1.6.4 RS-232

The RS-232 connection is a male, 9-pin D-sub connector at the location shown in Figure 1.2.

1.6.5 Pneumatic system

The Model 300 is equipped with a vacuum pump capable of pulling 800 cc/min across a critical flow orifice. This allows a smooth, stable flow of sample through the Analyzer.

Sample enters the Analyzer through a 5 micron TFE particulate filter element (37 mm diameter) mounted immediately behind the front panel. The sample then enters directly into the sample cell. Please see Figure 1.3 for a flow diagram and Figure 1.4 for pneumatic connections.
