To provide a measurement data recording apparatus recording measurement data satisfying a recording condition over a desired time interval.
When the number of times of outputs from a measurement section of pieces of measurement data satisfying a first recording condition that a measurement value (electric parameter of an input signal) is lower than a lower limit set beforehand, exceeds a first set number of times within a first set interval of time (S30), while the first recording condition is set in the measurement data recording apparatus, the lower limit is changed so as to be a value lower by a first amount of change set beforehand (S31). When the number of times of outputs from the measurement section of pieces of measurement data satisfying a second recording condition that a measurement value exceeds an upper limit set beforehand, exceeds a second set number of times within a second set interval of time (S30), while the second recording condition is set, the upper limit is changed so as to be a value higher by a second amount of change set beforehand (S31).
