3.6 Signal Clamp Accessory – Tracing an Individual Pipe or Cable
In many situations, it is either not possible to gain access to a cable for making an electrical contact or it is not safe to
do so. The Signal Clamp provides an efficient and safe method of applying a locate signal to a cable.
When using the Signal Clamp, it is best if both ends of the target cable are grounded to enable the current to flow.
When applying a clamp close to a grounding point where multiple grounds or a grounding bus exists, ensure that the
clamp is placed around the target line and not to the ground bus/other grounds to reduce the effects of the transmitted
signal also being applied to an unwanted line.
Signal Clamp Accessory – Setting Up the Transmitter
1. Turn the Transmitter on by pressing the power button for two seconds.
2. Connect the black and red test leads of the Signal Clamp to the Transmitter inputs.
3. Clamp the Signal Clamp around the target line.
4. Press Signal button to switch between Hi and Lo signal strength. Lo signal level uses less energy and helps to
preserve batteries. Increase the level if resulting signal strength is poor. Increasing the signal unnecessarily may
result in the signal "bleeding off" onto other services and creating misleading "ghost" signals. It will also drain
more power from the battery.
Signal Clamp Accessory – Locating with the Receiver
1. Turn the Receiver on by pressing the power button for
two seconds.
2. Match the frequency of the Transmitter by pressing the
" " button repeatedly. Select 33 kHz frequency.
3. Follow the steps as described in the Receiver Locating
section 3.1.
4. Use the Left/Right arrow indicators to quickly assess location
of the wire.
5. Optionally measure the depth of the wire. Refer to the Taking
Depth and Current Measurements section 4.3 for details.
