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.
If a functional test does not pass, you must run performance verification tests
NOTE
to determine whether a problem exists.
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.
