3 Using the vLoc3 RTK-Pro
When applying a clamp close to a grounding point where multiple grounds or a grounding bus exists, ensure that you place the
clamp around the target line and not to the ground bus/other grounds. This will help focus the applied signal on the target line.
Clamp Extension Rod
A useful accessory to the clamp is the extension rod:
The extension rod is fitted with a 10mm threaded male stud. This male thread screws into the handle of the signal clamp to
extend the distance of the clamp. This helps areas with difficult access, such as in manholes or trenches.
(not to be used on uninsulated overhead power cables).
The extension rod is fitted with a female thread in the handle. The female thread allows the rods to be joined together to extend
the range. To access this thread, slide the yellow handle off the rod.
To operate the clamp jaws when attached to the rod, gently pull on the clamp cord, which will open the jaws. Release cable to
close them.
WARNING
Always follow the appropriate safety requirements mandated by safety legislation, safety practice,
and your company’s safety procedures when applying a clamp (coupler) to a cable.
BEWARE that when placing a clamp around cables carrying high current, the clamp may vibrate, jump
or close violently due to induced current from the target cable.
High voltages can be induced back onto the clamp and be present at the clamp’s plug in some
situations. Safety practices should be followed at all times when clamping around live target lines!
Always ensure the clamp is connected to the transmitter before clamping around a line.
