Zusammenfassung:An electronic thermometer having: a temperature-sensitive probe and one of two optional electronic circuits, each of which has means for changing a basic comparison voltage in steps or increments through a series of stair-stepped voltages toward the amplified small voltage from the thermistor until the stabilized thermistor voltage and the comparison voltage are equal, and indicating the result in degrees. One of these circuits comprises a stairstep generator, and the other a set of resistors of different values.
