Claim:
1. A method of testing the status of a wired detonator system which includes a harness and a plurality of detonators connected to the harness, the method including the steps of: 1) from a first defined point in the system propagating a first impulse of energy into the system; 2) at a second defined point in the system recording a first observation of energy reflected by the system in response to the first impulse; 3) conducting a test on the detonator system to determine its integrity and, if the integrity of the system is validated; 4) at the first defined point propagating a second impulse of energy into the system; 5) at the second defined point recording a second observation of energy reflected by the system in response to the second impulse; and 6) comparing the first observation to the second observation to detect a variation in the integrity of the wired detonator system.
