Intended Use
The system can be configured to locate pipe and cable or trace non-metallic pipe or conduit.
The 250R receiver is configured to operate in twin peak mode with one active frequency (33 kHz) as well
as radio, 50P or 60P and 50S or 60S.
The 250T transmitter places signals on target lines and is used with 250R units. It is configured to send 33
kHz frequency signals. It places a signal on the line through either direct connection, induction clamping, or
broadcast modes.
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 250 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.
