Test Functions

Holmium Oxide Test
The built-in holmium oxide filter is used for verification of wavelength
accuracy at three additional wavelengths. The test evaluates the results
automatically, and provides a spectrum of the holmium oxide filter.
Intensity Test
The intensity test checks the lamp intensities (UV and visible lamps) over the
complete spectral range. The test evaluates the results automatically, and
provides an intensity spectrum.
Cell Test
The cell test compares the lamp intensities with and without flow cell
installed. The intensity ratio is an indicator of the amount of light absorbed by
the flow cell (e.g. contaminated or dirty cell windows).
Dark-Current Test
The dark-current test measures the leakage current from each optical diode.
The test evaluates the results automatically, and provides a graphical output
of the results.
Filter Test
The filter test checks the filter motor for correct movement, and checks the
absorbance of the holmium oxide filter in order to determine whether the
filter is dirty or contaminated.
