Trace Oxygen AnalyzyzerInstallation 3.0Installation3.1 LocationWith proper shielding of the leads, the analyzer and the readout devicecan be separated by as much as 1,000 feet. However, they should be placedas close together as possible. For the most convenient operation, the readoutrecorder or meter should be within view of the controls, particularlywhen the unit is being calibrated. Other location considerations:1) The analyzer should be sheltered from the elements.2) Ambient temperature must be within 30 to 120 °F.3) The unit should not be subject to excessive shock or vibration.4) It should be as close as possible to the sample point.5) There must be access to the back and side of the unit forconnection or maintenance of sample lines and power.NOTE: Since the level of the electrolyte in the measuring cell is critical andthe water level control system for the humidifier is gravity sensitive,THE ANALYZER MUST BE MOUNTED SO THAT THE BOTTOM OFTHE CASE IS LEVEL.Figure 3 depicts a typical system layout.3.2 Electrical ConnectionsA diagram of the necessary electrical connections is shown in Figure 4.Note: See the Interconnection Diagram (drawing A-21916) included in theback of this manual, as well as any Addenda that may be includedwith this manual for information specific to your instrument.The connections include a terminal for grounding the analyzer case andchassis in accordance with accepted industrial practices. The maximumpower requirement is less than 1½ amperes at 115 VAC.TELEDYNE ELECTRONIC TECHNOLOGIEAnalytical Instruments3-1
