104 GENESYS 10S Vis User Guide
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.
Note You can display the tolerances for this test in either absorbance or %Transmittance.
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.
To display the Photometric Accuracy screen
1. Highlight Photometric Accuracy.
2. Press Enter.
To switch between absorbance and %Transmittance, press Change to %T (or Change to
ABS) until the appropriate mode appears.
You will need to set three values whenever you add a standard: the wavelength, the absorbance
(or %Transmittance) and the tolerance value.
