2.17.2 Analog Outputs
When the I/O option is installed, two analog outputs (one for each detector)
are installed on the DC rear panel (see
Figure 2-31 ). The analog outputs
supply a voltage signal proportional to the current measured by the detector
cell. The outputs can be connected to an analog-to-digital (A/D) converter
such as an integrator or other recording device. Refer to
Section 2.17.1 and
the documentation for the device for connection instructions.
Several settings are available that allow you to configure the analog output
signal for your detector and connected device.
Table 2-4 describes the
settings. You select the preferred settings on the detector panel on the
Chromeleon 7 ePanel Set (see
Figure 2-34 ) or Chromeleon 6.8 panel tabset.
Analog Output
Setting Values Description
Full-scale voltage 0.01, 0.10, or 1.00 V Sets the voltage output of a full-
scale detector response. The
voltage to use depends on the
recording device to which the
analog output is connected. For
example, if the analog output is
connected to a device that
accepts input voltages up to 1 V,
select a full-scale voltage output
of 1 V.

Sets the full-scale detector
response value. The range to use
depends on the detector readings
expected for the application. For
example, selecting a range of

you to viewing conductivity
