Design and Function
The DCI-50 Cable identifier is used to identify isolated, de-energized URD
cables. The unit features a transmitter with 2 alligator clips and is powered by a
Milwaukee, 18V, rechargeable battery. The unit has 5 LEDs for power, low
battery, pulse operation, short/ open continuity. An optional CT input can be
used when there is excessive neutral current on the cable being tested. The unit
outputs a short duration current pulse that can be detected using one of the
receivers. The receivers available are the STRCV, the AVR receiver, and the
CD1000.
