Locating the Break in an Open Line
The 2011 is unable to find opens in metal shielded flexible or rigid metal conduit. It can
find an open in unshielded circuits like Romex or wires run through PVC conduit.
Use a separate or earth ground as shown under “Tracing the Path of a Hidden Wire (Live
Circuit)” when tracing open circuits (see illustration at end of section).
1. Attach both alligator clips to the transmitter adapter. Attach one clip from the transmit-
ter adapter plug to a separate or earth ground. If a separate or earth ground is not
easily available, a soft ground to a metal chair or table may be used, but sensitivity
and range are reduced. You can check to see if you have a separate or earth ground by
checking the ground wire for signal. The receiver will not detect a strong signal on the
ground wire if properly grounded.
2. Plug the transmitter into the transmitter adapter plug. Attach the other clip from the
transmitter adapter plug to the conductor of the wire being traced. Turn the transmitter
ON. The transmitter will indicate OPEN LINE MODE.
3. Taking into consideration the path of the circuit being tested, hold the receiver away
from the wire at the distance you will keep it initially while tracing, and then set to
HIGH RANGE. If you are within signal range, all five LEDs will flash and automatically
set the signal level to three LEDs.
4. Find the open wire by moving the receiver slowly along the circuit at the same
distance, while watching for a decrease in signal strength as indicated by fewer LEDs
lighting. The open is at the point that the signal decreases just before the signal is lost
completely. To more specifically pinpoint the location, set the receiver to LOW RANGE
and scan the area.
Note:
The 2011 works best on opens when held in your hand because your hand and
body act as a ground plane reference. This improves the sensitivity of the receiver.
Without this ground plane reference, the signal range will be reduced.
