(1) the standard state Wave data that prestores;
(2) the upper and lower domain of walker of the longitudinal axis is set, has formed dynamic envelope diagram;
(3) with dynamic data to be measured with the standard state phase of wave with time base and amplitude and the comparison of standard state Wave data; If dynamic data to be measured is not in the scope of envelope diagram; Then think and treat that at present examining system is in ERST; From this moment to reaching within the normal range dynamic data to be measured in the corresponding moment of storage automatically, within the data arrives normal range or the time arrive template finish time, simultaneity factor will provide corresponding prompt.
Standard state Wave data and dynamic data to be measured that described storage Control Software prestores carry out the contrast in one or more cycles.
That described standard state Wave data is meant is stable, the transverse axis and the ordinate of orthogonal axes of tested waveform under the normal condition.
The described standard state Wave data that prestores comprises the steps:
Configure the scalar of the transverse axis and the longitudinal axis;
The user gets into the standard state that prestores through clicking " prestoring " button, and " prestoring " button connects the CPU processing module;
The storage Control Software is set up corresponding data file successively in internal memory; The Data Filename number order increases; The transverse axis of the current setting of data file stored record and the coordinate amount of the longitudinal axis, the data that wherein prestore are that the coordinate amount with transverse axis is to peek in the time interval.
The present invention stores abnormal data automatically and points out the user according to tested Wave data upper and lower limit condition dynamically, is convenient to find the dynamic abnormal of signal.Also be beneficial to simultaneously the analysis and the processing to abnormal data in later stage.
