cable and it is up to the operator to select the frequency best
suited to his/her particular conditions.
The red Transmit LED will blink when the unit is in HI or LO mode
and a good tracking signal circuit has been formed. The brighter
the LED blinks, the better the circuit conduction and therefore the
better the tracking signal is working. A dim blinking LED indicates
a poor circuit and consequently, tracking the wire/cable will be
difficult.
In Induction Mode, the Transmit LED will not come on. The
Induction LED will, indicating that you are transmitting an induction
frequency for use as described below.
Experiment with which setting works best for the job you are
doing. NOTE - THE TRANSMITTER AND RECEIVER MUST
BOTH BE ON THE SAME FREQUENCY SETTING (Hi or Lo) TO
WORK PROPERLY.
Setting up the Transmitter: Inductive Antenna
–
The Pro871C
transmitter has an antenna used for transmitting a tracing signal
without connecting to the cable. This is called induction. This
feature is handy when the user has no access to the physical
metal of the cable or does not wish to disconnect the cable from
service. To use the Pro871C inductive antenna (built into the
case), the user merely needs to select “induction” on the
transmitter control panel after turning it on. The Pro871C wand
also needs to b
e put in the “induction” mode. After the wand has
been put into “induction” mode, track the wire as normal, following
the transmitted beeping signal. As a note, the transmitted signal
will interfere with your locate up to 20 feet from the transmitter as
the signal emits in all directions. Start the locate at least 20 feet
from the transmitter.
Setting up the Transmitter: Inductive Clamp -
To use the IC4
clamp, plug the clamp into the clamp receptacle on the Pro871T
transmitter and turn the unit on, us
ing the “Induction” setting on
both the transmitter and receiver. Clamp the IC4 around the cable
to be traced. For best performance, orient the clamp so that the
side with the wired handle is closest to the cable. You can also
increase the effectiveness of the clamp by wrapping the target
