Abstract:
A method for determining a resistance value of a plural number of actuating devices is provided. The method features a step of the application of a test current pulse at each of the plural number of actuating devices. Moreover, the method features the step of the evaluation of a total current of output currents of the plural number of actuating devices engaging on the test current pulses at a measuring resistor, in order to determine the resistance value of the plural number of actuating devices.
