2.18.2 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 2-15
). 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 2.18.1
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 2-2
describes
the settings. You select the desired settings on the detector Control panel
(see Figure 2-46
).
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.
Range Conductivity:
0.01 to 15,000 μS
DC Amperometry:
50 pA to 300 μA
Integrated
Amperometry:
50 pC to 200 μC
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 20 microSiemens (μS) will
limit you to viewing conductivity
readings of 20 μS or less.
