A recording and/or indicating device will be required to transduce the electricaloutputsignalintoreadableinformation.
2.INSTALLATION
2.1Location.
The analyzer should be panel mounted in an upright position in an area that is notexposedtothefollowingconditions:
1.Direct sunlight.
2.Drafts of air.
3.Shock and vibration.
4.Temperatures other than that one would expect to see in airconditioned, temperature controlled office of lab enviroment.
The 212R should not be mounted outdoors or subject temperature fluc- tuations beyond 2 or 3 degrees.
The analyzer should be placed as close as possible, subject to the afore- mentionedconditions,tothesamplepoint.

2.2Electrical Requirements and Connections.
Provisions have been made to accommodate the three external circuit connections required by the analyzer. Access holes on one side of the analyzer case (see Outline Diagram) are provided for the installation of the conduit and electrical wiring. All three customer connected circuits are to be terminated on thebarrierterminalstripidentified“TS1”.
