 To run the Noise Measurement test
1. Highlight Noise Measurement.
2. Press Enter.
3. With the Blank position empty, insert the 2A filter in position #1.
Ignore the test results at 2A if you do not have a filter installed in position #1.
4. Press Start Test.
The results of the test 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.
• Make sure the instrument is warmed up for at least 30 minutes, with the standby mode
feature turned off.
• For more troubleshooting advice contact our sales or service representative in your area or
use the information at the beginning of this document to contact us.
This test measures the stray light at selected wavelengths and compares the measurements
with expected values. The wavelengths and expected values are preset and cannot be changed.
Running the stray light test takes about 30 seconds.
When running the stray light test, remember:
• You need Stray Light standards designed to measure stray light at 220 nm (UV-Vis only),
340 nm and 400 nm (i.e., must have 0.1 %T at the wavelength of interest).
