Cable Tests

OHMMETER SET AT R X 100K

Procedure-

1) Submerge cable and splice in a steel barrel of water with both ends out of water.

2) Use an ohmmeter with the scale lever set to R x 100K (R x 100,000).

Short the meter leads together and "zero" the ohmmeter using the meter's adjustment dial.

3) Connect one meter lead to the steel barrel (ground) and the other meter lead to each cable

lead individually. See diagram...

Checking Cable and Splice:

IF THE BARREL IS PLASTIC, ATTACH THIS METER LEAD

TO THE BARE END OF AN ADDITIONAL WIRE WITH

THE OPPOSITE BARE END SUBMERGED IN THE WATER.

STEEL BARREL

4) If the ohmmeter reading drops towards zero (0) ohms on any of the cable leads, pull the

splice up out of the water. If the ohmmeter reading increases towards infinity ( ) the leak

is in the splice.



5) If the leak is not in the splice, pull the cable out of the water slowly until the ohmmeter

reading increases towards infinity ( ). When the ohms value increases, the leak is at that

point in the cable.



6) If the cable or splice is bad, it should be repaired or replaced.
