5-2 Error Messages, Diagnostic Tests, and Troubleshooting
Error messages
Startup error messages
Startup diagnostic tests are executed automatically when the detector is
powered on. These tests verify the proper operation of the detector electronics.
If one or more of the internal startup diagnostic tests fails, 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 prevent errors at startup, be sure the cuvette holder is empty, the flow
cell contains degassed transparent solvent (methanol or water), and the front
left panel cover is attached securely.
The tables in this section are organized as follows:
• Messages requiring you to perform corrective action. These include
messages encountered at startup, and during calibration or operation.
• Messages requiring you to recycle power, then contact Waters Technical
Service personnel if the error persists (see
“Contacting Waters Technical
Service” on page 4-2 ). Most of these errors are encountered on startup.
The table below provides startup, calibration, and operating error messages,
descriptions, and recommended actions you can take to correct the problem.
Refer to “Wavelength verification and test” on page 1-9 , “Verifying the
detector” on page 3-27 , and “Wavelength calibration” on page 3-30 for
verification and calibration information and procedures.
