A measuring device (1) has, e.g., a voice input portion (27) for
a measurer to input an arbitrary comment at a time of measurement, and it allows
a voice recognition portion (28) to recognize the measurer's comment inputted
by the voice input portion (27) and also allows a recognition result to
be stored in a comment storing portion (43) in correlation with information
on date and time, thereby storing conditions or the like of the measurer at the
time of measurement, together with the measurement data.
