Title:
MEASURING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/246405
Kind Code:
A1
Abstract:
Provided is a measuring device which facilitates equipment calibration. A measuring device 1 for measuring noise contained in equipment having a prescribed resistance value is provided with a first voltage-dividing circuit 112 connected to a direct-current power source 111, a second voltage-dividing circuit 113 connected in parallel with the first voltage-dividing circuit 112, and a measuring unit 11 which measures a first voltage-divided voltage output from the first voltage-dividing circuit 112, and a second voltage-divided voltage output from the second voltage-dividing circuit 113, a calculating unit 12 which calculates the difference between the measured first voltage-divided voltage and second voltage-divided voltage, and an output unit 13 which outputs the calculated result, wherein: the first voltage-dividing circuit 112 outputs the first voltage-divided voltage from the equipment and a first resistor 130, connected in series; and the second voltage-dividing circuit 113 outputs the second voltage-divided voltage from a second resistor having the same resistance value as the resistance value of the equipment, and a third resistor 150 having the same resistance value as the resistance value of the first resistor 130, which are connected in series.
