INSULATION BREAKDOWN/LEAKAGE TEST (CONT)

WARNING

Make sure that cable test stub is properly grounded. Death or serious injury could result

from electrical shock when equipment is in operation.

Extend free end of bare copper wire (8) to ground clamp (9), and secure it properly.

WARNING

Make sure the AN/GSM-6 is properly grounded. Death or serious injury could result

from electrical shock when equipment is in operation.

5. Connect AN/GSM-6 ground cable (10) to ground clamp (9).

6. Connect cable to be tested (11) to connector cap (12) of test cable stub.

7. Mate caps (13).

Twin coaxial cable assembly under test must be capped at the other end. Death or

serious injury to personnel could result from electrical shock.

Twin coaxial adapter cable must not be connected at the other end.

8. Cap twin coaxial cable assembly (14).

9. Perform Starting Procedures on the AN/GSM-6 as outlined in TM 11-6625-273-12.

10. Repeat procedures on page 3-37.

RESISTANCE CHECK

All 1320-foot (1/4-mile) lengths of repaired cable assemblies shall undergo a resistance check. Use

resistance bridge ZM-4B/U. Follow instructions given in TM 11-2019. The following data applies:

Dc resistance of center conductor in each coaxial cable shall not exceed 22 ohms.

Dc resistance of shield in each coaxial cable shall not exceed 7.5 ohms.

Any cable having a higher resistance shall be considered defective. Further action on these defective

cables shall be determined by your supervisor.

Even if a cable passes all of the performance standards, it may not work well in a system. A final

dynamic test is desirable. It may be possible for your supervisor to arrange for a dynamic test using

MUX equipment.
