3.2.4 Primary and secondary functions
You can access the following functions directly from the absorbance screen or by
pressing the Next key on that screen.
Table 3–1: Detector functions
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
)
This function charts the current absorbance of a
selected channel’s analog output, 2-V connector
(scaled to the AUFS setting for that channel) and
adjusts the absorbance value according to the voltage
and absorbance offsets for that channel.
Example:
For the 2-V output with 0 used for both
the voltage and absorbance offsets;
Volts out = Absorbance × 2 V/AUFS
