• Press Start. The receiver becomes active and will display the signal
level. The controls can also increase/decrease the receiver volume.
• When the receiver is active it can be switched from
PEAK to NULL mode.
TRACING WIRE
After the transmitter has been properly connected and verified to
have a good ground turn on the receiver. The receiver defaults to the
most recently used mode with null antenna reception at every start-up.
Place the receiver near the operating transmitter. A beeping sound
should be heard indicating that the receiver is working properly. A
steady high pitched tone could indicate that you are too close to the
receiver or your batteries are low. A fading or scratchy signal may
indicate low battery.
There are two antenna methods for tracing a path; Null or Peak.
The receiver defaults to Null every time it is turned on. Null means
an absence of signal when pointed directly at the cable in question
and louder to the left and/or right of it a few inches. Peak means the
opposite, that the signal is loudest over the cable. You may select
which mode works best. In general, the closer you are to the cable,
the louder the signal should be except for directly over the cable in
the Null mode. The modes can also be flipped while tracing to give a
better indication of path trace quality.
In Direct Clip-on mode, begin the wire trace by sweeping the area
approximately 5-10 feet from the transmitter. Begin by searching for
the null response. Until the null is acquired, you may receive audible
responses of varying degrees. Follow the signal response until the
signal is lost while marking the path as you trace.
In the Broadcast mode, the signal saturates a circle for at least 20
feet around the transmitter, so you must begin by walking out of that
area, then circling to find the traced wire or pipe.
NOTE - THE RECEIVER AND TRANSMITTER MUST ALWAYS BE
IN THE SAME MODE TO OPERATE CORRECTLY.
The selector arrows on the receiver control panel regulate the
volume level of the receiver, both headphones and external speaker.
Additionally the signal bar on the receiver display will indicate the
signal level visually. After connecting and turning on the transmitter
and the receiver, point the receiver toward the ground in the direction
of the cable and listen for the beeping signal.
FINDING FAULTS
Breaks or severe wire damage can be found with the KING 900.
The setup of the unit is the same as when tracing wire. The difference
comes in the reception. Whereas the traced wire continues to emit a
signal along the path of the cable, a break will cause the signal to
stop at the point of the break. A nick or damage will cause the signal
drop to a lower level but not necessarily end. Either the speaker or
the analog meter on the receiver will indicate this drop.
Be sure the cable or wire you are tracking is grounded - this
completes the “loop” for tracing the current signal. To trace a cable,
it must be grounded, either mechanically or capacitively using the
ground stake. Mechanical means a direct physical ground at one
end. Capacitive grounding generally applies to cable buried directly
in the earth. The signal needs a path to return to the ground stake and
without it, you will not get a good locate. A bad ground is indicated
on the transmitter output signal meter when an OK or mid-range
signal level doesn’t appear even at full power. In many cases,
a direct buried cable fault will provide this grounding and allow for
a cable to be located.
