Colibrick A/D Converter
4 Using the Colibrick
Channel 1 (to 4)
For each channel of the
Colibrick A/D Converter
the name of the signal
can be edited in the
Name
field and the
Set Units...
button can be used to
change other signal parameters. Effects of these changes can be seen in
other fields of the respective
Channel 1 (2) section
.
Name
This field will be used to describe the signal in the
window.
Inversion of Signal
Inverts the polarity of the signal from the detector. This function can
also be used for easy correction of inversely connected wires.
Bipolar
Both positive and negative voltages will be measured. Unchecking the
Bipolar
option will improve the resolution of the signal by 1 bit. On the
other hand, it will also restrict the measuring of negative signals (i.e.
below zero).
Set Units...
Invokes the
Detector Units
dialog that can be used for converting the
voltage measured by
Colibrick
to the units of the detector. Such units
will then be shown throughout
Clarity
instead of default mV. Setting is
specific for each
Colibrick
channel (signal).
Fig 11: Detector Units
Quantity
– Field for entering a name for the y-axis in the graph of the
measured signal.
Units
– Field for entering the unit symbol, along with the prefix.
Coefficient
– Allows you to enter the coefficient between the selected
units and mV (default).
Autoprefix
– Allows you to enter the unit prefix. In the graphs units will
be scaled automatically, while in the tables units with the prefix
entered will be used.
Synchronize Start with Digital Input
Maps the

channel to selected
External Start
Digital Input
. It enables a faster and more accurate synchronization of
channels with the start signal. Especially for short analyses the necessary
time delays at the start of the acquisition are significant. When measuring
multi- detector chromatograms it will minimize the time shift between
detector signals and thus improve the detection of peaks.
