Abstract : This technical report is an evaluation of the engineering methods applied in establishing electrical parameters for key components of the Volcano Mine Dispenser System. as well as the instrumentation used to measure these parameters. One such component in the Volcano system is the magnetic coupling device, which is basically an inductor, or a coil, that plays a particularly important role, of crucial importance in the system's electrical mine/dispenser interface; by setting the self destruct times of the mines, during mine deployment. Electrical parameters had to be established after an investigative team deemed it necessary to have an inductance test added to the assembly procedures of the M87 Volcano canister. This added test will detect shorts in individual coils of the coil and strap assembly which would render all mines in the canister to be duds. It will also detect opens in the individual coils as well as grossly misaligned coils. Both these conditions will cause only the individual mines to dud. The test and measurement techniques used as well as the engineering equations, on which decisions were based, will be reexamined along with reevaluation of the data gathered and instrumentation used. The safety concerns resulting from this issue will also be addressed. (MM)
