2. On the Property panel, in the Limit Definition panel, set Upper Limits and Lower Limits to 100%.
3. For Calculation Method, select Statistical Limits from Table or Range Percentage from Table.
MTS MP and MTS RPC
The Statistic method in MTS RPC is the same as the Statistical Percentage method in MTS MP. The
Manual method in MTS RPC is the same as the Statistical Limits from Table method in MTS MPE.
Note:
MTS RPC does not define a Min value, so the range is not clearly defined.
RPC Full Scale method (using Min=-Max)
LowerLimit = Statistic – LowerPercentage * Range / 2
UpperLimit = Statistic + UpperPercentage * Range / 2
RPC Full Scale method (using Min=0.0)
LowerLimit = Statistic – LowerPercentage * Range
UpperLimit = Statistic + UpperPercentage * Range
