New rate type The rate types available depend on the indicator type’s degradation settings. Rate types are: • Asset design rate: Expected yearly degradation rate of the asset as designed (for example, 0.09 mm / year). • Indicator rate: If the degradation parameters differ from the asset design at a specific measurement location, the parameters are entered on the indicator. The resulting calculation is known as the indicator rate. • Short-term rate: The difference between the previous reading and the current reading. For the first reading, if there is no indicator rate, the start value and date are taken from the asset’s degradation rate. • Long-term rate: The difference between the first reading and the current reading. For the first reading, if there is no indicator rate, the start value and date is taken from the asset’s degradation rate. • Custom rate: You can define up to three custom calculations in the Customization Center and then assign them to indicator types. For example, you might use linear regression to calculate degradation. • Inspector rate: The person performing a risk-based inspection analysis or creating an inspection report can enter a selected rate and apply it to the current indicator reading. This rate is in effect until the next reading is taken. See Also Calculation Custom calculation used to determine degradation. See Also
