Error Messages, Diagnostic
Functions, and
Troubleshooting
Consult this chapter when diagnosing problems with your 2414 RI detector.
Because the detector measures bulk properties of the system, the source of an
apparent detector problem can lie with the chromatography itself or the other
instruments in your system.
If you suspect that a problem is a general chromatography problem, refer to
“Chromatography troubleshooting” on page 105 .
7.1 Error messages
The detector can display two types of error messages:
• Messages requiring you to cycle power and then contact Waters Technical
Service if the error persists (see “Accessing the diagnostic functions” on
page 98 ). Most errors in this category are encountered on startup.
• Messages requiring you to perform a specific corrective action. These can
appear at startup and during operation.
7.1.1 Startup error messages
Startup diagnostic routines run automatically when you power-on the detector. These
diagnostic routines verify the proper operation of the detector electronics. If one or
more of the startup diagnostic tests fail, the detector beeps and displays an error
message.
Note:
To help avoid errors at startup, confirm that the flow cell contains fresh
degassed solvent and no air bubbles.
