earth (e.g. protective conductor, water line) with the black test lead and to a
single wire or a pair of wires with the red test lead. When searching for shield-
ed cables/lines, the red test lead is connected to the shield and the black one
to earth. If there is no shield, two wires (no pair!) are connected to the cable/
line.Ifthescreenisearthed,itmustbedisconnectedonbothsides.Tond
and trace a coax cable, the other end must be open. If this is connected to a
distributor, it cannot be found due to the shielding of the coax cable.
In the case of telecommunication or data cables/lines
with twisted wires, these must not be connected together.
Switch on the device. The selected tone is transmitted. Now select the search
frequency.
If there is a short-circuit, the sound is sent into the cable in a similar way to
interrupted twin wires and all wires are charged with it but only up to a max-
imum of 200 meters.
The cable/line is searched for with the Probe and can be followed contactless
with the Probe from a distance of up to 60 cm away from the cable.
The Probe is switched on by pressing and holding the LOW or HIGH key. To
ndasignalfromagreaterdistanceoraweaksignal,presstheHIGHkey.
In the case of large cable/line bundles at a distributor or in a platform, the
ProbeismovedatoverthebundlewhilepressingtheHIGHbuttonatthe
same time.
Once the cable/line with the strongest signal have been determined, press
theLOWkeytodenethecableyouarelookingforwithmillimeterprecision.
The highest signal level is always above the cable.
Searching Wire Pairs (Twin Wires)
When searching for twin wires and discovering overloads, an ET test lead
is connected to each core of a twin wire. In this case, it must be the twisted
pair. This can be done automatically by plugging into a junction box or by
connecting to the open cable end.
Using the Probe and holding the HIGH button down, the pair is found at
theotherendorateachdistributor.Tondtheexactpairwiththestrongest
signal, the LOW button is pressed. If the pair is twisted over the whole dis-
tance, then the exact pair is found. If, for example, there is a wire break or an
exchange of a single wire (split) on the route, several wires with the search
signal are found at the distributor. This then indicates a cabling error: Now
you have retrace back to narrow down the error.
For open cable ends, the procedure is similar. The wires are fanned out and
