Self-test
The DAD self-test (see Figure 64 on page 163) runs a series of individual tests,
and evaluates the results automatically. The following tests are run:
• Filter Test
• Slit Test
• Dark Current Test
• Intensity Test
• Wavelength Calibration Test
• Holmium Test
• Spectral Flatness Test
• ASTM Noise Test (optional)
The self-test can be run once or repetitively. When set up to run repetitively,
the tests run in series continually until stopped by the user. Running the test
repetitively is useful when troubleshooting problems which occur
intermittently.
The ASTM noise test determines the detector baseline noise (254nm) while
pumping water at 1ml/min. The test requires approximately 20 minutes to
run, and can be included or excluded from the self-test sequence as required.
Setup of the self test is done in the Self Test dialog box. Select either Single
Test or Repetitive Tests. Check the ASTM Noise Test checkbox to include the
noise test in the self test.
