VM-480B Transmitter Signal Clamp
Signal Clamps provide a precise way to apply a locate signal. They are generally used when it is not possible or convenient to access the conductor to connect or when it is not safe to connect because the target cable carries electricity.
Signal Clamps are specialized inductive devices, sometimes known as a toroid or coupler. All clamps are optimized to work at specific frequencies. In most cases, clamps are designed to be used at frequencies generally between 8 kHz and 85 kHz.
