Abstract

Technologies for analyzing and deactivating an explosive device include electrically connecting an analysis device to a pair of trigger wires of the explosive device, performing a number of electrical measurements, and determining a deactivation action to be performed on the explosive device based on the electrical measurements (e.g., based on the calculated resistance between the trigger wires). In a disclosed embodiment, a primary lead of the analysis device is electrically coupled to a first trigger wire of the explosive device and a pair of secondary leads are each electrically coupled to a second trigger wire of the explosive device. The analysis device measures a voltage between the primary lead and at least one of the secondary leads. The analysis device also measures a current flowing through the secondary leads after a link of trigger wire extending between the leads has been cut or broken. The analysis device determines the deactivation action by determining a resistance of the analysis device based on the measured voltage and current. The deactivation action may include applying shunt to the trigger wires or cutting one or more trigger wires.
