MEASURING DEVICE

PROBLEM TO BE SOLVED: To provide a measuring device which evaluates the validity of a measured value when current/voltage/power are measured by a plurality of sampling data for every predetermined segment. SOLUTION: In the measuring device 1, an arithmetic means 33 calculates a measured value for every measurement segment, based on sampling data acquired by A/D converting input data with a predetermined sampling period, a detecting means 34 detects whether the input data when the sampling data is acquired by A/D conversion, is a value within the A/D conversion range, and a data outputting means 36 for outputting the result detected by the detecting means 34 and measured value calculated by the arithmetic means 33 regarding any measurement segment, is provided.
