Understanding
the Confidence Tests
At power-up, the Autosampler CE runs a set of
13 confidence tests to check its internal electron-
ics and memory, display, keypad, motors, and
sensors. If a system that is critical to continued
operation fails, the confidence tests stop and the
Autosampler CE shuts down with an error
message on the display, unless the display itself
fails the test. If the display fails, it may remain
blank or display random letters and symbols. If
the Autosampler CE test error is noncritical to
the remaining tests, the confidence tests finish,
but the last error message remains on the display
and the Autosampler CE does not go into an
operable mode.
If a confidence test error message is displayed,
see the “Error Messages” section in Chapter 6
to determine the problem. If the display is not
functional, you can use the confidence test
Ready light inside the instrument (viewed
through the vents on the back of the instrument)
to determine which test(s) detected an error (see
“Using the Confidence Test Ready Light” on
page 6–3).
