Method for setting reference voltages in an A/D converter

An analog multiplexer (MUX) connects measuring voltages of different measuring points (M1 to M4) to an analog/digital converter (A/D) which forwards the measured values in digitised form to a process control computer (P). When the multiplexer (MUX) is switched over to a measuring point (M1 to M4), r...

Zusammenfassung:	An analog multiplexer (MUX) connects measuring voltages of different measuring points (M1 to M4) to an analog/digital converter (A/D) which forwards the measured values in digitised form to a process control computer (P). When the multiplexer (MUX) is switched over to a measuring point (M1 to M4), reference voltages are selected in the process control computer (P) which are fed via a digital/analog converter (D/A) to the A/D converter as an input voltage range for the respective measuring point (M1 to M4).
