Average (Chromeleon 6.8 only)

The Average parameter operates in conjunction with the Step parameter
(see Section
When Average is On, Chromeleon 6.8 averages the data points between
Step intervals and reports that value. Noise is reduced. This setting is
recommended for most applications.
When Average is Off, Chromeleon 6.8 reports the data points at the step
interval. The data points between steps are skipped and noise is not
reduced.

Sample Wavelength Selection

The Dionex VWD can measure absorbance in the wavelength range from
190 to 900 nm. Set the sample wavelength to the wavelength with the
absorbance maxima for the analytes of interest. See
of the UV absorbance wavelengths of common chromophores.

Shutdown

3.6.1

Short-term Shutdown

If the detector will be shut down for one week or less, make sure that any
caustic eluent, with pH higher than 8, is removed from the flow cell by
flushing with water. No other special shutdown procedure is required.
The Smart Shutdown feature in Chromeleon 7 or Chromeleon 6.8 can
assist you in creating and running a shutdown or standby procedure. For
shutdown, the detector lamps must be turned off (because the pump flow
is off). For standby, you can choose whether to turn off the lamps or leave
them on (because the pump flow remains on during standby). For details
about Smart Shutdown, refer to the Chromeleon Help.
