Abstract

The voltage is obtd. from the ratio of the resistance to be measured and a standard resistance. The other arm of the voltage divider, with respect to a reference point potential is applied to an amplifier with a high input impedance. Its output signal, whose polarity corresponds to that of the input signal, is applied to a display device. The voltage applied to the amplifier is collected from the tapping of the voltage divider consisting of the measured resistance and the standard resistance. The reference point potential is variable. The reference voltage is collected from a voltage divider supplied with the same constant voltage. Alternatively the reference potential may be generated by a function generator.
