Functional Test Versus Performance Verification
Functional Test Versus Performance Verification
Functional tests use a minimum set of test equipment to check a much smaller
range of parameters (and a limited number of data points for each parameter)
than do performance verification tests. Functional tests use limits that are
wider than the published specifications; measurement uncertainty analysis is
not available for functional tests.
Performance verification tests span a wide range of instrument parameters and
provide the highest level of confidence that the instrument conforms to
published specifications. These tests can be time consuming and require
extensive test equipment.
If a functional test does not pass, you must run performance verification tests to determine
whether a problem exists.
