Signal
You can select the signal source used for all data outputs. This includes
display on the operation screen as well as analog and digital data
outputs. You can select the options absorption, signal and reference
channel. The values sig and ref give the measured light intensity on the
signal and the reference channel respectively. The sig and ref values
range between 0 and 1, their absolute values are dependent on the
wavelength, the solvent, the flow cell used and the age of the lamp.
SCAN OUT
You can select the output speed of scan data via integrator output.
Available values are 1, 2, 5, 10, 20 and 50 steps per second.
ANALOG OUT FULL SCALE
You can scale the two integrator outputs according to your needs.

In the first field you can choose the signal range covered by the output
signal. Values that can be chosen by arrow keys from 10
16 steps. In the right hand field you can choose the maximum output
voltage from 0.1, 1 and 10 V.
ANALOG OUT OFFSETS
You can set an offset to the two integrator outputs. The output voltage
of the outputs is set to zero during the self test of the instrument. In this
window, you can set a numerical value for an offset in mV units that will
be added to the corresponding signals on the analog outputs. This
function can be useful when using a chart recorder to separate the
charts for the two channels.
ANALOG IN
You can calibrate the analog input for external wavelength control.
Activating Set-Zero by pressing ∆ or ∇ on this field defines the actual
input voltage as zero, wavelength 000 nm. Then a signal is applied, e.g.
5V. The actual „λ" field shows the interpreted wavelength, that should
