Measuring Length to Short Faults (cables with 3 or more conductor wires)
While measuring a cable with 3 or more conductors, to accurately
identify which wires are shorted and the distance to the short
location, multiple measurements of different wire combinations
should be measured. For example, if measuring NM 14/2 electrical
cable, the steps for testing are as follows:
1. Set up the tester as outlined in the MEASURING TWO
CONDUCTOR AND OTHER CABLE section on previous page.
2. Connect the HOT and NEUTRAL wires to the red alligator clip,
and the GROUND wire to the black alligator clip. If "SHORT" is
displayed, at least one of the HOT and NEUTRAL wires is shorted
with GROUND. If "SHORT" is not displayed, there is no short
between HOT or NEUTRAL and GROUND.
3. Connect the HOT and GROUND wires to the red alligator clip, and
the NEUTRAL wire to the black alligator clip. Similarly, if "SHORT"
is displayed, at least one of the HOT and GROUND wires is shorted
with NEUTAL. If "SHORT" is not displayed, there is no short
between HOT or GROUND and NEUTRAL.
4. Connect the NEUTRAL and GROUND wires to the red alligator clip,
and the HOT wire to the black alligator clip. Similarly, if "SHORT"
is displayed, at least one of the NEUTRAL and GROUND wires is
shorted with HOT. If "SHORT" is not displayed, there is no short
between NEUTRAL or GROUND and HOT.
