Wavelength Accuracy - Internal
This test locates the peaks of the internal xenon lamp and displays the expected and measured
wavelengths for the peaks.
A xenon lamp has strong, fundamental lines at 229 nm, 529 nm and 883 nm. These lines are
an essential property of xenon and serve as a fundamental standard.
When running the internal standard test, remember that:
• The wavelengths and tolerance values are preset and cannot be changed.
• The cell holder should be empty.
Y To run the Wavelength Accuracy - Internal test
1. Highlight Wavelength Accuracy - Internal and press Enter .
2. Press Start Test .
The results indicate pass or fail for each wavelength.
If the test fails, follow these guidelines:
• Repeat the test twice to verify that the test is failing consistently.
• Contact technical support for more troubleshooting advice.
Wavelength Accuracy - Standard
This test measures the absorbance of a wavelength accuracy standard and compares the
location of the peaks with precisely known values at up to five wavelengths. By default,
wavelength accuracy tests are performed in absorbance mode; however, this test may also be
performed in %T mode. Typical wavelengths and tolerances are included in the firmware, but
these values can be changed to match the calibration certificate included with your standards.
