Abstract

A measurement device according to one aspect of the present invention includes a first controller configured to output a control signal and a second controller configured to perform a first control and then to perform a second control based on the control signal output from the first controller. The control signal designates both an input signal and a calibration signal to be converted into a digital input signal and a digital calibration signal, respectively. The input signal is input from an outside of the measurement device. The calibration signal is previously prepared. The first control is for selecting the input signal and converting the selected input signal into the digital input signal. The second control is for selecting the calibration signal and converting the selected calibration signal into the digital calibration signal and for calculating a measured value using the digital input signal converted by the first control and another digital calibration signal converted by a control performed before the first control.
