Connecting the detector to a 745/745B/746 data module
You can connect the detector to a Waters 745/745B/746 data module using the
analog output connector on the rear panel of the detector. The analog
connector provides 2-V output that is scaled to the AUFS sensitivity setting
and the voltage offset setting.
To send the analog output signal from the detector to the data module, use the
cable provided in the 2489 Detector Startup Kit to make the connections
summarized in the table below and illustrated in the figure below.
To minimize the chance of creating a ground loop that can adversely affect
measurement, connect the shield of the cable to the chassis ground at one end
only.
Caution:
To prevent oversaturation of the signal from the detector to
the integrator, do not exceed the input voltage rating of the
integrator.
