Signal Clamp Accessory - Tracing An Individual Pipe Or Cable - Amprobe UAT-600 Serie Mode D'emploi

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. The Transmitter will
switch automatically to the Clamp Mode and the display will show the clamp icon
3. Clamp the Signal Clamp around the target line.
4. Press the button repeatedly to select 8 kHz frequency (preferred for most tracing situations) or 33 kHz.
Refer to section 4.1 When to Use 8 kHz vs. 33 kHz Frequency for more information. Frequencies "A-LO"
and "A-Hi" are used for cable sheath ground fault locating and is described later in the manual.
5. Press the " / " buttons to set the output to level one. 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 either 8 kHz or 33 kHz
depending on the Transmitter setup.
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.
