IDENTIFY URD CABLE USING ACDM RECEIVER
The ACDM Receiver is a handheld analog receiver that indicates a needle
movement representation of the direction & pulse strength applied to the cable.
1.
Follow the “DC TRANSMITTER SET-UP AND TEST” Procedure
outlined on page 4.
2.
Ensure the power light is on, the blue pulse light is pulsing, and the
green short continuity light is illuminated. If the red open light is on,
turn the unit off, check your connections and try again.
3.
Plug the CT into the ACDM receiver.
4.
Clamp the CT around the cable at the source so the red arrow faces
away from the transmitter on the cable. (Pointing towards the grounded
end of the cable.)
5.
If the red cable is attached to the center conductor and the black cable
is attached to the ground the needle should deflect in the Green area on
the meter. If not, check your connections on the DCI100 and the make
sure the red arrow on the CT is pointing away from the transmitter.
6.
At the test site location, clamp the CT around each of the cables, so the
red arrow is facing towards the grounded end of the cable.
7.
The same deflection in the green area means you’ve identified the same
cable that the DCI100 is attached to. Any other deflection means you
are not on the correct cable.
8.
After testing is complete remove all equipment and restore cable to its
original condition.
