operating transmitter. A beeping sound should be heard indicating
that the receiver is working properly. A fading or scratchy signal may
indicate a low battery.
There are two receiver wand modes 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.
NOTE – The receiver and transmitter must always be in the same
mode to operate correctly.
The knob on the receiver control panel regulates the volume level of
the receiver for both headphones and external speaker. Additionally,
the signal LED group 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. The feedback of your locate is
given in two manners: audible external speaker and headset. These
options audibly indicate signal strength that is being received by the
Pro881™.
Finding Faults – Breaks or severe wire damage can be found the with
Pro881™. 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
