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.
Photometric Accuracy
This test measures the absorbance (or %T) of a set of standards and compares the results with
specified tolerances. The wavelength absorbencies and tolerances are preset, but you should
change them to the values on the calibration certificate included with your standards.
When running the Photometric Accuracy test, remember:
• You need Photometric Accuracy standards calibrated to known absorbance values at
specified wavelengths.
• Measure the standards in the order they are listed on the test screen.
• You can use one to five standards.
