Parameters Description
Autozero Performs an automatic null balancing. The current
detector signal is interpreted as 0 at the current range in
use.
Data collection rate Defines the number of data points per second (Hz) that
the Chromeleon software collects from the detector and
stores as raw data.
For further information, see
Filter Constant
Filter constant Applies a filter constant to the output current to
electronically reduce the baseline noise during the
analysis.

Filter Constant
Leak detection Leak detection is enabled as a standard when the
detector is shipped (Leak Sensor Mode = Enabled). This is
the preferred setting.
Peak width Defines the width of a chromatographic peak at the half
of the peak height. Specify a peak width for the narrowest
expected peak in your chromatogram.
As a standard, when you set the Peak Width, Chromeleon
automatically calculates values for the Data Collection
Rate and the Filter Constant.
Power function Sets by what factor a linearization is applied to the data
output. As a standard, the Power Function is set to 1.00.
