Primary and secondary functions
You can access the following functions directly from the absorbance screen or
by pressing the Next key on that screen.

Function Description
Wavelength Defines the operating wavelength for the channel.
AUFS (absorbance
units full-scale)
Defines the relationship between the absorbance and
the output voltage. The output voltage reaches full
scale (2 V) when the current absorbance attains the
AUFS value.
Caution: Changing the sensitivity (AUFS) setting
affects the 2-V output.
Analog out
(single λ)
You can chart out the analog connections for the
following parameters:
• Absorbance - Charts the current absorbance of the
selected channel analog output 2-V connector
(scaled to the AUFS setting for that channel) and
adjusted based on the voltage and absorbance
offsets for that channel. For the 2-V output with 0
used for both the voltage and absorbance offsets:
Volts out = Absorbance × 2 V/AUFS
