  • Multimeter with automatic function-setting
    Patent number: 5557197
    Abstract: A multimeter with automatic measurement function setting and automatic recognition of measurement range includes circuitry having a high input resistance for carrying out the recognition of the type of electrical parameter to be measured. When the parameter being measured is recognized as an impedance, however, a low input resistance is automatically switched on, whereupon the magnitude of the impedance is measured at low input resistance and then is displayed, and if the range of measurement changes, the measurement procedure is repeated from the beginning.
