%RSD Calculation

Hi, I am using Empower SPM.  I'm having trouble creating the custom field to calculate the %RSD.  The results I am getting from the system does not match the RSD results in the Calibartion Table.S010?.%..%RSD(Response) is this the correct custom field?Thx

  • Hi Gilberto,

    I think that problem might be that you need to specify which peak to calculate the %RSD for as response is a peak level variable. Your custom field that you are creating might also need to be a peak level field as well.

    Try this

    S010?.%..%RSD(Peakname[Response])

    Is this result a number that you need to use in another custom field or is it something that you are reporting? If you are just reporting the number then you might be better off having your report method include this as a summary function for a table of the standards.

    Let me know how you get on.
