IMPORTANT: The foam lining the interior of the analyzer is an integral part of the environmental temperature control system. Removal or destruction of this lining will result in erratic instrument perfor- mance.
2.2.1 Primary Power.
A source of single phase, 105 to 125 volt, 60 cycle power will be required to operate the analyzer. The maximum power consumption of the analyzer is 500 watts.
NOTE: The analyzer is also available for 50 cycle operation with special modifications and accessories.
RefertotheInterconnectionDiagraminthedrawingsectionofthemanual and connect the power and ground wiring as shown. Be sure to polarize the power service connections as indicated. When connecting the wires, do not leave an excessive amount of slack within the analyzer. Two vacuum tubes are located just below the wiring area and the wiring should be installed to be well clearofthem.
2.2.2 Signal Output.
Connect a two conductor shielded cable between the analyzer and record- ing equipment. Be sure to observe the proper polarity at both instruments. Connect the shield of the cable on the indicated terminal at the analyzer only, and cut back and insulate the shield at the recorder.
NOTE: Connecting the shield at both ends of a cable when dealing with low level circuits can create a ground loop between two instruments. Improperly installed shielding can produce more noise in a low level circuit than no shielding at all.
2.2.3 Regulating Transformer.
