Abstract
A converter circuit includes a current interface with a control input, with a current signal output and a current output. The converter circuit includes a micro-processor with a measuring signal input for the digital measuring signal, with a current signal input connected to the current signal output of the current interface, and with a control output connected to the control input of the current interface. The current interface lets the signal current flow through the current output and simultaneously adjust both the amperage to a stationary amperage level corresponding to a control value currently applied to the control input, and to output a sequence of current values at the current signal output. The micro-processor is designed to generate a measuring value sequence on the basis of the digital measuring signal and use it as the basis from which to generate a control value sequence and issue it at the control output as well as to monitor and/or check the current interface using the control value sequence and the current value sequence.
