3M™ Dynatel™ Advanced Modular System 965AMS Measurement Functions

RFL>Wet Pulp

Use this function to find the approximate distance to a resistance fault when both wires in a pair are faulted at the same place and a separate good pair or a single common conductor is not available.

RED Wire With Lower Resistance Value
GRN	Common/Ground

BLK Wire With Higher Resistance Value

1.The resistance faults must be common to the reference (Green) conductor. Use the ohmmeter function to measure the resistance on each side of the pair to the reference conductor.

2.The lower value fault should be connected to the Red test lead.

3.The higher value fault should be connected to the Black test lead.

4.The Green test lead should be connected to the reference conductor, usually the shield or ground.
