Instructions for Use
To trace a tone
1) Connect an audio frequency tone generator,
such as the Test-Um TG100, to cable to
be traced.
Application Hints
When tracing wires terminated to a terminal
block such as a “66 block”, attaching both
generator leads to the cable or pair tends to
contain the signal within the cable. The tracer
must nearly touch the end of the cable to
detect the signal, which is helpful when the
wires are close together, as when terminated.
When tracing along cable runs and to
maximize radiated signal, connect one lead
of the generator to the wire or cable, and the
other end to ground (case of an electrical box,
electrical conduit, metallic water pipe or ground
rod). If no ground is available, do not connect
the other lead to anything — let it dangle
as near to the earth as possible. Connect the
generator to the ungrounded shield of a coax
cable. The shield will do it’s job, if connected
to the center lead.
2) Press the recessed black button to turn on the
TT100. The power is on only as long as the
button is being pressed. The battery low LED
flashing on during turn on and turn off is normal.
3) Adjust volume to a comfortable level. If the
signal is very loud when near the cable, the
volume may need to be reduced to keep from
overloading the TT100. When overloaded, small
increases or decreases in the signal at the tip
cannot be heard.
4) Hold tip of TT100 near cables to be identified.
The signal will be loudest on the wire or cable
with the generator attached to it. Separating
the wires or cables may help in identifying the
correct one.
To Use Headset
1) Insert 2.5 mm headset plug into end of TT100
by the lanyard loop, be sure to fully seat the
plug into the jack. The speaker is automatically
disconnected.
2) Remove old battery and disconnect from
battery leads.
3) Snap battery leads onto new battery (9 volt,
alkaline). Place battery in case.
2) Proceed as in the preceding section.
4) Replace battery door and screw. Do not over
tighten.
