Patent ID: 7365546

Claim:
A measuring device for non-destructive testing of an ignitor installed in a subassembly comprising: means for generating a measuring current with a predefined value; means for check-testing the predefined value of the measuring current while bypassing the igniter; means for applying the check-tested measuring current to the subassembly with the installed ignitor for an adjustable time interval, the adjustable time interval to be at least one of a plurality of values, wherein the means for applying the check-tested measuring current to the subassembly includes a time-controlled circuit element for setting the adjustable time interval; means for determining an internal resistance of the subassembly with the installed ignitor and for deriving a test signal indicating an installation condition based on a comparison of the internal resistance of the subassembly with a setpoint value; and an interface for coupling the measuring device to a computer, wherein the computer controls a test sequence executed by the measuring device.
