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 a 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 suits you best. In
general, the closer you are to the cable, the louder the signal should be
except for directly over the cable in 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.
Additionally, the feedback of your locate is given in 3 manners: audible
external speaker, headset, or signal meter. Any of these three options
indicate signal strength that is being received by the Pro900™.
