Locating and tracing of cables in walls

• Switch on the instrument via the switch on/off and sensitivity potentiometer

(5)

• Set selection switch between Fuse and Cable to "Cable” (4).

• Plug the transmitter into socket of respective current circuit.

• Set sensitivity via sensitivity potentiometer (5) to the highest sensitivity.

• Now approach the plugged-in transmitter with the sensor (1) and try to re-

ceive a signal. A signal received is indicated by the symbol "H" (6) on the dis-

play as well as the blinking of the LED (2). At the same time an acoustic si-

gnal is audible depending on the intensity of the signal.

• Now try to locate the signal by circling movements at the wall (see drawing

below). If a signal is received, reduce the sensitivity level via the potentiome-

ter (5) until the minimum reception of the signal is achieved. If the signal de-

creases when tracing along the wall, you have either increased the distance

from the actual cable installation or the cable has been installed deeper into

the wall at this point. If required, reset the sensitivity level via the potentio-

meter (5) in order to retrieve the signal.

Depending on local conditions, the tracing depth amounts to approx. 0...40 cm.
