Abstract
A measuring device and a measuring method for non-destructive testing of an ignitor installed in a subassembly, particularly of a motor vehicle. The device and measuring method generate a measuring current with a predefined value, check-test the predefined value of the measuring current while bypassing the ignitor, apply the check-tested measuring current to the subassembly with the installed ignitor for a predefined time interval, determine the internal resistance of the subassembly with the installed ignitor, and derive a test signal indicating the installation condition based on a comparison with a setpoint value.
