Creating a Degradation Minimum Value Calculation
Tip: Degradation minimum value calculations that come with APM are listed below. See Degradation Minimum Value Calculations Provided.How the Calculator is Used
For assets that support it, the Minimum Value Calculator is available on the asset’s design rate, indicator’s rate, and failure mode’s degradation rate. You can open the calculator by clicking the Calculate button. For example:You can enter values, calculate a minimum degradation value, and view the results of the calculation. Add calculation pages as required to try other formulas and inputs. Finally, mark a calculation as selected and click OK to return the result to the degradation rate. For more information about using the calculator, see Adding Degradation Information to an Asset.Steps to Set up a Minimum Value Calculator
The calculator is available by asset type, and you can assemble its components in the asset type’s Degradation tab. Setting up a Minimum Value Calculator involves these steps:To do this, select the site’s Assets view, Settings tab, and Subtype and General Specifications tab. Select the Design codes node in the tree and click New at the bottom of the table. Here is an example of a design code:
4. On the asset type’s Degradation tab, select Assets of this type support minimum value calculation and click New to assemble the components. For example:Note: The Minimum value box records the minimum degradation value specified by the design code standard. This value is assigned to the asset if the calculator returns a lower value.
