Error Term Data
The error term descriptions in this section include the following information:
- a table of error terms
- description and significance of each error term
- measurements affected by each error term
- typical cause of failure for each error term
The same description applies to both the forward (F) and reverse (R) terms.
If Error Terms Seem Worse than Expected
To verify that the system still conforms to specifications, perform a system
verification. Refer to “System Verification” on page 2-20.
Data are listed here as a convenience only. Detailed instrument
