3.4.4.3 Configuring the Analog Outputs
Make the required settings for the analog outputs in Chromeleon.
1. On the Detector page in the Properties dialog of the detector, verify that the DAC
Board check box is selected (→ page 42). When the check box is cleared, the analog
outputs will not be available in Chromeleon.
2. Open the Commands dialog box for the detector.
3. Make the required settings.

Description
Sets the signal that is available at the analog output.
Adjusts the zero position of the analog output when it is plotted. The value
entered is a percentage of the full-scale analog output. The offset allows the
evaluation device to plot the signal if it becomes negative.
Even with a very small, positive analog output signal an offset of 5 %, for
example, should be set, because the minimum output voltage of the analog
output cannot be exactly 0 V.
Sets the value range, and thus the resolution of the analog output signal.
The range to use depends on the values expected for the application and the
evaluation device to which the output is connected.
Sets the maximum voltage value of the analog output signal (1 or 10). The
range to be used depends on the input voltage of the evaluation device to
which the output is connected.
