Patent ID: 8442662

Claim:
A measurement parameter input control method of changing a plurality of measurement parameters of a target device for which the plurality of measurement parameters necessary for performing a measuring process of measuring an electrical signal are set, comprising: a parameter information acquiring step of acquiring measurement parameter information including the measurement parameters from the target device; a parameter information display step of displaying and controlling the acquired measurement parameter information on a display screen; a parameter information selecting step of selecting one measurement parameter from the measurement parameter information displayed on the display screen; a soft key control step of displaying and controlling one parameter setting soft key of a plurality of parameter setting soft keys prepared in advance for changing the measurement parameters on the display screen; a display switching key display step of displaying a display switching key for switching and displaying the plurality of parameter setting soft keys on the display screen; a parameter setting soft key selecting step of displaying the parameter setting soft key other than the displayed parameter setting soft key on the display screen instead of the displayed parameter setting soft key when the display switching key is pressed; and a parameter rewriting step of rewriting the measurement parameter changed by using the previously-selected parameter setting soft key to the target device, wherein the soft key control step includes an upper and lower limit display step of displaying and controlling an upper and lower limit display area for displaying upper and lower limits of the measurement parameters in the vicinity of a parameter display area in the plurality of parameter setting soft keys prepared in advance.
