ANALOG OUTPUT
Connectors
The four analog outputs are standard female BNC connectors. The output range is
0 to 1 volt. The full-scale absorbance range can be set to 0.0005, 0.001, 0.01, 0.1,
0.5, 1.0, 2.0, or 3.0 AU full-scale in Chromeleon. For details about programming
the analog outputs, see
Section 3.3.2 .
The analog outputs will continue to output data after the PC is turned off or is
disconnected from the Dionex PDA. When the detector power is turned on again,
the analog output settings will be either the factory defaults (see
Section 3.3.3 ) or
the settings selected the last time the detector was controlled by the computer.
Drain Tube Connector
Waste exits the detector via a drain tube (P/N 055075) connected at the rear panel.
When correctly installed, the drain tube is routed downward, below the leak tray.
For installation instructions, see
Section B.4 .
Figure 2-8. Dionex PDA Rear Panel
Check periodically to verify that the drain tube is not clogged or
bowed upward, and that the tubing remains routed below the leak tray.
If the drain tube is above the drain port, the drip tray may back up and
overflow inside the detector.
