Abstract
The analog data to be input into a microprocessor (10) are represented by resistance values. The period of time for discharging a capacitor (16) via a reference resistor (17) and via the resistor (8) to be measured, which is in series with the reference resistor (17) is determined. The reference resistor (17) forms a protection for the microprocessor against interferring currents which can occur in the resistor (18) to be measured. <IMAGE>
