Absorbance And Message Icons - Waters 2489 Operator's Manual

displayed before the detector was last powered-off. The absorbance screen
continues to change as the run continues.
The detector monitors absorbance of one or two wavelengths in real time,
while allowing you to modify all the parameters discussed in the table below.
You can use the A/B key to toggle between absorbance screens for channels A
and B.

Absorbance and message icons

The absorbance screens and message screens in the detector program display

Function
Selects the chart sensitivity in
absorbance units full-scale (AUFS) for
the selected channel (Ethernet signal is
not affected).
Selects the wavelength monitored on the
selected channel. When in single
wavelength mode there is no independent
control of wavelength on channel B.
Displays which channel is selected when
you press the A/B key. The selected
channel overlaps the other channel.
Displays the ON A or ON B icon for the
channel on which a timed or threshold
event is programmed.
When you press the TRACE key, displays
only the channel being viewed.
