5: Performance Verification Verification Test Equipment
156
Internal Repairs
If the case was opened (regardless of what else the repair involved), perform all the Performance
Verification and Safety tests:
Run the Performance Verification and Safety tests (see “Test and Inspection Matrix” on page 157
and “Performance Verification Procedures” on page 160).
Verification Test Equipment
Tab le 3 6 lists the equipment needed to perform the Performance Verification and Safety tests, and
provides specifications for commercially available analyzers and simulators. Test equipment is called out
within each test procedure when needed.
