Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a measuring device capable of controlling the switching of input ranges in a short time. SOLUTION: A measuring device 1 provided with both an input range switching device 2 to convert the voltage of a signal to be measured SM at a predetermined conversion ratio according to a switching-controlled input range and a range switching control circuit 9 to perform switching control on the input range switching device 2 into an input range according to the voltage value of the signal to be measured SM is provided with a peak voltage detecting circuit 4 to detect the peak voltage VP of the signal to be measured SM, and the range switching control circuit 2 executes first processing to determine an input range capable of allowing the input of the detected peak voltage VP and performs switching control on the input range switching device 2 into the determined input range.
