Turn the Pro700 transmitter on. Adjust the power output knob and
increase the power until a reading between 4 and 8 is achieved. If
you cannot achieve a reading of 4, turn the unit off and retry
your grounding operation above. A good ground is crucial for
optimum operation. Soil conditions can also affect this and you
may wish to moisten the grounding area. Also, re-check batteries
for proper connection and operation.
Do not overpower the unit by turning it up past 10 on the meter.
You won't hurt the unit but you will waste battery power for no
additional performance.
Tracing Wire
After the Pro700 transmitter has been properly connected and
verified to have a good ground and power, turn on the Pro700
receiver by turning the volume knob on the front of the receiver.
Place the receiver near the operating Pro700 transmitter. A
beeping sound should be heard indicating that the receiver is
working properly. A high pitched tone could indicate that you are
too close to the receiver or your batteries are low. A fading signal
indicates low battery.
The volume control on the front of the receiver regulates the
loudness of the receiver, both headphones and external speaker.
Additionally, the analog meter on the front of the receiver will
indicate the reception power level visually. After connecting and
turning on the transmitter and turning on the receiver, point the
receiver toward the ground and listen for the beeping signal. The
closer you are to the cable, the louder the signal should be except
for directly over the cable. Directly over the cable, the Pro700
works on the NULL principle. This means that the signal nulls or
stops when the receiver is directly over the cable. If you are a little
to the left or right, the signal will be loud but directly pointing the
receiver at the cable produces virtually no signal. In this way, the
user will know the exact location of the wire or cable being traced.
Finding Faults
Breaks or severe wire damage can be found with the Pro700. 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 break. A nick or damage will cause the
