Intended Use
Intended Use
The system can be configured to locate pipe and cable or trace metallic and non-metallic pipe or conduit.
The 150R receiver is available in peak or null configurations. Unit s con figured to ope rate in the peak mode
will have one active frequency (640Hz, 30kHz or 83kHz) as well as 60S and 60P. Units configured to
operate in null mode will only have one frequency (83kHz).
The 150T transmitter places signals on target lines to be detected by 150R receivers. It is configured to
send 30kHz or 83kHz frequencies. It places a signal on the line through either direct connection, induction
clamping, or broadcast modes.
An optional 150B beacon broadcasts a signal from a metallic pipe, non-metallic pipe or conduit. It is
available in two different frequencies (640Hz, 30kHz). The beacon is attached to a flex rod, placed into a
pipe and tracked with the 150R receiver.
The unit is designed for operation in temperatures typically experienced in earth moving and construction
work environments. Use in any other way is considered contrary to the intended use. The 150 system
should be operated only by persons familiar with its particular characteristics and acquainted with the
relevant safety procedures. The system should be serviced only by Ditch Witch repair centers.
