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.
To start the diagnostics from the Main Menu screen:
1. Select the CONFIGURE option and press Enter.
2. Press the Previous arrow until the RUN DIAGNOSTICS
option is displayed. Press Enter.
3. The sampler displays a diagnostic option. Press Enter to
start the test or press the Next or Previous arrows to scroll
through the diagnostic options.
Refer to the sections below for specific information about each
test.
The TEST 'RAM' diagnostic tests the sampler's memory that is
used dynamically by the sampler's processor and holds program
settings and sample event data. This test loads 16-bit words into
memory and reads it back to confirm that the memory is working
correctly.
To run the test:
1. Select the TEST 'RAM' option and press Enter.
2. Wait for the sampler to complete the test.
3. When finished, the sampler displays the test results.
If the sampler reports 'RAM' FAILED contact your authorized Isco
service facility or the Teledyne Isco factory.
