Attenuation in RIU-FS (comparable to the Sensitivity parameter in 410 mode)
–
Where the analog output channel reaches its full value of
±
2 volts, you can
specify a scaling factor in RIU mode for the analog output channel that
corresponds to the refractive index value. RIU-FS varies from 1 to 500 µRIUs.
Note:
Changing the attenuation (RIU-FS) setting affects only the 2-V analog
output.
•
Filter Type – In RIU mode, the filter can be set to the digital Hamming or RC
types.
•
Filter time constant, in seconds – You can program a filter time in seconds.
Selecting a value of 0.0 disables all filtering. The default value is 1.0 seconds.
From the RIU mode home screen, pressing Next brings you to a fourth page of
secondary, or less frequently used, parameters:
•
Voltage offset, in mV – You can program a voltage offset in millivolts. Only the
analog output is affected.
•
Micro RIU offset in µRIUs – You can program a µRIU offset. Only the analog
output is affected.
•
Enable keypad – You can program whether these keypad function keys can be
accessed:
–
Purge on keypad/panel active
–
Recycle on keypad/panel active
–
Auto-Zero on inject on keypad/panel active
–
Auto-Zero delay, from 0 to 30 seconds
–
Chart mark on keypad/panel active
–
Auto-Zero on keypad/panel active

410 emulation mode
In 410 mode, the detector monitors a single channel, in millivolts, and does not
support standalone method programmability. Control is provided via the data system
software or Alliance system. You can configure several additional parameters when
using the detector in 410 mode:
•
Sensitivity – Used in the scaling of the refractive index data in millivolts and
affecting the front panel display, analog outputs, and remote interface data.
Sensitivity is used only to generate Waters 2410/410 RI Detector-compatible
data for older data systems and controllers.
•
Filter type – In 410 mode, the filter is always set to RC.
•
Filter time constant, in seconds – You can program a filter time in seconds.
Selecting a value of 0.0 disables all filtering. The default value is 1.0 seconds.
From the 410 mode home screen, pressing Next brings you to a fourth page of
secondary, or less frequently used, parameters:
•
Voltage offset, in millivolts – You can program a voltage offset in millivolts. Only
the analog output is affected.
•
Enable keypad – You can program whether these keypad function keys can be
accessed:
