9-3 Other Search Algorithms
9-3-1 Variation Search
This algorithm searches the points where the voltage reaches its minimum and maximum
values. It sets these points as origins to detect the points where the variations begin to be
continuously within the specified range respectively in minimum and maximum voltage
directions. It then determines the period between these detected points as the passage time.
①
Time limit for searching a maximum voltage point from the minimum voltage point: Up to 200ms
②
Duration for which variations are not searched in the minimum voltage direction
③
Duration for which variations are not searched in the maximum voltage direction
④
Duration for which the variation condition continues to be satisfied in the minimum voltage direction
⑤
Duration for which the variation condition continues to be satisfied in the maximum voltage direction
⑥
Variation condition to be continuously satisfied in the minimum voltage direction (mV or less)
⑦
Variation condition to be continuously satisfied in the maximum voltage direction (mV or less)
