PURPOSE:To accurately measure the temperature of each resistor element in a resistor array by a simple construction, by bringing an array of thermistors into thermal contact with the resistors, respectively, and measuring the temperature of each of the resistors based on an output from each of the thermistors. CONSTITUTION:A thermistor array 6 is fitted to a stage for ensuring proper contact of each thermistor 11 with each resistor element 2 in a resistor array 1. Outputs from the thermistors 11 are inputted to a switch group for switchably leading the outputs to a resistance measuring instrument provided with a comparator. The temperature of each of the resistor elements 2 can be measured simply by bringing the thermistors 11 in the array 6 into thermal contact with the resistor elements 2, respectively, and sequentially switching the outputs of the thermistors 11 to measure the temperature. When the number of the thermistors 11 provided is equal to the number of the resistor elements in the resistor array 1, it is unnecessary to move the stage. |
