Error Messages, Diagnostic
Tests, and Troubleshooting
The detector provides both user and service diagnostic tests to troubleshoot
system problems.
5.1 Error messages
5.1.1 Startup error messages
Startup diagnostic tests run automatically when you power-on the detector. They
verify the proper operation of the detector electronics. If one or more of the tests fail,
the detector beeps and displays an error message. For serious errors, it displays the
word “Error” in brackets (<Error>) in place of the run-time absorbance on the
absorbance screen.
Tip:
To reduce the likelihood of errors, be sure the cuvette holder is empty, the flow
cell contains degassed transparent solvent (methanol or water), and the front door
closed securely.
