Self-Test Procedures
Power-On Self-Test
Each time the instrument is powered on, a small set of self-tests are performed.
These tests check that the minimum set of logic and measurement hardware are
functioning properly. Any plug-in modules installed are verified for two-way
communication with the main controller.
Complete Self-Test
Hold down any front panel key for 5 seconds while turning on the power to
perform a complete self-test. The instrument beeps when the test starts. If all
self-tests pass the display shows PASS for five seconds and the instrument
returns to the last measurement function.
Plug-in Module Self-Test
No user self-test exists for the plug-in modules. The plug-in modules perform
their own self-test when power is applied. Additionally, the mainframe checks
two-way communication with all plug-in modules at power on.
Each plug-in module also performs error checking at regular intervals during
operation and any errors detected are reported via the status system to the main
controller.
