Detector Setup Parameters
In setup mode, you can view and if necessary
modify the setup parameters currently specified for
the detector.
First Display For Setup Mode
Following is a description of the parameters on the
first display for setup mode. When you're finished
checking or changing parameters, press the Next
soft key to reveal the next display for setup mode.
Description
For each output channel, set this parameter to
show the full-scale range. The default for each
channel is 10 mV, and the valid range is 1 to 1000
mV.
For each output channel, use this parameter to
move the baseline away from the 0 position of the
strip chart. You should specify a channel offset
that is up to half the full-scale range set for the
channel. The default for each channel is 0 mV, and
the valid range for channel offset is 0 to 1000 mV.
This parameter does not affect the output; it just
enables you to see a negative change in output.
Channel offset is useful for gradient analyses where
a change in the gradient causes the absorbance to
decrease and become a negative value.
Note: If you're using Gilson control software and
collecting data via the GSIOC, the software uses
the mV full scale and % offset parameters set in its
dialog box(es). The software does not use the
channel scale and offset parameters set in the
detector.
