Teledyne API T801 NDIR CO2 Analyzer Operation Manual Getting Started

INTERFERENTS
Some gases, if present in the sample stream in high concentrations, could
potentially interfere with the analyzer. For example, if the Sample Gas to be
measured contains high levels of nitrogen dioxide (NO
2
) and/or nitrous oxide
(NO), the gases used for both the zero point calibration and the span calibration
should contain the same components in the same proportion in order to cancel
any interference effects.
3.3.2.2. BASIC PNEUMATIC CONNECTIONS
IMPORTANT
IMPACT ON READINGS OR DATA
Sample and calibration gases should only come into contact with
Stainless Steel, PTFE (Teflon) tubing, glass or electroless nickel.
ATTENTION
COULD DAMAGE INSTRUMENT AND VOID WARRANTY
Remove dust plugs from rear panel exhaust and supply line fittings
before powering on/operating instrument. These plugs should be
kept for reuse in the event of future storage or shipping to prevent
debris from entering the pneumatics.
CAUTION - GENERAL SAFETY HAZARD
The exhaust from the analyzer’s internal or customer supplied external
pump MUST be vented outside the immediate area or shelter surrounding
the instrument.
See Figure 3-4 for the location and descriptions of the various pneumatic
inlets/outlets referred to in this section
