This chapter describes the functional tests and provides information on
how to perform them.

What Are the Functional Tests?

Functional tests are tests of various instrument parameters that give a
high degree of confidence that the instrument is operating correctly.
They are recommended as a check of instrument operation for incoming
inspection or after a repair. Measurement uncertainty analysis is not
available for functional tests, and the instrument is checked against
limits that are wider than the published specifications. The functional
tests are designed to test an instrument operating within the
temperature range defined by the instrument specifications using a
minimum set of test equipment. If a test does not pass, performance
tests must be run to confirm a problem exists.
Functional Test Versus Performance Verification
Performance verification tests check a wide range of instrument
parameters and provide the highest level of confidence that the
instrument is operating satisfactorily. They are used to verify that the
instrument conforms to published specifications. They are time
consuming and require extensive test equipment. The functional tests
check a much smaller range of parameters and a limited number of
data points for each parameter. They require only limited test
equipment.
