Locating and Tracing Cables in Walls
See Figure -2-
.
Turn on the receiver using the On/Off switch.
2.
Set the Fuse/Line switch to the Line position.
3.
Plug the ECB transmitter into the socket for AC line to be
traced.
4.
Turn the On/Off switch toward the top of the receiver to
set sensitivity to the highest sensitivity level. Turn toward
the bottom of the receiver to reduce sensitivity.
5.
Place the ECB50A receiver close to the transmitter to
receive a confirmation signal that both ECB50A test
components are active and working. The receiver is
receiving a signal from the transmitter when it displays
the letter “H” on the display and the LED is blinking.
Also an audible signal is present with varied loudness
depending on strength of signal received.
6.
Next, begin locating the signal in the cable to be traced
by circling around the socket. When you receive a
signal, reduce the sensitivity until the minimum signal
is received. If the signal decreases, the receiver is either
moving off the AC cable path or the cable is installed
deeper into the wall. If necessary, adjust the sensitivity
level to increase the signal strength. Depending on local
conditions, the tracing depth amounts to approx. 0 to 40
cm (0 to 5 inches).
