Section 5 Electrical Troubleshooting
and Diagnostics
5.1 5800 Diagnostics The sampler has built-in diagnostics routines that trained
service technicians use to confirm that all sampler subsystems
are working correctly or to locate faults. Many of the diagnostic
routines also can be run in the field.
In many cases the sampler will determine if the test passes or
fails.
• If a test passes, the sampler displays a message showing
the test passed and emits a short beep.
• If a test fails, the sampler displays a message with some
detail about the failure. The unit will emit a wavering
tone for five seconds.
In a few cases, the service technician must determine if the test
passed or failed based on a sampler function that must be
observed.
The sampler automatically reverts to the SELECT DIAG menu
after displaying the test results or when the test is complete or
expired.
