Zusammenfassung:	A test circuit for determining when one of a number of source voltages deviates from its set point. Each source voltage has coordinated comparison circuit which compares the voltage with a preset value, and which has a limited range of output voltage. Each comparison circuit has its output connected to a switching circuit. The output of each switching circuit is connected to a short circuit coil of one coupling transformer. The coupling transformer is fed from an auxiliary current source through an auxiliary coil and has as output a pick-up coil connected to an evaluation device.
