o If the CONT indicator [8] does not light, one or both of the
wires are broken, or the wrong wires were connected or short
circuited.
Caution: Make sure the pair of wires under test is not in contact
with any other electrified or earthed object, as this may cause an
incorrect result.
4.2 Cable Detection / Test
Use both the tone generator and the cable tracker to verify where a
cable is going, if it is interrupted or not and where the interruption is
located.
1. Set the tone generator's mode switch [9] to TONE.
The TONE indicator [8] starts flashing.
2. At one end of the cable / wires to be tested, connect the red clip
to any wire or one specific wire you want to test. Connect the
black clip to the ground wire or, if you cannot find it, one of the
other wires.
3. Use the volume control [2] on the side of the cable tracker to
control the volume.
4. Use the probe tip [1] of the cable tracker as follows:
o If you do not know where the cable is going or if there are
several similar cables, you can detect the correct one with the
probe. Hold the probe to the suspected wire and press the
trace button. The signal is the loudest at the correct wire.
o If you do know where the cable is going, the probe allows you
to verify immediately at the other end whether or not the
cable is interrupted. Hold the probe to the end of the wire and
press the trace button. If no signal is obtained, the test wire
is probably interrupted.
o Press and hold the trace button [3] and follow the cable to
where the signal stops: the signal wire is interrupted at that
point.
Remarks:
• The best test results are obtained when the black clip is connected
to a separate ground wire.
• The probe is very sensitive: as it gets nearer the signal wire, the
tone gets louder.
• Electric fields may interfere with the detection of the signal wire.
The tone generator can be used to determine the polarity of a phone
line, and the status of a working line.
1. Set the tone generator's mode switch [9] to OFF.
2. Insert the phone line connector [7] in the phone socket and
connect the red and black connectors [6] to the wires to be
connected. The CONT indicator [8] lights.
o Green means th e polarity is correct (black is "+" (tip) and red
is "–" (ring)).
o Red means the polarity is inversed (black is "–" (ring) and red
is "+" (tip)).
o If the LED does not light up, either the connections are not
established correctly or the socket is not connected.
3. To test the status of a telephone line, first connect the red
connector to the "–" (ring) side and the black connector to the
"+" (tip) side. The CONT indicator [8] lights.
o Green indicates a clear line.
o Flickering yellow means there is an incoming phone call (ring
signal).
Note: In this case, set the mode switch to CONT to terminate
the call on the line.
o If the LED does not light up, the line is busy.
4.4 Selecting the Tone
Select the tone you want to hear (single or dual tone) with the audio
signal switch at the inside of the tone generator.
1. Open the battery compartment and remove the battery.
2. Unscrew the screw in the battery compartment and the four
screws in the back cover.
3. Carefully remove the back cover and lift the PCB.
The audio signal switch is located at the left side of the PCB
(component side up, battery connectors at the bottom).
4. Set the switch in the desired position.
5. Replace the PCB carefully and put the cover back.
Caution: Make sure that no wires are crimped and that the
mode switch is in position. The indicator LEDs should fit easily
through the holes. Do not force.
2. Verbind aan het ene uiteinde van de te testen kabel de rode
klem met eender welke draadkern, of één specifieke kern die u
wil testen. Zet de zwarte klem op de aarding of, als deze niet
voorhanden is, op een van de andere draadkernen.
3. De geluidssterkte is regelbaar met de volumeregeling [2].
4. Gebruik het testpunt [1] als volgt:
o Als u niet weet waar een kabel naartoe gaat of er zijn
verschillende gelijke kabels, kunt u de juiste kabel vinden met
de sonde. Houd de sonde tegen de vermoedelijke kabel en
druk op de zoekknop. Het signaal klinkt het luidst ter hoogte
van de juiste kabel.
o Als u wel weet waar een kabel uitkomt, kunt u aan het andere
eind meteen testen of de kabel niet onderbroken is. Houd de
sonde tegen het uiteinde van de kabel en druk op de
zoekknop. Als er geen signaal is, is de geteste draadkern
waarschijnlijk ergens onderbroken.
o Volg de kabe l terwijl u de zoekknop [3] ingedrukt houdt tot
waar het signaal ophoudt; de draadkern is op dat punt
onderbroken.
Opmerkingen:
• U zult de beste testresultaten krijgen wanneer de zwarte klem
met een afzonderlijke aardekabel is verbonden.
• De sonde is zeer gevoelig: naarmate ze dichter bij de kabel komt,
wordt de toon luider.
• Elektrische velden kunnen de ontvangst van de signaalkabel
storen.
4.3 Telefoonaansluitingtest (RJ12)
De toongenerator kan worden gebruikt om de polariteit van een
telefoonlijn te bepalen, en de status van een actieve lijn.
1. Zet de modusschakelaar van de toongenerator [9] op OFF.
2. Steek de telefoonconnector [7] in de contactdoos van de
telefoon en verbind de rode en zwarte klemmen [6] met de
draden die moeten aangesloten worden. De signaalled CONT [8]
licht op.
o Groen betekent dat de polariteit juist is (zwart is "+" (tip) en
rood is "–" (ring)).
o Rood betekent dat de polariteit omgekeerd is (zwart is "–"
