5.7.1 Numbered Algorithm The Numbered algorithm is used to find the maximum peak or valley within a specified scope range and that meet a specified sensitivity.
5.7.1.2 Index The Index default value is 1. An Index = 1 means that the result is measured at the first incident (looking at the data from left to right) on the curve where the Sensitivity qualification is met. If the Index value is 2, the data stream on the curve is evaluated for sensitivity to determine which peaks and valleys are qualified, and then it looks for the second incident to report the maximum peak or maximum valley.
Selecting above the curve will report using the peaks data, while selecting below the curve will report the valleys data.
The numbered algorithm may be used for load or distance.
5.7.1.1 Sensitivity Sensitivity is a percent value. It is the percent that qualifies a peak or a valley based on an equal percentage rise and fall. For example a sen- sitivity of 25 would look at all data within a defined scope region where the data for a rise and fall is at least 25% of greater. When the portion of the curve qualified against the sensitivity, it is highlited in blue. If a rise on the curve for load was 25% (an increase in load from the start of the rise to the end of the rise (peak), and the fall on the curve was less than 25%, this portion of the curve would not qualify, therefore, the segment on the curve is not a valid peak and valley. This portion of the curve would not highlight in blue.
You may use a negative Index number (e.g. -1). When a negative index is used, the data is evaluated from right to left.
There was a rise and fall of 5N or greater. The highlited peaks are qualified as having a rise and fall of 5N or more.
There are eleven (11) qualified peaks.
