The current measurement module CMM_III can be used to measure, evaluate and check current consumption of a dynamic DC load, typically an automotive electronic control unit. It can measure currents from 1µA to 100ADC (190A range) with automatic range selection within a few microseconds. The current range from 1µA to 190A is split into 7 Ranges, i.e., seven decades.
