Page 143: Chapter 4 Calibration
Zero Air Generator Since the 48iQTL instrument is equipped with an internal CO scrubber, a separate source of zero air is not required for routine single point calibrations. However, dilution air to generate span gas from a higher concentration cylinder requires zero air that is free of contaminants which will cause a detectable response on the CO analyzer.
Page 144: External Flow Meter(S) And Controller(S)
So cylinder zero air should be scrubbed of the residual CO prior to its use in the 48iQTL as a dilution gas or a zero standard. Room air which has been scrubbed of CO can also be used as the zero air source.

Page 231: Chapter 8 System Description
Chapter 8 System Description The 48iQTL deploys a set of modular subsystems that comprise the total instrument function. The core measurements for concentration are contained in Distributed Measurement and Control (DMC) modules. This chapter describes the function and location of the system components in the module framework, including firmware, electronics, and I/O function.

System Description Optical Bench DMC Figure 8–1. 48iQTL Flow Schematic with Filter Wheel Purge Calibration Note The stability of the purge gas is very important. Since this gas is in the same optical path as the sample, changes in the composition of the purge gas can change the calibration of the instrument.

The rear panel fan, which is part of the common electronics in other iQ analyzers is repurposed in the 48iQTL to provide tight control over air flow into the instrument. The rear panel fan is plugged into the optical bench DMC board which controls the fan speed to help maintain a stable instrument temperature.

All electronics operate from a universal VDC supply, which is capable of auto-sensing the input voltage and working over all specified operating ranges. The 48iQTL contains a 24 VDC channel for most electronics operation, including the pump and fan, and a 48 VDC channel dedicated specifically for optical bench heating.
