Locating And Tracing Of Cables In Walls - Beha-Amprobe SF100 Mode D'emploi

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 receive a signal. A signal received is indicated by the symbol
"H" (6) on the display as well as the blinking of the LED (2). At the
same time an acoustic signal is audible depending on the intensi-
ty 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 potentiometer (5) until the minimum reception of the
signal is achieved. If the signal decreases 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.
