Quick Noise Test

Quick Noise Test

The quick noise test measures the noise of the detector, with Max-Light Cartridge
Cell or with Max-Light Cartridge Test Cell installed, in one minute intervals over a
total of 5 minutes.
The noise of the detector is calculated by using the maximum amplitude for all
random variations of the detector signal of frequencies greater than one cycle
per hour. The noise is determined for 5 one minute intervals and is based on the
accumulated peak-to-peak noise for the intervals. At least seven data points per
cycles are used in the calculation. The cycles in the noise determination are not
overlapping.
If the test is performed with the Max-Light Cartridge Test Cell, the test results are
not influenced by solvent or pump effects.
When In case of noise and drift problem.
