Noise Measurement
This test measures the amount of noise. The Vis instrument measures only at 340 nm. All test
parameters are determined by instrument specifications and cannot be changed by the user.
When running the noise test, remember:
•
Perform the 0A measurement with the vial holder empty. Optionally you can perform the 2A
measurement with a 2A filter.
To run the Noise Measurement test:
1.
Press the test key to access the Test Types menu.

Press the ▲or ▼ key to highlight Performance Verification and press the enter key.
3.
Press the ▲or ▼ key to highlight Noise Measurement and press the enter key.

2A if you do not have a filter installed in position #1.
5.
Press the Start Test function key.
6.
The results will 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.
