Abstract: A measuring device facilitates equipment calibration. A measuring device for measuring noise contained in equipment having a prescribed resistance value is provided with a first voltage-dividing circuit connected to a direct-current power source, a second voltage-dividing circuit connected in parallel with the first voltage-dividing circuit , and a measuring unit which measures a first voltage-divided voltage output from the first voltage-dividing circuit, and a second voltage-divided voltage output from the second voltage-dividing circuit, a calculating unit which calculates the difference between the measured first voltage-divided voltage and second voltage-divided voltage, and an output unit which outputs the calculated result, wherein: the first voltage-dividing circuit outputs the first voltage-divided voltage from the equipment and a first resistor, connected in series.
