Signal Type
The 250R can detect two types of signals:
• Active signals are placed on a target line with a transmitter and detected by the receiver. As an option,
an active signal from a beacon (sonde) can also be detected by the receiver.
• Passive signals reside on the target line and are read by receiver.
Active
There are three ways to place active signals on a target line with a transmitter:
• Direct connection (preferred method) requires a connection to be made directly onto target line.
• Induction requires placing an optional induction clamp around target line.
• Broadcast method uses a built-in antenna to broadcast a signal onto lines near the transmitter.
Beacon (Sonde)
Beacon (sonde) signals allow metallic and non-metallic pipe tracing.
Passive
Power line signals can be detected passively without a transmitter.
