges so you know where to begin.
• Try Metal scan to see if you can find metal, wire, or metal conduit.
• Always turn off the power when working near electrical wires.
• Try turning on switches to outlet.
• Try plugging a lamp into outlet and turning on switch.
Replace battery.
