coNNEcTIoN VARIATIoNS
There are several ways to connect the generator to the cable to be traced.
The connection method can greatly change the signal strength detected
by the tone probe or limit coupling to surrounding wires and cables. Too
much signal strength can make it difficult to determine the exact cable or
wire carrying tone.
• Single generator lead: Often just one lead needs to be connected to the
wire or terminal. This is best for tracing along a cable or wire run including
wires behind dry wall. Connect to the shield of a coaxial cable, not the center
lead.
• Both generator leads connected to a cable: Connecting both generator leads
to wires in a cable reduces the radiated signal, especially when connected to
both wires of a twisted pair, due to signal field cancellation. This can be useful
for finding the desired wire or cable in a dense wiring environment such as a
patch panel or a telephone punch-down block. The wires carrying tone must
be very close to the probe tip to be detected. Place the tip in a patch panel
connector or touch a terminal on a block to find the signal.
• Both generator leads, one to ground: With one lead connected to the
wire or cable to trace and the other connected to earth ground, the signal
strength is greatly enhanced. Try a single lead connection first for tracing
along a cable because the ground connection method can yield too much
signal causing poor discrimination between cables or wires.
• RJ plug connection: The RJ plug can be directly connected to a phone jack
and should be the same connection as both generator leads connected to a
pair in a cable, usually line 1 or the center two pins of the jack.
Note: The wire to be traced cannot be at earth or safety ground potential.
The generator signal is shorted out in this instance.
coRREcT pAIR VERIFIcATIoN
When both generator leads are connected to a pair, shorting the two leads
together will cause the tone signal to be shorted out. If the tone probe is on
and nearby, you should hear the tone being lost while the pair is shorted,
verifying the correct pair has been found. This could tell an assistant that the
pair was found and to move on to the next pair.
REpLAcING THE pRoBE TIp
The probe tip can be replaced if it is worn out or damaged with PROBEplus
Probe Replacement Tip Cat. No. VDV999-065
1. Loosen the screw on the back of the probe nearest to the probe tip
using a #1 Phillips screwdriver.
2. pull the old tip out of the probe.
3. push the new tip into the probe. The probe body has a keying slot so
the probe can only be inserted completely in one orientation.
4. Tighten the screw, being careful not to over-tighten. Make sure the
probe tip is firmly held in place by pulling gently on it. If not, tighten
the screw slightly.
BATTERy REpLAcEMENT
1. Remove screw at the speaker end on the rear of the PROBEplus with
a #1 Phillips head screwdriver. Remove battery door.
2. Recycle exhausted battery.
3. Acquire a 9 volt alkaline battery (IEC 6LR61, ANSI/NEDA 1640A).
4. connect battery cable to new battery observing polarity and place
into battery compartment.
5. Replace battery door and screw, taking care not to over-tighten it.
